And that is where we're going to leave it. Fourteen teams have been reduced to three, and after six failed attempts, co-hosts New Zealand have finally reached their first World Cup final. You can already read Stephan Shemilt's match report on the BBC Sport website.,
It ends there for South Africa - but not for the tournament. It's over to Sydney on Thursday where Australia and India meet for the right to play NZ in the final. Play gets under way at 03:30 GMT - so set your alarm clock and make sure you join us on the live text from 03:00.
That's it from us. New Zealand have their dream final, and South Africa, I think, can hold their heads high after a superb game. Goodbye for now.

New Zealand batsman Ross Taylor: What a game. What's the first thing you do when u win a semi? Everyone cleans their boots for Oz customs.
Captain Brendon McCullum, as he does so often, gave New Zealand impetus with a characteristically pugnacious 59 from 26 balls. Their hopes eventually rested with a century stand from Grant Elliott and Corey Anderson.
While Anderson holed out for 58, Elliott - who was born in Johannesburg and learned his cricket in South Africa before moving to New Zealand - saw the Black Caps home with an unbeaten 84 from 73 balls.
In a thrilling finish, Elliott launched Dale Steyn, the world's premier fast bowler, for six into the stand from the penultimate ball of the match to book their place in Sunday's final, leaving a couple of South Africa players in tears.
Former All Blacks hooker and captain Sean Fitzpatrick on BBC Radio 5 Live: "It was fantastic. The whole of New Zealand has got behind the cricket team and I think as AB de Villiers said post match, it was the most electric atmosphere.
"The whole World Cup has been fantastic. Brendon McCullum has turned this team around from four years ago. They have come out and played a brand of cricket that is being enjoyed all over the world.
"They have stayed under then radar a bit, had a good build-up but have come in and delivered. Players like McCullum, Daniel Vettori and Ross Taylor are just phenomenal. They are amazing to watch."
It all began just under 10 hours ago when South Africa walked out to bat after winning the toss. Trent Boult struck twice early on, but Faf du Plessis (82), Rilee Rossouw (39) and AB de Villiers (65 not out) took the Proteas to 216-3 from 38 overs when the rain came - which reduced the game to 43 overs per side.
David Miller then took the initiative with 49 from 18 balls to help SA post 281-5 - with New Zealand being set an adjusted target of 298 from 43 overs via the Duckworth-Lewis method.
On Twitter: "South Africa DID NOT CHOKE. They got beaten by a better team today. AB led the team wonderfully well. But, well done NZ. See you in Sydney."

Earlier today, prompted by the TMS panel discussion during the rain break, we were asking you what rule changes you would like to see made to one-day international cricket.
On reflection, the rules of a game which produces a finish like we've just had... can't be THAT badly wrong, surely?

Mark Pettman, trying to concentrate in the City: What a game. But three missed run-outs and a dropped catch will haunt South Africa for years.
Wayne, UAE: South Africa choosing to bat first knowing there were high probability risks of poor weather impacting the first innings resulting in reduced overs was a stupid decision.

More from NZ all-rounder Corey Anderson on Sky Sports: "Everyone in the team knows they have got a job to do. Although we've got through, we still have not achieved what we want to and that's win the World Cup.
"We've been trying to play with smiles on our faces and please the people of New Zealand. They have fallen in love with the team and hopefully we can go out on Sunday and put in a good performance.
"It's going to be the first time for a lot of us to play at the MCG, it's going to be the biggest event that we've ever played in. The crowd will not be like it's been here if Australia go through. Their crowd will be on us, but that's something we're looking forward to."

Player reaction
New Zealand all-rounder Corey Anderson on Sky Sports: "It's a dream come true. There have been a lot of teams trying very hard for New Zealand to try to get to the final and we're lucky enough to be the team to do it.
"Brendon (McCullum) is massive for us. He teed off and put us ahead of that run rate, and they struggled to come back after that. That's what he has been doing all tournament and he's very good at it. Even though he got 50, it would be nice for him if he gets a big score on Sunday. We could have lost a few wickets and fallen in a heap but to get 298 off 43 overs is a massive chase."

Elsewhere in the world of cricket, BBC Radio 5 live sports extra have switched over to Abu Dhabi where it's day three of the Champion County match between MCC and Yorkshire.
More from New Zealand captain Brendon McCullum: "All credit to South Africa, the way they have played has been a great advert for cricket and their country. They gave us one hell of a run.
"It's the greatest time of our lives as players. It's an incredible ride, the crowd has supported this team and the brand of cricket we have played. Hopefully they're dreaming like we are. It would be nice to win it. Both teams in the other semi-final are quality teams and we know if we play the way we can we have a chance."
"Even De Villiers took the mantle to bowl, and you could arguably say he was one of South Africa's best bowlers. To go for 21 off three overs, at a time when New Zealand needed boundaries - he gave it absolutely everything in this game."
Captain's view
More from New Zealand captain Brendon McCullum: "It was a great advert for cricket. Everyone that was here will remember it for the rest of their lives. We have given ourselves a chance of World Cup glory and I'm proud of our efforts.
"We knew we just had to hang in there and give ourselves a chance. At the end what a great innings from Grant Elliott. He came out of the wilderness not long ago and now just played a match-winning innings in a World Cup semi-final."
"To be fair to South Africa, someone up there doesn't want them in a final, but their time will come - they're oozing with talent. Before that rain break, they were going to post 360-370 and that would have been too much for New Zealand. You can't talk about choking."
More from New Zealand batsman Grant Elliott who scored 84 not out and hit the winning six: "Hopefully, all our supporters got what they wanted. We've had two close, amazing games here now.
"We will probably have a few drinks in the changing rooms. I don't like to get too high or low - I prefer to reflect later - but it is a great moment to share with family and the team. The win is for the supporters.
"I think we left it a little too late. I can say that now even though we won it. South Africa have a world-class unit and they bowled well. We got a bit of luck but it was our day.
"The feeling in the team is that it is destined. That is how I felt. It feels like it was meant to be. The best team on the day will win the final. We have nothing to lose. Someone has to step up."
"I honestly thought South Africa had done enough with three or four overs to go, but Grant Elliott stayed so calm out there. You have to feel sorry for Dale Steyn and Morne Morkel, great professionals who gave it everything out there, but hats off to New Zealand."

South Africa have entertained - but fallen short. Thoughts now turn to those who might not be around at the next tournament in four years' time. Dale Steyn, for instance, will turn 36 in the summer of 2019, will he manage to get his battered body through another four years of international cricket between now and then? Hashim Amla will be 36. De Villiers 35, Morne Morkel 34. And Imran Tahir, who will be 36 on Friday, will be 40 by the time the next World Cup comes around.

To see Grant come in and be as calm as he was... we've given ourselves a chance of the big prize. Credit to South Africa, they gave as good as they got. I feel for them at the moment. But out boys were outstanding. And it was a great semi-final.

Man of the match
New Zealand's Grant Elliott: "It is great. I don't think this win is for myself, or the team, it is for everyone here. The support has been amazing.
"We just wanted to take it as deep as we could. Corey (Anderson) batted well and we timed the innings to perfection. When you have 40,000 fans screaming at you every ball, it has been an absolute pleasure playing at Eden Park and playing in front of the home crowd.
"We have had a good run, this is the first final we have been in and we will approach it as any other match."
"This is the first time New Zealand have won 10 consecutive ODIs."
Man of the match
New Zealand batsman Grant Elliott, who made an unbeaten 84 from 73 balls and hit the winning runs, is handed the man-of-the-match award by the unmistakeable figure of Windies legend Clive Lloyd. We'll hear from him shortly.
Post update
New Zealand batsman Corey Anderson on TMS: "It feels unbelievable. The best feeling I've ever had. We haven't achieved what we want yet. We want to win the whole thing.
"That was a big score to chase in 43 overs, but to do it with one ball to spare... Everyone chipped in when they needed top. Brendon put us on the front foot and that made it easier for the guys coming in.
"To stay calm like that and hit a six off the best bowler of the world. Its unbelievable."

Coney's right - cricket can be a cruel game. For on an occasion like this, there has to be a winner and a loser.

"Marvellous scenes. You should see 40,000 people starting the party. I'm so sorry for South Africa.
"Sport becomes cruel in these circumstances. Don't talk to me about choking. They have given everything they could and they tried hard. The rain cruelly prevented South Africa going any further in their innings.
"What a fantastic game of cricket. It has captivated people, not just in the stadium, but around the world. It is a very good example of cricket."
Final scorecard
New Zealand 299-6 (42.5 overs) - target 298 from 43 overs (D/L adjusted)
The fireworks are set off around Eden Park, amid scenes of jubilation rarely seen there except at a packed rugby international. An astonishing game of cricket, players console each other, and Morne Morkel has even started shedding a few tears.
"He's put Dale Steyn, the world's premier fast bowler, into the stand, and South Africa have been denied again."
Champagne moment
New Zealand win by four wickets!
Unbelievable! Steyn delivers and Elliott launches the ball high into the stands. Eden Park erupts. Elliott, the South African-born player has sent New Zealand through to their first World Cup final at the expense of his home country. What a game of cricket!

NZ 293-6
Six to win outright. Five to go through with a tie. Swing, miss, they run a bye, keeper's throw misses the stumps, then Steyn's throw misses the other stumps. Five to win the match, but four to go through.

Maddy Raman: Duminy what are you doing? Never your catch. Sheer panic descending into both teams.
"It ran quickly to wide third man. You just run whatever now."
NZ 292-6
Vettori has been a hero for NZ so often through the years. Can he be again here? Steyn bowls a wide full toss and Vettori stabs at it and sends the ball spinning down to the boundary where it beats a diving fielder. And just like that, the game is the co-hosts to win again.
Post update
Physio on. If Steyn can't finish the over... Morkel and Tahir have bowled their allocation. Three bowlers can bowl nine and two can bowl no more than eight. Philander has bowled eight. So if Steyn can't bowl, it would have to be Duminy or De Villiers.
But it looks like the old warhorse is up on his feet. 10 from four balls needed.
"It looks like cramp. Dale Steyn was off the field earlier as well. So far, it is advantage South Africa. Vettori is on strike and he can't afford to miss the ball. New Zealand need a four."
Ouch!
And now Steyn looks like he has cramp... it's all happening!
NZ 288-6
Elliott facing. Field shuffled - mid-off and mid-on up. A low full toss is punched to extra cover, they can only run one. 10 from four balls.
NZ 287-6
The last over. It is Steyn to deliver it. Six balls to decide this gripping semi-final. Vettori swings and misses from the first ball but they run and claim a bye. 11 needed off 5.

Dropped catch
NZ 286-6
The Eden Park crowd are on their feet. 14 needed from seven, Elliott launches this one over deep square leg, and two fielders collide, wiping each other out as one tries to take the catch! Sub fielder Farhaan Behardien was under the catch and about to take it but JP Duminy came flying into him!
Two runs taken - 12 needed from the last over. Effectively 11 for a tie. Dale Steyn to bowl!
"Just enough width from Morkel to swing freely with the arms. He has just got it up and over cover."
NZ 284-6
New Zealand desperately need a boundary. They get one as well as Elliott smashes through the covers off the back foot. That keeps things firmly in the balance.
NZ 280-6
Vettori takes guard to Morkel. He steps across and books down to fine leg where some superb fielding from Steyn restricts them to one. 18 needed from eight.
Elliott adds another single with an ugly pull shot that he doesn't connect with but steers the ball to leg. Tense does not even begin to cover this.
NZ 278-6
Elliott on strike. He lofts the ball over the on side, three fielders converge but none of them can get there in time and they run two. 20 needed from 10.
"It needed quick hands. The throw was almost a half-volley at the keeper's feet. It was a difficult take for De Kock."
Close!
NZ 273-6
Elliott steers Steyn for two, then takes another risky second into the gap near the square leg umpire, but the throw is a little wild and De Kock can't take it cleanly. 25 needed from 15 balls.
"It was a pick-up stroke from Ronchi from just offside off. There was only one man in the leg-side and he picked him out."

WICKET
Ronchi c Rossouw b Steyn 8 (NZ 269-6)
Dale Steyn to bowl - and strikes as Ronchi holes out at deep square leg! Send for Vettori...
And while - correctly - the target is 298, we remind you that if New Zealand make 297, the match is tied but NZ go through as they finished higher in the group stage.
"It is very easy to lose one and then two when panic rises and you forget to think. It can still change very quickly, even this late in the game."
NZ 269-5 (target 298 from 43 overs)
Elliott whacks a single to mid-wicket where Amla does the fielding - but the bearded opener can't get to the next ball as Ronchi flicks it towards cow corner for four. However, some good fielding by Rossouw at long-on restricts them to a single off the last ball and means the Kiwis' requirement is 29 from 18 balls.
Tension? Gotta love it.

Who to bowl? Four to go - Steyn has two, Philander, Morkel and Tahir have one apiece, while I doubt we'll see Duminy or De Villiers bowl again. It's leg-spinner Tahir who gets the nod. A Ronchi single is followed by two dot balls - 35 from 21.
NZ 262-5 (target 298 from 43 overs)
Two more singles mean it's 10 off the over. 36 from 24 balls needed, and a lot now rests on Elliott, who has 62 from 60 balls. Can Ronchi stay with him, or will it be the fairytale ending for old man Vettori to come in and hit the winning runs?

"You couldn't make it up. 'Wicket this ball,' says Graeme Swann, just before Corey Anderson skies the ball into the Auckland night. 'There was just too much pressure created by that over'."
"A fantastic over from Morkel. A bit of pace, a bit of bounce. Anderson missed a hook the ball before, but all he got was underneath it and the ball went very high."

Scorecard update - five overs to go
New Zealand 252-5 (38 overs) - target 298 from 43 overs (D/L adjusted)
Batsmen: Elliott 54 from 57 balls (one six), Ronchi 0 from 0 balls
Fall of wickets: 71-1 (McCullum 59), 81-2 (Williamson 6), 128-3 (Guptill 34), 149-4 (Taylor 30), 5-252 (Anderson 58)
And South Africa finally break the partnership - having dried up the runs with dot balls, Morkel fires in a bouncer which Anderson sends sailing into the stratosphere and there's snow on it by the time Faf du Plessis takes the catch. Or does he? There's a heart-rending couple of minutes while the umpires look at the replays - did the ball hit the wires of Spidercam? Apparently not - Anderson has to go.
The stadium DJ plays Michael Jackson's "Thriller". 46 from 30 balls? I'd call that a thriller. But it may be "close to midnight" by the time this game finishes...
"The highest successful run chase in any World Cup knockout game is the 289-4 Australia scored to beat New Zealand by six wickets in the quarter-final in Madras in 1996."
NZ 252-4
Tahir off, Morkel on as the skipper shuffles his front-line bowlers. With the game ebbing and flowing with nearly every delivery, the crowd is silenced after the Kiwis only manage a single off the first half of the over.
"It has been a very good partnership. New Zealand were in all kinds of trouble when Anderson came out to bat. They have worked it methodically to put themselves into this position. I'm enjoying this contest."
Appeal - not out
NZ 251-4
ABDV needs to find two more fifth-bowler overs from somewhere - so he comes back on himself. There's an appeal for leg before as Elliott tries to swing across the line - it looked quite high, and South Africa have no reviews left.
De Villiers fervently wipes the ball with a towel between deliveries as New Zealand keep plugging away with singles, but his last ball is too loose down the leg side and Anderson smashes it away for four through fine leg to bring up the century stand. 47 needed from 36 balls. Who's your money on?
"I'm very jittery in my seat. The best four teams are playing this week. And we have no idea who is going to win this match. It's still 50-50."
Elliott 50
NZ 243-4 (target 298 from 43 overs)
And now it's Elliott's turn to reach his half-century from a slightly slower 53 balls, lofting a four over extra cover. New Zealand are rather getting after Tahir here, and there is a feeling that the pendulum has swung Kiwi-wards. They need 55 from 42 balls.
On Twitter: Nobody is leaving Eden Park. It is an absolute thriller.
BBCCopyright: BBC
Anderson 50
NZ 237-4
It looks like South Africa want the ball changed - a tactic TMS legend Henry Blofeld refers to as "ballsmanship". After a brief visit from the fourth umpire and his attache-case full of additional spheres, the Proteas are told to get on with it. Imran Tahir back into the attack, but Anderson is in the zone now, smacking Tahir for a four square of the wicket before bringing up his fourth ODI fifty from 47 balls.
"Imran Tahir could break the game. He is such a fierce competitor."
Listen to Test Match Special commentary via the audio icon.
NZ 231-4
Anderson swipes Morkel wide of long-off, De Villiers gives chase and dives head first but can only succeed in pushing the ball onto the rope. A single means it's 12 from the over and Anderson (45 from 45 balls) is back on strike for the next over.
Six
NZ 225-4
Big over needed, KP? Righty-ho - Elliott launches the first ball of Morkel's over for six over square leg. 73 from 53.
"We are in for a nail-biter here. New Zealand need a big over. With two set batters you can get seven, eight, nine, 10 an over."
NZ 219-4 (Steyn 7-0-59-0)
Steyn to continue for his seventh over - he's allowed a maximum of nine today. Both sides are showing signs of nerves, whether running between the wickets hesitantly or nearly giving away overthrows, with every single potentially crucial. Elliott drives, it's in the air - but just wide of Du Plessis at short extra cover and they come back safely for two. Another single down the ground means both batsmen have 40 - Elliott from 49 balls, Anderson from 41. New Zealand need 79 from 54 balls. You'd have to be brave to call it definitively from here.
Corey Anderson is the first New Zealander to score 200 runs and take 10 wickets in a World Cup.
The others to have done this are India's Kapil Dev (1983) and Yuvraj Singh (2011), South Africa's Lance Klusener (1999), Zimbabwe's Neil Johnson (1999), Canada's John Davison (2003) and Sri Lanka's Sanath Jayasuriya (2003).

NZ 213-4 (target 298 from 43 overs)
A first-ball boundary takes some of the pressure off the batting side, and attaches it to the bowling unit. Anderson sees off the over before nicking the strike with a single.
One of these two sides will reach their first ever World Cup final today. But who will it be?
"We haven't had many, but this game could be an absolute stunner."
Powerplay
NZ 212-4
The batting powerplay is signalled - it's only four overs this one, because of the reduction in overs. Morne Morkel to bowl - and Anderson crashes the first ball through mid-off for four.

NZ 208-4 (Elliott 37*, Anderson 33*)
Steyn is bowling some serious heat here, but Elliott finds the gap with a back-cut which sails down towards third man, the lumbering Morne Morkel can't quite get to it and parries the ball onto the ropes for four.
"It was extremely tight. He has tried to knock the ball on to his stumps and hit it with his hand. It was amazing to see AB de Villiers, one of the world's best fielders, do that."
Not out
NZ 204-4
De Villiers tries to take the ball at the non-striker's end, with Elliott nowhere. But he drops the ball and knocks the bails off with his hand. Knowing that, as per the laws of cricket, he then has to pull up a stump, he overbalances and Anderson gets back.

NZ 203-4 (target 298 from 43 overs)
Captain AB de Villiers to bowl - can his gentle medium pace be a partnership-breaker, or just smuggle through an over or two to help Duminy complete his allocation? Elliott clips a single off his legs to take his side's score to 200. With no pace on the ball, New Zealand have to do the hard yards to work it around - four from the over pushes the required rate up to the verge of eight.
And would you believe, on Duckworth-Lewis... the scores right now are nearly exactly level. While we don't anticipate more rain, it's a good guide as to who's on top.

Kuni Poonasamy: I don't understand South Africa bowling so short. I know the boundary is short straight but let the batsman take you on.
"If they keep going at a run a ball for the next three overs, they will need 80 runs off their last 10 overs. South Africa need a wicket soon. New Zealand are in a good position to launch."
Scorecard update
New Zealand 199-4 (30 overs) - target 298 from 43 overs (D/L adjusted)
Batsmen: Elliott 32 from 37 balls, Anderson 30 from 27 balls (two sixes)
Fall of wickets: 71-1 (McCullum 59), 81-2 (Williamson 6), 128-3 (Guptill 34), 149-4 (Taylor 30)
And after that release of pressure, South Africa turn back to their pace spearhead Dale Steyn (and his mad, staring eyes). Elliott, who's getting a litlte bottled up at times, brings up the fifty partnership with a well-run three to deep extra cover. 99 more needed from 78 balls - 13 overs left, and Steyn can only bowl four.
"Ideally, South Africa want Anderson out. They don't want to have to bowl at him during the powerplay overs."

"How are your nerves? Eden Park is alive once more, awoken by the spirit of Corey Anderson. For the first time in a little while, you feel the momentum is with New Zealand. The Auckland crowd knows it too."
NZ 196-4 (target 298 from 43 overs)
For the first time in this innings, we have spin at both ends as off-spinner JP Duminy returns. A lot of beards on show in this game... While Duminy boosts the score with a wide, his fifth over only yields four singles and a two until a knee-high full toss - shades of Steve Smith's bowling - is hammered for an 82m six over the bowler's head by Anderson. A much better over for the co-hosts.
"Only a couple of batsmen have been able to pick Imran Tahir in this World Cup. He is bowling with so much variety."
Listen to Test Match Special commentary via the audio icon.
NZ 183-4 (Tahir 7-1-21-0)
Tahir bounces in, Corey Anderson - briefly the holder of the fastest ODI century title - doesn't look like he's dealing too well with the leg-spinner, only four singles are possible from the over - leaving the co-hosts needing 116 from 15 overs (90 balls).

Jay: I'm amazed that people are writing off New Zealand. If they don't lose a wicket for four overs, I can see the South Africans panicking.
NZ 179-4 (target 298 from 43 overs)
The 12th men and the giants drinks bottle flee Eden Park, where South Africa have had a "huddle" and an intense pep-talk from captain AB de Villiers. Philander to bowl his eighth over - under the reduced-overs formula, no-one can bowl more than nine. Grant Elliott - born in South Africa, lest we forget - is getting a little bogged down at times, but waits to thread a four through the covers. A single off the last ball takes him to 25 from 28 balls... but with a required rate of nearly 7.5, he will have to get a shift on at some point.
"It is still in the balance this game, but I think the pendulum is now swinging towards South Africa."
Drinks break
NZ 174-4
With the pacemen rotated at one end (Philander now with 0-47 from seven), the two spinners have been operating from the other end. Imran Tahir is back on in place of Duminy, he's quickly through his over and puts the brakes on with just a single from it. The players have earned some drinks - New Zealand need 124 from 17 overs.

Mark Pownall: Can't see New Zealand coming back from this now
#RugbyLI: Huge wicket for the Proteas, Taylor gone. Gonna be tough for NZ now from here I reckon.
NZ 173-4 (target 298 from 43 overs)
Anderson, who you can imagine as a burly woodcutter wielding a giant axe, again finds Philander difficult to get away for the first four balls - but then heaves a two towards cow corner, and then one swing of his mighty forearms later, a shorter delivery is hoisted into the crowd behind mid-wicket for six.
We'd normally be at the halfway mark of the innings here - but if you weren't with us for the long rain delay earlier, this is now a 43-over game with Duckworth and Lewis having set New Zealand 298 to win.
"If New Zealand keep their wickets they will win this game."

Richie O'HaraBeamand: With that wicket South Africa become favourites and we can drop the question of 'can they perform under pressure', battled back into this.
NZ 165-4 (Elliott 19*, Anderson 10*)
Elliott adds a single to bring the left-handed Anderson on strike against Duminy's off-spin. South Africa crowd him with a leg slip and a silly point, but Anderson fluently sweeps for four. A single takes him into double figures. The right-handed Elliott also powerfully sweeps for four, bisecting short fine leg and the man on the square leg boundary. 10 from the over.

New Zealand wicketkeeper Luke Ronchi: Amazing. What a game of cricket. So happy.
Review of the day - part two
Captain Brendon McCullum, as he does so often, gave New Zealand impetus with a characteristically pugnacious 59 from 26 balls. Their hopes eventually rested with a century stand from Grant Elliott and Corey Anderson.
While Anderson holed out for 58, Elliott - who was born in Johannesburg and learned his cricket in South Africa before moving to New Zealand - saw the Black Caps home with an unbeaten 84 from 73 balls.
In a thrilling finish, Elliott launched Dale Steyn, the world's premier fast bowler, for six into the stand from the penultimate ball of the match to book their place in Sunday's final, leaving a couple of South Africa players in tears.

Former South Africa all-rounder Jacques Kallis: What a great game of cricket. SA did not lose that game. NZ won it. Well played NZ. And to the Proteas you can be proud of your campaign.
Review of the day - part one
It all began just under 10 hours ago when South Africa walked out to bat after winning the toss. Trent Boult struck twice early on, but Faf du Plessis (82), Rilee Rossouw (39) and AB de Villiers (65 not out) took the Proteas to 216-3 from 38 overs when the rain came - which reduced the game to 43 overs per side.
David Miller then took the initiative with 49 from 18 balls to help SA post 281-5 - with New Zealand being set an adjusted target of 298 from 43 overs via the Duckworth-Lewis method.

South Africa have entertained - but fallen short. Thoughts now turn to those who might not be around at the next tournament in four years' time. Dale Steyn, for instance, will turn 36 in the summer of 2019, will he manage to get his battered body through another four years of international cricket between now and then? Hashim Amla will be 36.

Physio on. If Steyn can't finish the over... Morkel and Tahir have bowled their allocation. Three bowlers can bowl nine and two can bowl no more than eight. Philander has bowled eight. So if Steyn can't bowl, it would have to be Duminy or De Villiers.

Who to bowl? Four to go - Steyn has two, Philander, Morkel and Tahir have one apiece, while I doubt we'll see Duminy or De Villiers bowl again. It's leg-spinner Tahir who gets the nod. A Ronchi single is followed by two dot balls - 35 from 21.
NZ 262-5 (target 298 from 43 overs)
Two more singles mean it's 10 off the over. 36 from 24 balls needed, and a lot now rests on Elliott, who has 62 from 60 balls. Can Ronchi stay with him, or will it be the fairytale ending for old man Vettori to come in and hit the winning runs?

Emmanuel Kamara: A great game. New Zealand vs South Africa. Nerves will definitely go up for the last few overs but guess they can handle it.
Mark Kelly: That wicket helps but it changes nothing. SA still need to take another one otherwise 46 in 30 is do-able.
NZ 254-5
De Villiers to bowl the last "part-time" over, and Elliott adds a single to bring the new man Luke Ronchi on strike. Wicket-to-wicket from De Villiers, Ronchi steers him down the ground for a single to long-on. 44 from 27 balls.

WICKET
Anderson c Du Plessis b Morkel 58 (NZ 252-4)
And South Africa finally break the partnership - having dried up the runs with dot balls, Morkel fires in a bouncer which Anderson sends sailing into the stratosphere and there's snow on it by the time Faf du Plessis takes the catch. Or does he? There's a heart-rending couple of minutes while the umpires look at the replays - did the ball hit the wires of Spidercam? Apparently not - Anderson has to go.
The stadium DJ plays Michael Jackson's "Thriller". 46 from 30 balls? I'd call that a thriller. But it may be "close to midnight" by the time this game finishes...

"The highest successful run chase in any World Cup knockout game is the 289-4 Australia scored to beat New Zealand by six wickets in the quarter-final in Madras in 1996."
NZ 252-4
Tahir off, Morkel on as the skipper shuffles his front-line bowlers. With the game ebbing and flowing with nearly every delivery, the crowd is silenced after the Kiwis only manage a single off the first half of the over.

"It has been a very good partnership. New Zealand were in all kinds of trouble when Anderson came out to bat. They have worked it methodically to put themselves into this position. I'm enjoying this contest."
Appeal - not out
NZ 251-4
ABDV needs to find two more fifth-bowler overs from somewhere - so he comes back on himself. There's an appeal for leg before as Elliott tries to swing across the line - it looked quite high, and South Africa have no reviews left.
De Villiers fervently wipes the ball with a towel between deliveries as New Zealand keep plugging away with singles, but his last ball is too loose down the leg side and Anderson smashes it away for four through fine leg to bring up the century stand. 47 needed from 36 balls. Who's your money on?

Elliott 50
NZ 243-4 (target 298 from 43 overs)
And now it's Elliott's turn to reach his half-century from a slightly slower 53 balls, lofting a four over extra cover. New Zealand are rather getting after Tahir here, and there is a feeling that the pendulum has swung Kiwi-wards. They need 55 from 42 balls.

NZ 237-4
It looks like South Africa want the ball changed - a tactic TMS legend Henry Blofeld refers to as "ballsmanship". After a brief visit from the fourth umpire and his attache-case full of additional spheres, the Proteas are told to get on with it. Imran Tahir back into the attack, but Anderson is in the zone now, smacking Tahir for a four square of the wicket before bringing up his fourth ODI fifty from 47 balls.

"We are in for a nail-biter here. New Zealand need a big over. With two set batters you can get seven, eight, nine, 10 an over."
NZ 219-4 (Steyn 7-0-59-0)
Steyn to continue for his seventh over - he's allowed a maximum of nine today. Both sides are showing signs of nerves, whether running between the wickets hesitantly or nearly giving away overthrows, with every single potentially crucial. Elliott drives, it's in the air - but just wide of Du Plessis at short extra cover and they come back safely for two. Another single down the ground means both batsmen have 40 - Elliott from 49 balls, Anderson from 41. New Zealand need 79 from 54 balls. You'd have to be brave to call it definitively from here.
How's stat?
Andrew Samson
BBC Test Match Special statistician
Corey Anderson is the first New Zealander to score 200 runs and take 10 wickets in a World Cup.
The others to have done this are India's Kapil Dev (1983) and Yuvraj Singh (2011), South Africa's Lance Klusener (1999), Zimbabwe's Neil Johnson (1999), Canada's John Davison (2003) and Sri Lanka's Sanath Jayasuriya (2003).
NZ 213-4 (target 298 from 43 overs)
A first-ball boundary takes some of the pressure off the batting side, and attaches it to the bowling unit. Anderson sees off the over before nicking the strike with a single.
One of these two sides will reach their first ever World Cup final today. But who will it be?

Not out
NZ 204-4
De Villiers tries to take the ball at the non-striker's end, with Elliott nowhere. But he drops the ball and knocks the bails off with his hand. Knowing that, as per the laws of cricket, he then has to pull up a stump, he overbalances and Anderson gets back.

NZ 203-4 (target 298 from 43 overs)
Captain AB de Villiers to bowl - can his gentle medium pace be a partnership-breaker, or just smuggle through an over or two to help Duminy complete his allocation? Elliott clips a single off his legs to take his side's score to 200. With no pace on the ball, New Zealand have to do the hard yards to work it around - four from the over pushes the required rate up to the verge of eight.
And would you believe, on Duckworth-Lewis... the scores right now are nearly exactly level. While we don't anticipate more rain, it's a good guide as to who's on top.

NZ 196-4 (target 298 from 43 overs)
For the first time in this innings, we have spin at both ends as off-spinner JP Duminy returns. A lot of beards on show in this game... While Duminy boosts the score with a wide, his fifth over only yields four singles and a two until a knee-high full toss - shades of Steve Smith's bowling - is hammered for an 82m six over the bowler's head by Anderson. A much better over for the co-hosts.

The 12th men and the giants drinks bottle flee Eden Park, where South Africa have had a "huddle" and an intense pep-talk from captain AB de Villiers. Philander to bowl his eighth over - under the reduced-overs formula, no-one can bowl more than nine. Grant Elliott - born in South Africa, lest we forget - is getting a little bogged down at times, but waits to thread a four through the covers. A single off the last ball takes him to 25 from 28 balls... but with a required rate of nearly 7.5, he will have to get a shift on at some point.

With the pacemen rotated at one end (Philander now with 0-47 from seven), the two spinners have been operating from the other end. Imran Tahir is back on in place of Duminy, he's quickly through his over and puts the brakes on with just a single from it. The players have earned some drinks - New Zealand need 124 from 17 overs.

#RugbyLI: Huge wicket for the Proteas, Taylor gone. Gonna be tough for NZ now from here I reckon.
NZ 173-4 (target 298 from 43 overs)
Anderson, who you can imagine as a burly woodcutter wielding a giant axe, again finds Philander difficult to get away for the first four balls - but then heaves a two towards cow corner, and then one swing of his mighty forearms later, a shorter delivery is hoisted into the crowd behind mid-wicket for six.
We'd normally be at the halfway mark of the innings here - but if you weren't with us for the long rain delay earlier, this is now a 43-over game with Duckworth and Lewis having set New Zealand 298 to win.

Elliott adds a single to bring the left-handed Anderson on strike against Duminy's off-spin. South Africa crowd him with a leg slip and a silly point, but Anderson fluently sweeps for four.
