Three goals in two first-half minutes got Newtonmore's bid for a seventh consecutive Marine Harvest Premiership title off to a roaring start as they put Glenurquhart to the sword 7-0 at the Eilan.
Glen MacKintosh and Iain Robinson scored hat-tricks as More, one of four Premiership sides starting their season after opening-day postponements, ran riot against the Drumnadrochit side.
However, there was less joy for Camanachd Cup holders Lovat who began with a 5-2 league defeat at home to Kinlochshiel. All of Shiel's goals came from players called MacRae, a surname synonymous with the Wester Ross club.
Skye made their belated return to the Premiership with a one-all draw away to Lochaber while Kingussie edged Fort William 1-0 at the Dell.
MacKintosh opened the floodgates for Newtonmore midway through the first half and within two minutes Robinson made it 2-0 and MacKintosh got their third.
As half-time approached the score leapt again to 5-0 when MacKintosh completed his hat-trick and Evan Menzies also got on the score sheet. Robinson then got two more in the second half to complete the eclipse of a Glenurquhart team which won the MacTavish Cup and finished third in the Premiership in 2015 but has now conceded 10 in two opening games.
It started well for Lovat at Balgate when Lewis Tawse gave them the lead. Finlay MacRae equalised but Kevin Bartlett put Lovat ahead once more before Keith MacRae tied it up again just before half time.
However, the second-half goals were all Shiel's and Keith MacRae completed his double in between a similar contribution from John MacRae.
Skye had to come from behind for their point on their return to the top flight. Stuart Callison opened for Lochaber midway through the first half before Jordan Murchison got Skye's equaliser just after the hour.
And in the early throw up at the Dell, Thomas Borthwick got the only goal for Kingussie in the first half.
Inveraray, just relegated from the Premiership, again showed that they could even find life difficult in the National Division.
Having earlier failed to find the net against Bute who were previously playing third-tier shinty, Inveraray found themselves on the wrong end of a 6-2 thumping at Beauly.
Grant Griffin and Lewis Montgomery put Inveraray ahead but they had no answer to five goals from Jack MacDonald before Conor Ross completed the job.
Caberfeidh had a 4-1 home win over Inverness who scored first while a 4-0 win for Glasgow Mid Argyll completed the National Division programme.
