Kidderminster kept their play-off hopes alive after coming from behind to see off struggling Darlington.
Ryan Bowman headed the Quakers into an early lead but Dave Hankin drilled in soon after to level.
Anthony Malbon gave Harriers the lead after the break after being played in by Steve Guinan and shooting low past Darlington keeper Jordan Pickford.
James Vincent then set up fellow substitute Ryan Rowe inside the box, who fired in his first Harriers goal.
VIEWS FROM THE DRESSING ROOM
Kidderminster boss Steve Burr told BBC Hereford & Worcester:
"We're still in there and it was good to get three points.
"We created a few good chances in the first half that we should've done better with but, in the end, we got the breaks in the second half and went on to win the game.
"I was pleased with Ryan Rowe to get off the mark for us with his first goal and hopefully that'll give him a big lift."
