Scott McLaughlin became the youngest race winner in V8 Supercars history as he took his first win in a points race at Pukekohe on Saturday morning.
The 19-year-old from New Zealand had already taken victory in one of the non-championship events on the Australian Grand Prix support bill in Melbourne last month.
In the first of this weekend's four races in his homeland, McLaughlin moved forward from his fifth place on the grid as the experienced frontrunners all ran into trouble.
Fabian Coulthard, winner of five of the last seven races including the Melbourne events, lost his front row start when his top-10 shootout times were disallowed for not respecting track limits.
Polesitter and reigning champion Jamie Whincup then locked up and ran off the track with a badly flat-spotted tire on the opening lap of the race. That put the quick-starting McLaughlin second behind Ford Performance Racing's Mark Winterbottom, until the Falcon driver also had to pit with a puncture.
McLaughlin then led Garry Rogers Holden teammate Alexandre Premat in a 1-2, but the Frenchman faced a penalty for a false start and ultimately retired.
Coulthard's Brad Jones Holden partner Jason Bright – who won at Symmons Plains a week ago – kept McLaughlin under pressure to the finish, as the rookie won by just 0.8 second.
Craig Lowndes recovered from a mistake on his pole shootout lap to salvage third for Triple 8, right behind Bright.
Shane van Gisbergen and Coulthard chased them home, with Garth Tander ending up sixth after a late mistake while fighting with Lowndes.
