The newly-created GIXXER Cup class, set aside for riders aged between 14 and 21 and all on identical Suzuki GSX150F bikes, got off to a booming start.
Hamilton's Jesse Stroud, the 15-year-old son of nine-time former national superbike champion Andrew Stroud, scored back-to-back wins on Sunday.
He leads the class by 10 points from the "West Coast Warrior", 14-year-old Greymouth rider Clark Fountain, with Paeroa's Blake Ross, Taupiri's Zak Fuller and Whanganui's Ollie Dennison completing the top five.
As well as being an integral part of the three-round Suzuki Series, the GIXXER Cup grade of competition will also be a feature of the four-round 2018 New Zealand Superbike Championships, beginning at Mike Pero Motorsport Park, Christchurch, on January 6-7, with rounds to follow at Timaru, Hampton Downs and Taupo.
Riders will count six of seven rounds from these two separate competitions, discarding points from their one worst round, to determine the 2017-18 champion in this inaugural GIXXER Cup competition.
