In his second heat Barnett rolled clubmate Regan Penn in spectacular fashion and in his final race of the weekend Barnett rolled Wanganui visitor Chet Swan.
The Rotorua Rascals became the first back-to-back winners in the six-season history of the event when they beat the Auckland Alley Cats in the final. With their loss the Alley Cats missed out on a fourth trophy for the season as they had earlier won the national title and the Huntly and Kihi Kihi teams events.
Callum Flavell, who was making his Peter Barry meeting debut for the Rascals, provided an anxious moment for his manager and former Bay of Plenty rugby lock Steve Axtens, when he came to a halt a metre from the finish line. Fortuntely a teammate was able to nudge him across the line to secure the victory and one of the heaviest trophies in Hawke's Bay sport.
"Although we got the wins we needed we weren't on our game last night. But we stepped up tonight with some complete team efforts ... and we will be back next year with the aim of a three-peat," Axtens said as he and his drivers were smothered in congratulatory hugs and kisses.
Three of his drivers, Steve Gray, Brent Stewart and Darcy Meurant were in last year's winning team. They were joined by Flavell, Michael Rumney and Richard Keijzer for the weekend.
Only four of the 12 starters finished the action-packed final and the Alley Cats, like the Rascals, reached the final with an unbeaten run.
Alley Cats manager Geoff Cook said he was disappointed his troops could win the title for the first time but pointed out it wasn't through a lack of effort. He was hopeful the same team will be available to attempt to go one place better next year.
Rotorua's Dylan Towler won the 39-car David Jones Motors Gold Cup for Ministocks which was the other feature attraction during the two nights. With three wins and a second in his heats Towler was the hot favourite going into the 12-lap top 26 final which he won by four seconds despite starting grom grid 11.
The winner of the prestigious Ministocks in Paradise event on his home track last month, Towler, also set a new track lap record for his class of 19.8431s on lap five. Kihi Kihi's Dion Henderson was second and Palmerston North's Nicole Hickmott third.
Lauren Swift was the best of the Hawke's Bay finishers with a sixth.
