"I'm bloody pumped, I can't believe it to be honest with you. It is has been a big few weeks of haters and speculation but, hey, we are here and we have done it and proved all the haters wrong."
He said he rated their semifinal race against defending champs Rotorua as their most important race of the night, which set them up for the win.
"I was treating that as the final, that was my final race. I was ready to wreck my car, wreck everything I had including myself and once we won it I was over the moon."
By winning the event, it means Gisborne will host the teams champs next year.
"It will be good to host it and hopefully we can rustle a few feathers and win it again next year," Rees said.
Rees' dad and younger brother were also racing in the Gisborne team which won the national title. The winning Gisborne team included Asher, Bruce Harding, Peter Rees, James Kirk, Brett Lloyd, and Ethan Rees.
Each team were allowed six drivers in a team, with four taking part in each race. From the quarter-finals onwards, the format of the racing saw the team who had a driver cross the finish line first progress.
The stockcar event did not finish without controversy in the knockout stages.
In the semifinal between Wellington and Canterbury, Canterbury won the race but were later disqualified because one of their drivers had gone over the pole line then illegally interfered with the lead driver.
It meant Wellington went on to challenge in the final, but they were no match for Gisborne.
The Rotorua team that raced at the weekend included Steve Gray, Dale Stewart, Brent Stewart, Shannon Orr, Damian Orr, and Nick Johnston.
Canterbury defeated Rotorua to grab third place.
