"Ross is coming back again and Tristan [Teki] has got his new entry.
"We've got a few other of competition cars lining up for everybody.

Gerald Smith will be bringing over one of his dragsters from Palmerston North, while Rivers and his son Adrian of the River Rat team have been getting their NZ1 Blu's Brothers car from last season ready for an exhibition of supercharged and fuel injected Pontiac power.
"We put the engine on the car last night, then set up to run it in," Rivers said.
"We got it ready for another [run] for the nationals."
