It appeared Dutchman Richard Verschoor would cruise to the Toyota Racing Series title but now he finds himself in a dogfight to catch Australian Thomas Randle at this weekend's finale at Manfeild.
Randle jumped in front of Verschoor in the standings after the Red Bull junior driver struggled with his car at Taupo.
"The gap is 27 now - we were in front before my crash but that happens," said Verschoor. "We will push hard this weekend and I will try everything to take those points back.
"It went really well before the last race at Hampton Downs. I lost a lot of points after the re-start there from the crash.
"The weekend after in Taupo was really bad. We still don't know what went wrong. We just didn't have the speed from the first session on.
