"I like the Patetonga track ... it suits me and I usually go well there. I have been putting in a lot of hard work with JCR Yamaha Racing team boss Josh Coppins, so physically I am very prepared."
The rider who is c right behind Vaughan in the 125cc standings, Bayride BikesportNZ.com Yamaha rider Logan Blackburn, of Te Puke, will also be trying to move up and he is one rider who Vaughan must respect.
"I know Logan [Blackburn] will be fast and I have to watch out for Atiamuri's Hadleigh Knight too, although he had a rough time at Timaru and is a wee way back in the points now. "Even if Hadleigh could win one or two races, seconds or thirds would be good enough for me to take over the championship points lead.
"Logan is my biggest threat. I will try to block out thoughts of the other riders and just do my job," said Vaughan.
"I'm a big fan of the Patetonga track. I like it when there are lots of deep ruts. It is important for me to get good starts though because it's hard to pass other riders around there."
After Patetonga on Sunday, the series heads to Pukekohe.
