"I know it's still a long way to go, but I feel confident I can win the title.
"There are a few small things I need to work on and, if I can find a couple of seconds per lap somewhere, I'll be right there," he said.
Chase's first senior campaign was when he tackled the 125cc class in 2013, impressively settling for fourth overall on that debut season.
He unfortunately broke his arm when he crashed at Tokoroa during his debut MX2 (250cc) class campaign last season and this year he has switched back to the 125cc class and tasted immediate success.
He has numerous junior crowns to his credit, including winning the 15-16 years' 125cc title in 2013 and the 14-16 years' 250cc title in 2014.
Chase has enormous experience at the ultimate level of the sport, having also raced in Australia - where he finished fourth in the junior national 250cc class last year - and in New Caledonia and Belgium as well.
The New Zealand Motocross Championship series continues at Timaru on February 22, with rounds to follow at Rotorua (March 8) and Pukekohe (March 15).
