Hart is an extraordinarily talented rider and his modified Yamaha YZ450F is obviously a very potent weapon, but luck has also played a part in putting him in the prime position again this season.
Hart has not been the quickest of the super motard competitors, that honour belonging to another former series winner, Whanganui's Richie Dibben.
But crashes and mechanical gremlins have derailed Dibben over the past few seasons, while Hart has consistently finished at or near the front.
Hart won the super motard class title in this series in 2014 and last year too, so he certainly knows how to get the job done.
"I'm not resting on my laurels. I've been racing this sport a few years now and I know anything can still happen," he said.
"I crashed during practice at Manfeild on Saturday and hurt my foot and then our first race on Sunday was red-flagged after another rider crashed, so it can be a crazy sport sometimes and it's not over yet.
"Richie (Dibben) has been extremely fast all season and I'll need to do something special to beat him at Whanganui on Boxing Day."
Hart is 12 points ahead of Bulls' rider Ashton Hughes, with Dibben in third, 3.5 points further back, and he in the perfect position to claim the series outright provided he can avoid trouble on the Cemetery Circuit on Boxing Day.
Hart is supported by Mimico, Ryco, The Equipment Centre, Endeavour Engineering and Bayride Motorcycles in Tauranga.
