However, under the rules of super moto racing, riders are not permitted to rejoin the race after crashing and so Dibben was disqualified, adding controversy to the contest because Hart had not been disqualified for rejoining after his spill at Hampton Downs a week earlier.
The two-race tracks are very different and riders disappear from view in several parts of Hampton Downs, Hart's crash going largely unnoticed, while the open-plan nature of Manfeild meant Dibben had nowhere to hide.
The Hampton Downs incident involving Hart was not picked up within the 20-minute time-frame allowed for protests and he therefore escaped any penalty.
"Exactly the same thing happened last year when Richard Dibben crashed at Hampton Downs and it wasn't spotted by the officials. It went in his favour on that occasion," Hart explained.
So, with it being a case "swings and roundabouts", Hart now finds himself with a nine-point lead over Aden Brown of Wanganui.
"I love racing at Wanganui. I was 10 points behind Richard (Dibben) heading into Wanganui in 2012 and, even though I qualified fastest and won both of the races that day, I eventually missed out on the title by two points.
"I couldn't contest the whole series last year because of injury, so to be leading the series going to the final round this year is fantastic for me."
