The Hawke's Bay event was billed as the "Over the Top Hard Enduro" and, despite the ominous "extreme" and "over the top" connotations, it attracted a large number of riders, from as far south as Christchurch, as far west as New Plymouth and as far north as Kaukapakapa.
Motorcycling New Zealand enduro commissioner Justin Stevenson said this indicated how strong and healthy the sport was and how popular these more difficult events were, the extra challenge obviously having widespread appeal.
"It was a wonderful weekend of racing. The heat took its toll on a few of the riders, but the courses were brilliant and the host Hawke's Bay Motorcycle Club did a fantastic job.
"A lot of people drove a long way to be here, which just shows how popular the event is," Stevenson added.
Whitaker continues to lead the Gold Class overall after three rounds, improving from two points to be four ahead of Buxton, with Parker five points further back in third. Wiig did not contest the series opener and will not be racing at the final, so he has no chance of taking the silverware this season.
In the Silver Class, Aucklander Mark Galbraith won the weekend overall, but this was his first appearance in the series and so he does not feature among the title contenders.
Instead, it is Hastings rider Brett Gunson, who finished fourth overall at the weekend, who leads the Silver Class after three rounds, just ahead of New Plymouth duo Daniel Herbert, who was runner-up to Galbraith in this class at the weekend, and Mark Horwell.
Rerewhakaaitu's Zach Sefuiva has moved up from third to first overall in the Bronze Class, thanks to his strong performances in Hawke's Bay, with Kaukapakapa's Lucia Oles in first-equal position and Whitecliffs' rider Luke Corson holding on to third place overall despite not contesting round one.
Just as it did for last year's inaugural extreme series, the competition will again wrap up with another double-header weekend, at the two-day Nut Buster Hard Enduro at Oxford, near Christchurch, on November 15 and 16.
Only three of the four rounds of the Yamaha NZ Extreme Off-road Championship are to be counted, with riders to discard their one worst score from the three North Island rounds.
