The event will feature dozens of races for all categories, from the mini riders aged from 4-11, on bikes as small as 50cc, to juniors, women, veterans and senior men, on bikes with engine capacities anywhere between 125cc and 450cc.
The river race set for Sunday is also a massive crowd-pleaser.
However, it is the New Zealand v Australia element of the event, the FIM Oceania Challenge Cup, which sparks much added interest and elevates it to a new level.
The Challenge Cup will feature two squads of riders nominated to represent their respective countries over the two days and the race-within-a-race element should again prove popular crowd.
The FIM Oceania aspect has enjoyed success over the past two seasons, the New Zealand contingent beat the visiting Australians in the inaugural FIM Oceania Trans-Tasman Challenge in 2018, edging them out by a solid 57 points, but the Australians fought back at the 2019 edition and beat the Kiwis to the coveted trophy, albeit winning by a solitary point.
No let-up in the rivalry is expected this time around either.
Participating riders from Australia and New Zealand have yet to be confirmed but there is no shortage of willing candidates keen to lock horns in this inspired trans-Tasman showdown.
The Manawatu Orion Motorcycle Club (MOMCC) has hosted the Woodville GP every year since its inception in 1961 and is proud to again be chosen to stage this FIM Oceania Challenge competition.
MOMCC president Fraser Miller thanked FIM Oceania for giving the club the opportunity again.
"It is a real privilege to have this status. We want to give the crowd great entertainment, something they can really get behind and there really is nothing better than the sporting rivalry that exists between Australia and New Zealand," he said.
Racing over the two days attracts thousands of spectators to the Tararua region, filling motel rooms and camping grounds to the point of overflowing, the New Zealand Motocross Grand Prix at Woodville a must-see spectacle for any motor sports enthusiast.
