Two-time former American cross country champion Paul Whibley (Pahiatua) is also a possible starter on Sunday.
The Bel-Ray Cross Country series has long been popular with New Zealand riders, with the course generally featuring safe and free-flowing trails.
The expert class has always attracted New Zealand's top talent with many Kiwi internationals competing while at home during the international off-season.
The venue for Sunday's race is Vining's Farm, Tiko Tiko Rd, west of Huntly.
The remaining two rounds are set for January 11 (Smith's Farm, Naike) and February 8 (Sutton's Farm, Bombay).
The 90-minute junior race starts at 10am on Sunday and the two-hour senior race blasts off at about midday.
Mini bike riders will run a race on a separate, extended motocross track, starting at 10am. Day licences are available and free for the first round.
Wellington's Jake Whitaker, Napier's Warren Laugesen and Auckland's Liam Draper are also fancied to be among the leading riders this weekend.
