Likewise in class nine, northern title holder Gregg Carrington-Hogg is unchallenged and can cruise to top points in short course racing before taking on McCall for the enduro.
There's a strong family presence in the event, with Dean Graham in class three and sons Matt and Todd running in class five for cars with engines up to 1.3 litres. Dean and Todd won their respective classes at the recent NZ 1000.
The UTV class sees Ben Thomasen of Tauranga going up against a half dozen top contenders including Mike Small, Roger McKay, Joel Giddy, and drift racer Carl Ruiterman. Thomasen created history in September when he became the first UTV racer to win the flagship NZ 1000 two-day endurance race. Though the class is open to UTVs from event sponsor Polaris, Arctic Cat, Can Am and Yamaha, it is the Polaris RZR 1000 that dominates.
No other brand has yet won a race in New Zealand.
The 10-strong class three for race cars with engines up to 1.6-litres pitches southern class champion Greg Winn (Nelson) up against the new generation race cars of Brendon Midgely and Devlin Hill.
In the unlimited truck class, Christchurch driver and defending national champion Owen Chang meets a tough grid of northern and southern hopefuls and will be hoping that a comprehensive redevelopment of the GT Radial Ford Falcon turbo will fend off challenges from leading rivals Carl Gardner, Jono Climo, Donald Preston, Nick Hall and Raana Horan.
Racing gets under way tomorrow at 1960 Matapiro Road from 9.30am.
The 200km endurance race on Sunday starts at 11am.
