However, Whanganui's Seth Reardon, the championship runner-up in 2019, is expected to line up on Sunday, alongside Palmerston North's 2015 national champion Paul Whibley, Wairoa's Tommy Watts, Pahiatua's Charles Alabaster, Raglan's Brandon Given, Hamilton's Phil Goodwright, Hamilton's Andrew Charleston, Te Kauwhata's Jacob Brown and Rotorua's Callum Dudson, to name a few.
Napier's Reece Lister makes his return to the sport and he'll be one to watch for after his scintillating performances in the parallel-but-separate motocross championships.
Drury's Richard Sutton, Glen Murray rider Sam 'Charlie' Brown, Pukekawa's Jim Orton, Toko's Karl Roberts and Taupo's Hadleigh Knight could also be battling near the front.
Sunday's racing is set for Smith's Holly Farm, 235A Galpins Road, RD2, Marton on Sunday (February 28) with all riders knowing a good result is essential if their respective bids for glory are to bear any fruit.
Points from only the best three results from the four rounds will be counted towards the championship titles, with riders to discard their worst result. This also allows competitors the option of having to make only one trip across Cook Strait.
"The course at Marton will offer a bit of everything ... a ravine, open farmland, tight native bush, gorse and pine trees," said Motorcycling New Zealand cross country commissioner Chris Smyth.
"We have a non-championship class this year too – the Under-19 development class. This is where the riders of the future may come from," he said.
The 90-minute junior race kicks off at about 9am on Sunday, with the three-hour senior race to follow at about 11.30am.
