"MX1 is more international and MX2 is really where it's at in terms of New Zealand motocross talent," says Broxholme.
He identifies veteran Darryll King (Hamilton) and defending champion Scott Columb (Queenstown) - both on Yamahas - along with Honda's John Phillips (Rotorua) as likely contenders.
"And there are a few young guys coming through as well like Kayne Lamont [Husqvarna] and Hamish Dobbyn [KTM] on the 250cc 2-strokes. It's going to be a battle."
Yamaha will provide the international flavour in MX2 with Australian under-19 supercross champion Jay Wilson joining the field. Broxholme says he's looking to improve on his early season results.
