Gaze has also returned to top form after early-season illness to finish second behind Cooper in the latest round of the Swiss Cup, pushing World and Olympic Champion Nino Shurter back to third.
The team include a powerful contingent of downhill professionals led by world No 22 George Brannigan and fellow Hawke's Bay professional Brook MacDonald, currently ranked 32nd.
There is also considerable reward for riders from the MTB National Performance Hub, established last year by Cycling New Zealand, with 11 of the squad selected for the world championships after impressive form in Europe so far this season.
Australia last staged the world championships in 2009 in Canberra while Cairns hosted the UCI World Cup in 2014 and 2016 at the famed Smithfield Regional Park just north of the city.
