On Sunday there are two races planned, a two-hour endurance race for Pro Twin 650cc riders, Junior Bears (non-Japanese) bikes, Formula Three and 300cc production bikes, followed by a three-hour endurance race for Formula One, Formula Two (600cc) and Senior Bears riders.
Cash and prizes, not to mention bragging rights, are at stake.
Aside from Rees, other high-profile riders expected to make the trip include his two sons, current national superbike No 2 Mitch and former national 600cc champion Damon, former Superbike World Championship contender Aaron Slight, nine-time national superbike champion Andrew Stroud, Wellington's 2018 national superbike champion Sloan Frost, Taupo's national superbike title contender Scotty Moir, former national 600cc frontrunners Daniel Mettam and Toby Summers, and former national superbike champion Chris Haldane, among others.
"It's going to be a fun weekend and that's the point of this really," said Rees.
"There will be a lot of fast riders coming, but it's not really about them.
"It's also a good chance to have a big hit-out before the national superbike championship season kicks off and so that's another reason these top riders are coming."
