Shane Cameron will return to boxing with a heavyweight bout against veteran Kali Meehan in November.
The pair will be the main event of the next Super 8 tournament, which will feature cruiserweights, and will take place at the North Shore Events Centre.
Cameron (29-4) hasn't been in the ring since he lost to American Brian Minto via TKO in December but feels he has a point to prove on November 22.
"I refuse to resign my legacy to the Minto bout," Cameron said. "I underestimated him and wasn't fully prepared, boxing is a harsh mistress when you don't treat her with respect.
"I won't make the same mistake with Kali, I'm taking this fight because I believe I can win and get my career back on track."
Meehan, who won the inaugural Super 8 heavyweight crown in June, has a 41-5 career record and has fought around the world.
Cameron's manager, Ken Reinsfield, was adamant Cameron had the skill and mental toughness to topple Meehan.
"Shane could have taken an easy fight, but that's not his style, he's made a career of taking the toughest fights available and that's what makes him the Mountain Warrior.
"Shane relishes the underdog tag and is highly motivated - don't forget what he did to Monte Barrett when most people wrote him off.
"Styles make fights, Shane likes to come forward and has a proven history of dismantling taller fighters and Kali is 6 foot 5 and doesn't like being pressured on the inside.
"Kali knocked out Michael Sprott who beat Brian Minto, so beating Meehan will prove December was simply a bad night at the office."
New Zealand's top-ranked fighter, David Aloua, will also will defend his WBA Pan African and WBO Asia Pacific cruiserweight crowns against Aussie world No 14, Daniel Baff in the co-main event.
The Super 8 competitors are expected to be announced this week.
Meanwhile, Israel Adesanya won last night's King in the Ring cruiserweight kickboxing tournament in Auckland.
Adesanya, who will make a return to the Glory promotion later this year, beat Jamie Eades in the final to claim the crown.
Papamoa's Faith Van Duin lost her Storm Damage featherweight MMA title in Canberra last night after going down via TKO to Arlene Blencowe in the third round. It was Van Duin's first loss of her professional career.
