Joseph Parker's manager, David Higgins, is predicting a retirement party for upcoming opponent Derek Chisora.
The crossroads clash will take place on May 1, live on DAZN and Sky Sports Box Office.
Parker, a former WBO heavyweight champion, could be a win away from placing himself in position to challenge for some form of world title, according to promoter Eddie Hearn.
Chisora is coming off a very competitive twelve round decision loss to Oleksandr Usyk from last October.
Earlier this year, Parker won a tougher than expected decision over New Zealand rival Junior Fa.
While Higgins respects the punching power of Chisora, he predicts the end of the road is coming for the British veteran.
"On his day, he [Chisora] can show up and knock someone out, like he did against Carlos Takam and so we've always got to be wary of that," Higgins told the Ringside Toe 2 Toe podcast.
"But provided that Joseph Parker does not make a silly mistake, and executes his game-plan, then I see him retiring Derek Chisora. I'm not sure what David Haye does, besides managing Chisora, and so because I like the bloke I might offer him a job with Duco Events. David Haye is welcome to come and work here in New Zealand, for me, after the fight."
But rival manager David Haye has warned that Parker could be on the receiving end of a punishing assault if he engages Chisora at close quarters.
Both fighters will enter the ring with new trainers - and both are former world champions. Chisora will bring Buddy McGirt, while Parker is working with Andy Lee.
Higgins is not concerned, reflecting back on when McGirt was the head trainer for Monte Barrett, who lost hard against Shane Cameron in Auckland.
"I hope it's a better camp, this time with Chisora," said Higgins. "Nothing against Buddy McGirt, but I think Buddy would agree that the whole Monte Barrett camp was an utter shambles that ended in disaster.
"I hope Chisora has made the right decision with Buddy and I hope they are training hard and well, because we're certainly in a good space."
