Boxer Shane Cameron has claimed a knockout victory over American Monte Barrett.
Cameron, 34, had the more experienced Barrett, 41, on the floor just seconds into the fourth round.
"I knew that right hook was there and I set it up," Cameron said of the knockout punch.
The victory on Thursday night in Auckland means Cameron reclaims the WBO Asia Pacific heavyweight title, as well as the WBO Oriental heavyweight title.
"I said I was going to get these belts back and I did," he said.
But Barrett has said he'd welcome a rematch.
Gisborne-born Cameron went into the fight with a record of 28 wins, 21 by knockout, and two losses, including a second-round knockout defeat at the hands of David Tua in October 2009.
Cameron's build-up included a trip to London to act as sparring partner for former world champion David Haye.
Haye knocked Barrett down five times en route to a fifth-round TKO victory in November 2008, a year before claiming the WBA world belt.
The defeat takes Barrett's win-loss-draw record to 35-9-3, with one of his wins being unanimous on points over Tua last August.
