New Zealand heavyweight Joseph Parker barely broke a sweat when defeating American Daniel Martz by TKO in Hamilton tonight.

Parker's unblemished record, which now stands at 17-0 with 15 knockouts, was hardly put to the test as he ended the fight with a right cross that landed flush to the side of Martz's head just under two minutes into the first round.

The 2.03m Martz (14-2-1) - nicknamed 'The Mountain' - is the tallest opponent Parker has faced and bravely rose from the canvas to beat the count but was clearly unable to continue on wobbly legs.

It was the perfect finish to a night that marked Parker's rise to 10th in IBF heavyweight rankings, with promoter Dean Lonergan insisting a highly anticipated world title bout could be locked in as early as July.

"Joseph Parker today went to number 10 in the IBF," Longergan said. "That's fascinating because Tyson Fury will throw in the belt for the IBF.

"Vyacheslav Glazkov, who's the current number one, will fight Charles Martin and very soon we could be in that number one to be fighting for the heavyweight title of the world in the IBF.

"The actual fight will take some time to get but we can get there in eight months."

After his fifth win of in 2015 - after also knocking out American Jason Pettaway, German Yakup Saglam, Bowie Tupou and Khali Meehan – Parker didn't hide his desire to take on the current world champion Tyson Fury but insisted he's in no rush.

"I'm happy that all these guys support me and think that I'm ready for it, I know I've still got a lot to work on," Parker said.

"But we're not too far behind. I think with the plan we have in plac we can get there very soon."

The win saw Parker retain his four belts ahead of his next matchup against American Jason Bergman (25-11-2) in Samoa in January.
