Boxing: Daniel Martz not here to provide practice for Joseph Parker

American boxer Daniel Martz has warned Joseph Parker that he's not here to provide practice for the unbeaten Kiwi heavyweight at Saturday's Fight for Life event in Hamilton.

The 2.03m Martz (14-2-1) - nicknamed 'The Mountain' - is the tallest fighter Parker has faced in his 16 fight career since 2012.

While he understands he has been enlisted to further Parker's development and help prepare him for fights against bigger and taller opponents, the 25-year-old brawler from Clarksburg, West Virginia has no interest in being a mere stepping stone on his journey to a title challenge.

"I don't feel like I'm practice. I'm a lot more than practice and on Saturday night everybody's going to see that," Martz said.

"I'm going to push him around. I'm going to try to use my size to my advantage."

Martz packs a big right hand jab and arrived in Auckland on Sunday brimming with confidence after a productive month-long training camp in Russia with former world champion Alexander Povetkin.

While not dismissive of Parker's record (16 wins, 14 knockouts), he believes his past opponents have lacked the ability to really test him, and says his own rugged and uncompromising style will hold him in good stead.

"He's fought some good fighters but fighters that were past their prime. I'm big, I'm strong, I'm going to make it a rough fight," he said.

"He's got really fast hands, he's got good footwork, but that's one of the things for a good boxer that's the hardest to deal with, is someone that's coming in there and brawling.

"They're used to fighting and training with other good boxers, but I don't plan to do that. I plan to go in there and make it a tough street fight."

Tyson Fury's stunning upset victory over Wladimir Klitschko on Sunday has heightened expectations around when Parker might be able to land a title challenge, but Martz rates himself up there alongside the best in the division.

"I'm right up there with them all. I just sparred (40 rounds) with the number one ranked contender (Povetkin) in the world and I did very well with him and I'm right up there with all of the rest of them."
