Heavyweight Monte Barrett has questioned David Tua's punching power as both boxers gear up for this coming Saturday's rematch in Manukau. Tua has won 43 of his 52 fights by knockout, but the big puncher has failed to score a stoppage since he destroyed Shane Cameron back in October of 2009.

When they fought in July 2010, it was Tua who got dropped for the first time in his pro career, when Barrett caught him in the twelfth and final round. The bout ended in a controversial draw with both boxers claiming robbery.

"A blind mouse can tell you that was a robbery. I'm here now for a do-over," Barrett told Stuff. "I keep hearing these things that he's going to stop me in the early rounds. Why don't you ask David about my power? I'm the one who is standing. He's the one who got dropped. I don't want to hear about David's power no more. Ask David how he felt about being dropped."
