Joseph Parker wins

Parker unleashes uppercut to floor Haumono

In the end, it took Parker just four rounds to land the winning blow.

After the fight, Parker said he knew straightaway he was in the ring with a motivated opponent.

"He came and gave it everything he had...he chased me around the ring and tried to land his big shot...I'm confident in what I can do in the ring.

"One piece of advice that Kev [trainer Kevin Barry] gave me in the beginning, when we first started, was in every fight, just stay calm, stay calm under pressure and when you stay calm the shots will come."
