David Tua's comeback remains very much alive after a hard fought win but deserved points decision over Friday Ahu-nanya in Auckland last night.

Tua got good rewards for being the constant aggressor in the fight although he couldn't land his trademark knockout with Ahu-nanya fulfilling his promise of durability.

Tua landed constant shots although struggled to get through the tight defence of the big Nigerian for the killer blow.

The card gave it to Tua 109 119, 111 117 and 108 120 for a unanimous decision.

Tua holds on to his WBO Asia Pacific and Oriental heavyweight belts.

This was seen as a dangerous fight for Tua but he was rarely troubled.

He was busy throughout, he went hunting Ahunanya and he ultimately gained a comfortable win.

This was a clean fight with Australian referee Gary Dean reduced to being another spectator at the sold out venue at Trusts Stadium.

Tua might be disappointed at failing to floor his opponent but his corner had spoken of the value of getting some rounds in, and he certainly got that.
