David Tua's remarkable transformation is complete ahead of his heavyweight boxing fight against Alexander Ustinov in Waikato tonight.

Tua has weighed in at 107.5kgs after he reportedly lost over 50 kilograms since he started training to fight the seven foot Belarusian.

Ustinov has weighed in at 132.9 kilos, for a weight advantage of more than 25kgs and has won 28 of his 29 professional fights.

Adding to the sense of occasion is the sudden introduction of the WBA Pan African belt which will be for the winner.

Meanwhile Fiji's light heavy weight boxer Isaia Junior Maku will fight Sam Rapira a Maori who is also known as the terror in one of the supporting bouts tonight at 9pm.
