David Tua has ended his pursuit of another shot at a world heavyweight title, announcing his retirement from boxing after losing to Belarusian Alexander Ustinov by unanimous decision.
The 2.02-metre Ustinov used his height and reach advantage to good effect to keep his opponent at bay and control the 12-round contest in Hamilton.
Afterwards, Tua told the crowd he would be hanging up his gloves.
He said he had got himself in great shape for the fight because he believed he could still do the business.
"I believed that the fire still burns but, after tonight, I'm sad to say but my heart is not in it any more," he said.
"It's time for me to try something different."
Tua, who turns 41 this week, thanked the New Zealand public and the Pacific Island community for their support.
He said there would be two people who would be happy with his decision to retire - "my mum and dad".
The loss was Tua's second in a row and he ends with a record of 52 wins (43 by knock-out), five losses and two draws.
During a 21-year professional career, he fought some of the big names in the division and had one world title challenge, losing to Briton Lennox Lewis by unanimous decision in 2000.
In beating Tua, the 36-year-old Ustinov took his record to 29-1-0.
