But one star in particular captures our attention. The 40-year-old boxer has a star tattooed on his left hand.
There is another on his right hand but it is the left hook which has done most of the damage during a long professional career which stretches back to 1992.
And that is the punch 2.02m Russian Alexander Ustinov will have to watch out for during the pair's scheduled bout at Claudelands Arena in Hamilton on August 31.
Tua, whose records stands at 52 wins, four losses and two draws, is more of a teddy bear than a trash-talking showman type.
A softly spoken, rather humble character, he was in Dunedin yesterday, albeit briefly, to promote the fight and wanted to set the record straight.
He is not coming out of retirement. He is emerging from a self-imposed hibernation while he sorted out some ''personal stuff''.
''For me it is about the fire that still burns from within,'' Tua said.
''And just to clear things up, I didn't retire.''
Tua told a journalist he would not get back into the ring until he had those issues sorted. It was a misunderstanding. He always planned to return if it felt right.
''I know it in my heart,'' he said.
''I know I'm doing it for the right reasons.
''To have the fire and passion is one thing, but to have the right people behind you makes my job a lot easier. I can concentrate on getting myself into the best possible shape so I can go out and give the best possible performance.''
Tua has lost 20kg in the past three months and is back training with Lee Parore. He described some of the fitness sessions as ''ugly''.
It has been nearly two years since he last fought - a loss to Monte Barrett by unanimous decision - and did any serious training, so some pain was expected.
''People say I'm too old but I believe I've got great experience and that that will work in my favour.
''When I first started back with Lee ... there was a lot of punishment going on. The tough stuff that I went through was ugly - that's the only way I can explain it. But I loved it.''
Ustinov, too, is nearer twilight than dawn. The 36-year-old, 136kg former kickboxer has a professional boxing record of 27 wins and one loss.
''I'm a bit of a hulk myself,'' Tua said. The 1.78m fighter hopes to get down to the same weight (107.8kg) he was when he fought Shane Cameron.
''I've fought guys who are bigger than me throughout my career and there is something about that test where you have to fight above your weight. This fight is no different.
''What better way to test myself than against a guy who is that massive?''
Tua hungers for another shot at the title - he fought Lennox Lewis for the WBO, IBF and WBC titles in Las Vegas in 2000 and lost by unanimous decision - and a possible bout with either of the Klitschko brothers, Wladimir and Vitali. Perhaps that is why he has chosen such a big opponent. But Tua is also realistic.
He is aware an opportunity to fight for a title might be out of reach.
Another in the Duco Events stable of fighters has more time on his side. Promising boxer Joseph Parker, who recently dispatched Francois Botha, is in many respects following Tua's path. Tua had some simple advice for the 21-year-old.
''Follow your heart no matter what you do. Use that as a base for decisions you need to make for your career and don't be afraid to ask for help.''
