He's a port worker and she's a stay-at-home mum – but don't underestimate them in the ring tomorrow night at the MTB TGA Charity Box event.

Papamoa man James Levao and Tauranga's Tiffany Rolleston are ready to clash in two of 17 bouts on offer as the event at QEII tomorrow night fights to raise funds for Wish 4 Fish Foundation, Tauranga Women's refuge and Kids Love Kai.

James will take on professional fighter Brown Butterbean from Auckland in the main event, while Tiffany fights for the first time in the undercard round.

Of 17 bouts, 16 are corporate bouts – meaning fighters have never been in the ring before.

And while James has never taken to the ring before, he's pitted against the only professional for the main event of the evening.

'I'm a bit nervous but I guess that comes with fighting someone with a bit more experience,” says the 38-year-old, who reckons he's fit and ready, with his trainer guiding him towards victory.

'But hey, I'll give anything a go.”

Tiffany's been training at a makeshift gym underneath co-organiser Jewel Pipene's Judea house.

'Half of me is keen to for it to be over while the other half is like ‘bring it on',” says Tiffany, 33, who signed up after watching last May's event.

'I took my hat off to everyone who got in the ring – and thought to have that type of courage you've got be pretty hearty.”

Pregnant at the time, Tiffany vowed to 'give it a go” after giving birth, and five months later, she's ready.

'It's definitely out of the ordinary and having a little baby makes you work really hard because you don't just want to leave her and go to training and muck around.

'You can't blame or rely on anybody else in the ring. It's just go in and have enough confidence in yourself and all your hard work will pay off – that's the plan. Winning is just a bonus.”

Her main focus is to last the three rounds and enjoy it.

Co-organiser Carla Vaetoe says fighters are Tauranga people from all walks of life.

'Our youngest is 19, with 54 our oldest,” explains Carla. 'There's builders, port workers, school teachers, mums, couriers drivers – anyone.

'We put them through a training scheme, and if they work out alright and are medically fine they fight.”

Boxers train six days weekly for 12 weeks at Jewel's house. 'We've split them into red and blue teams,” adds Carla.

'Teams come on different days so they don't see each other or their opponents until weight-in tomorrow morning.”

Tickets to tomorrow's MTB TGA Charity Box cost $40 and are available by calling Carla on: 021 240 0026. Alternatively they are $30 on the door, which open at 5.30pm at the QEII. The first bout starts at 6pm.
