Bachelor star eyes winning form for bout

Zac Guildford will be taking part in the Fight for Life against bachelor Art Green.

The man made famous throughout New Zealand as the ultimate romantic says he wants to show he can be both a lover and a fighter when he enters the boxing ring with a rugby player.

Art Green, star of The Bachelor NZ, will be going head-to-head with Hawke's Bay rugby star Zac Guildford at this year's Fight for Life.

Green said he had never been in a fight before. "I've always thought of myself as a lover not a fighter, but hopefully I'm going to prove myself to be a lover and a fighter."

At 189cm, Green has the height and reach advantage over Guildford but admitted when he heard who his opponent would be he was nervous.

"I was actually pretty reluctant to take the fight," he said.

Green has been training with boxer and former rugby league player Monty Betham.

"[Betham] gave me a bit of confidence and faith that we'd be ready to the point that I could take [Guildford] on and win."

The charity fight night aims to raise $100,000 for Waikato Hospice and Green said the charity aspect, as well as the fitness, drew him to the event.

"Whether I lose in the ring I still win in the end," he said.

Guildford said he did not watch The Bachelor NZ but was aware of the show through social media while he was playing rugby for French club Clermont Auvergne.

He said when he returned to New Zealand he was overweight, and since training with Ryan Whittaker at Napier Boxing had lost 6-7kg.

"I've been asked a lot in the past and I've said no.

"But coming back from France it gave me a focus ... that would make me better as a person and as a rugby player.

"It'll make me fitter, stronger and mentally tougher."

Guildford said the fight was "daunting" and the training so far had been tough.

"It's been bloody hard so far and it's not going to get any easier.

"The footwork and stuff ... I'm not the best dancer in the world, but it does feel like you're on the dance floor sometimes."

Guildford agreed rugby players were often considered to have a bit of "mongrel" and said he wouldn't be "folding over" in the ring.

The charity fight night will be held at Hamilton's Claudelands Arena on December 5. Also entering the ring is netball great Irene van Dyk, whose opponent for the event has not been confirmed.
