There are 15 fights on the card at Kensington Fitness Centre next Saturday including a kick-boxing match and three women's fights. Most of those involved in the charity challenge have little or no experience in the ring.
Under the watchful eye of Roundhouse owner, instructor and event organiser Simon Haenga the participants have got themselves fight fit and are ready to box off. Whitcombe reckoned the eight weeks training had been intense and demanding.
"I've developed a new respect for boxers. I've never trained like this before. I pushed myself 100 per cent for rugby training but this is a different intensity," Whitcombe said. "Hitting someone else is uncomfortable ... I probably wouldn't have said that 10 years ago. It's been a bit uncomfortable and a bit of the unknown"
But all that will change once he pulls on the gloves and steps into the spotlight in front of an enthusiastic crowd and a competitive opponent. Haenga said his charge had stepped up and developed some pretty good boxing skills.
"Derren hits like a Mac truck. I'm glad I don't have to fight him and I have every confidence he will do the business," Haenga said.
He noted most of the fighters were outside their comfort zones but were fitter, stronger, healthier and happier than they had been for a long time. There was also a camaraderie that had developed amongst them.
"They have gained in confidence and made new mates. There is nothing like battle to cement those bonds even if they have to punch them out."
Haenga said it was a privilege to organise an event that helped two great charities used by Northlanders.
Last year $7500 was raised and given to Ronald McDonald House and North Haven Hospice.
About 35 corporate tables have sold out but there is seating for another 600 at Kensington Stadium. There will be plenty of entertainment and a charity auction.
Tickets can be bought from Roundhouse in Bank St or at the door when they open at 5.30pm on the night; Saturday April 21.
