Bundy the Barber aims to break a world record with eight hours of free haircuts in Britomart.

An Auckland barber is believed to have achieved a Guinness World Record by performing hundreds of free haircuts.

Barber Brendan Blake, who prefers to be called Bundy, and his team of nine barbers cut 396 heads of hair between 8.30am and 4.30pm at Auckland's Britomart Country Club on Friday, beating the current record of 375 haircuts in eight hours.

The record attempt was designed to raise awareness for Movember - a month-long men's health campaign held annually in November.

Bundy opened his first barbershop, Boar and Blade in 2012 on Egmont St in Wellington with limited finances.

Soon after opening he was diagnosed with testicular cancer.

CHRIS MCKEEN/FAIRFAX NZ Brendan Blake (aka Bundy the Barber) is attempting to set a record for the most barber haircuts in one day to raise funds for Movember.

"When hear you have the c word, it hits you like you've just been in a car accident," Bundy says.

"I trucked on through, I got diagnosed on the Monday and I was in emergency surgery on the Friday.

"I had to go back to work and clients would send me home because I was in so much pain but it kept my business alive."

Bundy says he was shocked when the doctor showed him his scans.

"The whole testicle had a big tumour in it and was full-blown cancer."

He has been a supporter of Movember for years and knows the importance of checking on your friends.

"Go in once a year and get a check up, talk with your mates about it and check in on them too."

Movember country manager Robert Dunne says Bundy has got amazing stamina and a positive energy which will carry him through the hair cutting record attempt.

"We're proud to support him and the team through this massive challenge," Dunne says.
