Courtney said she first considered the shave last year when colleagues took part in the fundraiser.
"I thought it was a cool and it goes to a good cause," she said.
So this year Courtney told her colleague that if he raised more than $380 she would shave her hair.
"Of course he did and now I'm here holding my hair," she said.
"I don't really have a sob story but it really is a good cause."

Lily Cameron, 17, said having her head shaved wasn't a difficult decision to make.
"Everyone has family members who have had cancer," she said.

Cameron aimed to raise $500 but smashed her goal out of the park by raising more than $1200 and counting.
"It's always good to be able to give something to a cause that needs money and if you can be charitable then why don't you?"

The money helps Leukaemia and Blood Cancer NZ pay for patient support, research, information and advocacy. It gets no government funding.
