As her hair was being cut, Ms Overton-Stuart was remembering those who had battled blood diseases.
Her grandfather died of leukaemia and other family members had suffered from blood cancers.
"I was thinking of those loved ones who have battled cancer and lost, and all my friends and whanau who are currently challenged with this," she said.
Donations can still be made and those wanting to support the two women should go to www.shaveforacure.co.nz and search for PAUA Team. Alternatively, there is a donations bucket at PAUA Products, 9 Park Place, where the hair-cutting took place.
And Ms Overton-Stuart may not have yet escaped the razor blade.
"If a mystery benefactor takes our total past $10,000, I will still have the full blade shave," she said.
