Netball star Erena Mikaere chopped her hair off and Black Fern Stacey Fluhler got the opportunity to do it for her.
"I'm currently nervous, I don't know how I'm going to talk as you're doing it," Erena told Stacey during Sunday evening's Te Ao Toa programme.
"I'm doing it for brain tumour awareness. I have a lot of whānau who are part of it - who have had it, who have dealt with it," she said.
"I have a friend who has just got brain tumour cancer and she started the foundation because there was no awareness around it and there's so many people who either deal with it as a family or get it and there was no information, no help.
