"I promised to help but very clearly said I wasn't going to shave my head. But then I had an internal dilemma of how to support the cause if I wasn't going to walk the talk."
The deputy mayor said the prospect of going bald was "scary" and she would do it only if she could raise $5000 in donations.
The Bald Angels Trust was a worthy local charity but she had wider reasons for wanting to take part.
She wanted to send a message to Northland kids, by showing a lot of people cared deeply about them; and to young women, that they shouldn't let hair and clothes define who they are.
Ms McInnes she had always loved her hair, even when she didn't love the rest of herself. "For many women our hair is our crowning glory, and can also be our shield against the world. For me it's a big part of my identity.
People often recognise me by my hair," she said. The Bald Angels' first big shave three years ago raised more than $45,000.
Donations can be made to the Bald Angels Charitable Trust's Westpac account 03-0351-0240110-00.
