Whanganui mayor Hamish McDouall says many local organisations benefit from volunteers - even the council.
McDouall is the latest in a series of prominent locals who are giving a few hours of their time to various organisations this week to promote volunteering.
Volunteer Whanganui's 'I Dare You' campaign coincides with international Volunteer Managers Day.
On Tuesday McDouall spent a couple of hours at Age Concern Wanganui putting address label on envelopes with other volunteers.
He said even the most boring of tasks could be made enjoyable with company.
