He said he does not want your money, just a donation of goods or services, including dog food for Bo or petrol vouchers for the 1971 Bedford ambulance he uses to tow his mobile barber shop.
"We have a shocking and ever-increasing suicide rate in our men, specifically in rural New Zealand, and something needs to change," he said.
"In my experience barbering overseas, no men I have come across have more trouble expressing themselves than here at home, I find that really troubling," he said.
"Life saving counselling for some men is only found in the barber's chair so we're trading our way around the country using the skills I have learnt over the years as a barber to open conversation with New Zealanders from all walks of life.
"We want to hear your stories."
Mr Haines said was supporting Mr Dowdall as it was a good cause.
"We get all sorts of people in the shop who have all sorts of life stories they want to talk about.
"Having him here will be really interesting and I hope he gets his message across."
Te Runanga o Ngati Pikiao Trust co-ordinates suicide prevention programmes in the region. Trustee Michael Naera applauded Mr Dowdall's initiative.
"It's not new that hairdressers are working with people in mental health when getting a haircut done.
"I know it's been done with ladies in the Pasifika community too.
"Some people just want to talk and hairdressers are really good listeners and people feel comfortable talking to them.
"They can help when people are in distress and can pass numbers and information on to the people they talk to.
"What a great initiative, I wish him all the best," Mr Naera said.
