He also puts his teaching experience to use by writing the newsletter for Hamilton Seniornet, a computer training programme run from the Celebrating Age Centre aimed at over-55-years-olds.
Mr Kelman was a bit embarrassed at being approached by the Herald about his voluntary efforts.
"It's a bit unnecessary. You get your clothes and you get your food and that's enough for me. That's the thing about doing volunteer jobs. It's not like working for a business.
"If you say you're away for a month, you can just go and someone else covers for you.
"It comes up in the newspaper and I think, 'I wouldn't mind doing that'."
Mr Kelman also gave his time for the rowing world championships last year and the Rugby World Cup in September.
Waikato District Health Board spokeswoman Mary Anne Gill said the hours put in by the hospital's 200 volunteers were extremely helpful.
She said the shuttlebug service for which Mr Kelman is a driver is a big benefit to patients, particularly as the hospital is undergoing a $430 million redevelopment over the next 10 years.
"If we were to spend money on ferrying people around, that would be taking money out of the health bucket."
The chairman of Hamilton City Council's civic committee, Martin Gallagher, said the civic awards reflected wonderful service given to the community.
