Since 1994, Mr Edwards has helped rehabilitate accident victims with the 40-seater waka.
"I help find out what fits them - in their minds or bodies."
Being able to converse (korero) in English and te reo and the variety of everyday skills associated with the waka - maintenance, paddling, steering, haka, chants, greeting strangers, photography - all help with Mr Edwards' rehabilitation process.
"No matter how incapacitated you think you are, there's always a way around it. There's no such thing as 'can't'."
Mr Edwards started the cause when two local freezing works closed and he helped the unemployed staff to find work as carvers and weavers.
He now runs the Nga Tukemata O Kahungunu Vocational Charitable Trust, a service that teaches disabled adults to use their hands, as well as their minds, on land and water.
