"It's like a seed is planted in them."
The eight-week programme's main goal was to engage and connect with the young people on their level.
Davis, a psychology graduate, said lessons included a shared meal and informal clinical and cultural sessions. "A lot of these young guys on the course don't always have hope. They are living lifestyles and in situations that take them around the same block again and again.
"The outcomes that we get are they have hope for the future, they know they have potential and they understand there is a purpose for their lives."
Wiremu, who did not want his last name used, joined the course despite doubting it could help him.
"I said, 'Nah, nah, I'm not a surfer.' But when I got out there the first day ... let's just say it changed my path because my old path was pretty downhill."
Davis has established the Live for More 200 Club, hoping to sign up 200 regular supporters to contribute $5 a week to keep the operation afloat.
