"Their motto is if their students fail, then they have failed," Mr Wilson said.
Mr Morrison encouraged graduates to set goals and "paddle their waka in the right direction".
"Some of the people in your waka might not be paddling and holding you back. Kick them out of your waka, you don't need them," he said.
Mr Peters told them they could achieve anything they wanted to achieve.
"It doesn't matter what your background is or what your mother, father, brothers or sisters think, if it's what you want to do and what you think is best, then do it.
"Life is not supposed to be easy, you have to work to achieve your goals," he said.
Centre manager Mericia Waqanimaravu said the next step was to find graduates work and apprenticeships.
"We are right now looking to find them placements in Auckland, Tauranga and Christchurch.
"We have a residential village in Christchurch to help with the Canterbury rebuild.
"Some have secured work here in Rotorua and the rest we are integrating into the workforce in the new year," she said.
Graduate Ratai Ratai said he gained a lot of knowledge, both theoretical and practical from the course and would soon be heading to Christchurch to take up an apprenticeship and further his building career.
"It was a lot of fun as well. I had great tutors who broke it down for us so we could all understand it," he said.
