"All of them want to come back and we're putting together another six-week course that could be based around motorcycle and other small motors."
Mr Morunga said the training agency would keep "building on what we know" and was looking to consolidate partnerships with the Maori health providers Whaiora "and its Whanau Ora concept" and Te Hau Ora Runanga o Wairarapa.
"We want to make sure we keep the options open for youth who have may find difficulty fitting with mainstream organisations."
The marae-based scheme aims to train mostly at-risk teens and was launched in 2009 as a New Zealand-first pilot.
