The centre opens again today from 5pm.
Mr Kahu said he held no grudges, mainly because he knew the young people involved and their backgrounds.
Mr Kahu said he too was like these youngsters when he was young and his life might have been different if someone had given him a chance.
Mr Kahu said: "I've been on the road where these kids are heading, gone through all the drugs and violence, the alcohol, the crime and just realised, man, if only somebody could have taken me under their wings when I was young and showed me a different way then maybe I wouldn't have gone done the path that I did."
The next step is in these youngster's hands. They have been given a massive second chance and it's up to them to use it.
It's just possible Mr Kahu's actions might light a fire in one of these youngsters' hearts to turn their life around.
