"This is just the first step of a long mission, but we can do it."
The programme has been called Tu Taua and Hollingsworth said it was Te Arawa's stand against meth.
He has been clean from the drug for seven years, and began working with other users on their road to recovery.
"There are kaumātua who are worried about their mokopuna, rangatahi worried about their friends," he said.
"Healing isn't something that happens in people, it's something that can only happen between people."
Te Pae Akurangi-Fitzell, from Te Runanga o Ngāti Pikiao, said the series of wānanga was about putting the issue back to Te Arawa and asking them where to next.
"Kevin really brings something special to these hui, through the presentation and his own experience.
"There is always hope for people and that is what he has shown our whānau and our people."
Akurangi-Fitzell said they had opened the invitation to attend to all people, from rangatahi to kaumātua.
"We are hearing from our young people that it has become easier to get meth than it is to get cannabis, they have said they could even buy it at school.
She said they knew they didn't have all the answers.
"We aren't saying we know everything, just that we really need our hapu, our iwi, our whānau to get involved in this challenge."
