Macfarlane said the participants would delve deeper than practising waiata and haka and the course would focus on values.
"Tika, in tikanga, it means to do the right thing. On the marae it is not okay to be violent, it is not okay to steal, and what you cannot do here, you should not do out there over the fence.
"We are about looking after people and fostering love and kindness, and we are doing this in an atmosphere where people can feel supported, under the guidance of kaumātua. Not just talking about it either, doing it. "
Macfarlane said such a course would have changed the path of his life at an earlier stage.
"There are men and women still struggling in prison in dark places. They need support like this now while they are in there, and opportunity to change and deeply understand their tikanga culture."
He acknowledged there was an obvious divide between the offenders and non-offenders "but the common factor is that we are all people".
"We have a system of funding punishment in prisons, rather than fixing the problems.
"Instead of kicking a kid out of home, you can help them solve the problems behind their behaviour.
"In my eyes, prison is an 'ambulance at the bottom of the cliff' approach and at the top of the cliff we have very little."
Macfarlane was self-funding the course and has received some community money, but not enough to reach the estimated $42,000 to run the course.
To help raise money, Macfarlane has started a Givealittle page and hosted a public talk on Saturday night to tell his story.
"A story of a young man who grew up in Owhata and was imprisoned at a very young age.
"A story of drugs, violence, prison riots, escapes and high-speed police chases... A story of a man from Rotorua who has lived most of his life in the underworld but eventually found solace and guidance inside his culture."
