I've got infonesia regarding where I found this, but this is a fascinating article about the way Maori deal with young offenders:
This is restorative justice, a system that has transformed the way juvenile offenders are treated in New Zealand and now embraced wholeheartedly by the British Government. It brings criminals and their victims face to face, and assigns responsibility for retribution to families and the community.
I saw Whalerider on the weekend, which was a somewhat flawed but entertaining tale of a Maori tribe's struggle for meaning in the modern world. It kind of traded on its ethnicity, was overly serious, and clumsily directed, but was still a pretty fascinating and rare look at the New Zealand indigenous peoples.
