Offenders will be expected to take part in a powhiri and whakawhanaungatanga, a process for establishing relationships.
Whangarei District Court Judge Greg Davis and Hamilton-based Judge Denise Clark, who is from Kohukohu, have led the development of the Rangatahi Court in Whangarei.
Judge Clark will be the presiding judge in the new court in the initial months before Judge Greg Davis takes over later this year.
By July next year the Youth Court jurisdiction will be extended to include most 17-year-old offenders.
Five Rangatahi courts are operating in Auckland, and one each in Gisborne, New Plymouth, Hamilton, Whakatane, Rotorua, Huntly, Tauranga, Taupo and Christchurch.
Rangatahi Court is based on the Koori Court model in Perth and Victoria in Australia where the court processes are adjusted to cater for Aboriginal youth offenders.
Almost two out of three young people who appear in the Youth Court are Maori.
