Te Ture Whenua Māori Act 1993, ss 114A–116; Māori Land Court Rules 2011, Schedule, Form 21
Yes. The Māori Land Court can consider whāngai when determining the deceased’s successors (a whāngai is a person adopted in accordance with tikanga Māori.) The court will follow iwi and hapū tikanga in deciding whether a whāngai can be included in succession.
If the court decides that tikanga does not allow a whāngai to be included in succession, but that this leads to an injustice, it can still order that they be allowed to live in the family home (if it is on the land in question), and/or receive income from the land, either for their lifetime, or for a specific period of time.
