The principles of the Treaty of Waitangi (Māori: ngā mātāpono o te tiriti) is a set of principles derived from, and interpreting, the Treaty of Waitangi, which was signed in New Zealand in 1840. The phrase "principles of the Treaty of Waitangi" was first used in the Treaty of Waitangi Act 1975, and the principles were codified in 1987. There is no final list and they are determined on a case-by-case basis. They include the three Ps: partnership, participation and protection of rangatiratanga (Māori authority).[1]
