Claims and settlements under the Treaty of Waitangi (Māori: Te Tiriti o Waitangi) have been a significant feature of New Zealand politics since the Treaty of Waitangi Act 1975 and the Waitangi Tribunal that was established by that act to hear claims. Successive governments have increasingly provided formal legal and political opportunity for Māori to seek redress for what are seen as breaches by the Crown of guarantees set out in the Treaty of Waitangi. While it has resulted in putting to rest a number of significant longstanding grievances, the process has been subject to criticisms including those who believe that the redress is insufficient to compensate for Māori losses. The settlements are typically seen as part of a broader Māori Renaissance.

The Waitangi Tribunal was set up as the primary means of registering and researching claims because the Treaty of Waitangi itself has little legal standing. The primary means of settling those claims is through direct negotiations with the government of the day.
