Claims and settlements under the Treaty of 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 Māori renaissance, as a turning point in New Zealand's history, describes a loosely defined period between 1970 and the early 2000s, in which Māori took the lead in turning around the decline of their culture and language that had been ongoing since the early days of European settlement. In doing so, social attitudes towards Māori among other New Zealanders also changed.
