Treaty of Waitangi claims and settlements have been a significant feature of New Zealand race relations and politics since 1975. Over the last 30 years, New Zealand governments have increasingly provided formal legal and political opportunity for Māori to seek redress for breaches by the Crown of the 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 from a number of angles, from those who believe that the redress is insufficient to compensate for Māori losses, to those who see no value in revisiting painful and contentious historical issues. The settlements are typically seen as part of a broader Māori Renaissance.
Because the Treaty of Waitangi has limited legal standing in itself, the primary means of registering and researching Treaty claims is through the Waitangi Tribunal. The primary means of settling those claims is through negotiations with the government of the day.
The Treaty of Waitangi is often considered to be the founding document for European (Pākehā) settlement in New Zealand. It guaranteed to Māori the right to keep their lands, forests, fisheries and all their treasures, but they would hand sovereignty in the English version, and governorship in the Māori version, over to the Crown and would also be able to sell only to the Crown. Initially, there was little dispute, as the settlers were able to buy land from the Māori through legal channels. However, after a while, Māori became disillusioned and less willing to sell, while the Crown came under increasing pressure from settlers wishing to buy. Consequently, government land agents were involved in a number of dubious land purchases. Agreements were negotiated with only one owner of tribally owned land and in some cases land was purchased from the wrong people altogether. Unrest and rebellion caused by these actions were met with further punitive land confiscations. Eventually this led to the New Zealand Wars, which culminated in the confiscation of a large part of the Waikato and Taranaki.
