The Treaty Principles Bill seeks to revise New Zealand’s foundational agreement with Maori people and is hugely unpopular, with even the prime minister deriding it.

The Treaty of Waitangi, which is the focus of the proposed bill, dates back to 1840 and is considered New Zealand's founding document. The agreement was signed by Māori chiefs and the British monarchy and focused on rectifying wrongs done to the indigenous people when the country was colonized.
