UNDRIP (United Nations Declaration on the Rights of Indigenous Peoples) is an international human rights document on the rights of indigenous peoples. The Declaration was adopted by the United Nations General Assembly on 13 September 2007. It provides a set of international human rights standards that apply to the Treaty of Waitangi. The Treaty affirmed the rights Tangata Whenua had prior to 1840 and gave Tauiwi and the Crown a set of rights and responsibilities that enabled them to settle in Aotearoa; “the promise of two peoples to take the best possible care of each other.”
