The party already has a policy to “divorce” New Zealand from the British royal family and create a “Te Tiriti-centric Aotearoa” through constitutional transformation, based on the country’s founding document Te Tiriti o Waitangi.
The statement says indigenous people in the countries involved are recovering from “centuries of racism, oppression, colonialism and slavery, now rightly recognised by the United Nations as ‘Crimes Against Humanity’.”
They also call for a formal apology and for a process of reparatory justice to commence.
The signatories refer to comments from then-Prince Charles at the Commonwealth Heads of Government Meeting in Rwanda in June last year, where he said that the wrongs of the past were a “conversation whose time has come” and expressed personal sorrow over “slavery’s enduring impact”.
They call for a commitment to discussions about reparations for “the oppression of our peoples, plundering of our resources, denigration of our culture and to redistribute the wealth that underpins the Crown, back to the peoples from whom it was stolen”.
They also ask the King to “immediately commit” to the repatriation of all remains of peoples that reside in UK museums and institutions, along with artefacts stolen through “hundreds of years of genocide, enslavement, discrimination, massacre, and racial discrimination by the authorities empowered by the protection of the British Crown”.
The statement is also signed by the chair of the advocacy group New Zealand Republic - Kia Mana Motuhake a Aotearoa, Lewis Holden, and a similar advocacy group in Australia.
Australian Independent Senator for Victoria Lidia Thorpe has also signed the statement, representing the black sovereignty movement there.
Te Pāti Māori has not responded to requests for comment.
The party has been largely keeping out of the media since former Labour MP and minister Meka Whaitiri yesterday announced she was defecting to Te Pāti Māori.

Hipkins, a republican, said ahead of his departure he did not think it was a priority for New Zealand to break away from the monarchy anytime soon.
A recent poll found the majority of Kiwis think New Zealand will be ready to become a republic in 10 years.
