Watch: Pōwhiri for parliamentarians at Waitangi

Politicians have been welcomed onto Te Whare Runanga on the treaty grounds at Waitangi today, with leaders of political parties making statements.

Watch a stream of the pōwhiri here:

Hirini Tau, opening for hau kāinga, welcomed the MPs to Te Whare Rūnanga, to recognise the signing of "our child" called Te Tiriti o Waitangi at the sacred place of Ngāpuhi.

He spoke of how the treaty affirmed He Whakaputanga, and about how the shared waka between tangata whenua and the Crown had been unbalanced since 1840.

He paid tribute to late Northland kuia Titiewhai Harawira and the late Queen Elizabeth II.

"We are one people from that time till this time."

Kipa Munro was the second speaker, addressing PM and all MPs he said: "You are of one mind and that is for the benefit of the people."

He said that was the case for MPs "no matter how high or low your position".

The third speaker Shane Jones directly addressed David Seymour, explaining his Ngāti Rehia whakapapa line, and then said: "I've just given you your genealogy I suggest that you live up to it."

Jones said to all MPs: "I shall see you at the end of the year."

Te Pāti Māori leader Rawiri Waititi

Rawiri Waititi told Ngāpuhi to stay strong "in their struggle against this house", and spoke on climate change after recent devastating flooding throughout the motu.

"We cannot change the climate; we are not gods, but we must change our behaviours and our actions."

Labour Party leader Prime Minister Chris Hipkins

Prime Minister Hipkins also acknowledged the passing of Titewhai Harawira, and how each year at Waitangi Labour came "knowing full well that if we've not met her expectations that she was going to tell us and so we miss her here this year".

As the former Minister of Education, Hipkins said he was "particularly proud to reflect on one of my most proud achievements in that role, ensuring that Aotearoa New Zealand history will be taught in all of our schools to all of our young people".

"This is a day of coming together and yes, it'll be a day of difference and sometimes some of that difference becomes a little more visual than other other times."

He said that on the treaty process, "Much of the contemporary debates, unfortunately, is still characterised by a degree of uncertainty and fear."

"With honesty and with understanding we can overcome this and we can see this process through."

Hipkins also spoke on the inequalities in the health system and criminal justice system for Māori.

"The future prosperity of Māori will result in the future prosperity of all of us."

"We acknowledge that we won't always get that right. And that sometimes we'll need to continue to discuss in debate, and sometimes things will need to change."

ACT Party leader David Seymour

David Seymour spoke in te reo to the assembly, saying "We must cherish Māori language and culture."

"Our party believes if we look forward all people must live equally. We believe in self determination for all people under the powers of the governments."

He said that "perhaps" those who signed the Treaty would support Act.

"We believe in self-determination for all under the powers of the government."

National Party leader Christopher Luxon

Christopher Luxon also began his talk in te reo acknowledging mana whenua and said: "It is a great privilege to be here ... The birthplace of our nation."

The treaty settlement process was something New Zealanders can be proud of, he said.

"Most New Zealanders can see that settlements have been a genuine best endeavour to put things right."

The process "settles claims forever" and "brings an end to grievance", he said.

National would work "faithfully" with Ngāpuhi for iwi to settle claims, Luxon said.

"We started on the 6th of February 1840 as a little experiment, and look at us now - the 21st century success story able to tackle the challenges that come our way."

Green Party MP Teanau Tuiono also spoke in te reo Māori.

After a flurry of confusion, it was agreed leaders would speak during the pōwhiri.
