WELLINGTON, New Zealand – Tens of thousands of Māori people took to the streets of Wellington on Tuesday to protest a proposed law that would reinterpret the Treaty of Waitangi, the founding document of New Zealand.

The protesters, many dressed in traditional Māori clothing and waving the Māori flag, marched from the northern part of the North Island to the capital, where they gathered outside Parliament. The demonstration, which was one of the largest in New Zealand's history, was a response to a bill introduced by the ACT Party, a member of the ruling coalition, that seeks to reinterpret the Treaty of Waitangi.

The Treaty of Waitangi, signed in 1840 between the British Crown and Māori chiefs, established British sovereignty over New Zealand. The treaty guaranteed Māori people certain rights, including the ownership of their lands and the protection of their culture and traditions.

The proposed law has sparked outrage among Māori, who fear that it will erode their rights and undermine the principles of the Treaty of Waitangi. Critics argue that the bill is an attempt to rewrite history and to undermine the special status of Māori in New Zealand.

"The bill is trying to take away our rights," said Stan Ringma, a protester of Māori and Swedish descent. "This march is for all New Zealanders."

The protest comes amid growing tensions between Māori and the government. The ruling coalition, led by Prime Minister Chris Hipkins, has faced criticism for its policies towards Māori, including a ban on the use of the Māori language in some government services.

While the proposed law is unlikely to pass, the controversy has highlighted deep divisions within New Zealand society over the country's history and the rights of its indigenous people. Critics of the bill argue that it is an attempt to divide New Zealanders and to pit Māori against other New Zealanders.

"This is about more than just the Treaty of Waitangi," said Kawin Jones, a New Zealand law professor who specializes in indigenous rights. "This is about the future of our country and whether we will be a nation that respects the rights of all its people."

The protests have also raised concerns about the rise of right-wing populism in New Zealand. Some observers have warned that the proposed law could embolden anti-Māori sentiment and lead to a further erosion of Māori rights.
