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.

New Zealand’s parliament was briefly suspended on Thursday after Maori members staged a haka to disrupt the vote on a contentious bill that would reinterpret a 184-year-old treaty between the British and Indigenous Maori.

New Zealand ACT Leader David Seymour says the protest haka in parliament shows a “total lack of understanding” over how democracy functions.
