New Zealand's parliament was suspended and two lawmakers were ejected during a vote on a controversial proposed law redefining the country’s founding agreement between Indigenous Māori and the British Crown.

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.

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.
