New Zealand’s Parliament was temporarily suspended on Thursday as Māori lawmakers performed a haka, a traditional group dance, demonstrating their community’s anger and fear over a bill that aims to reinterpret the country’s founding treaty with its Indigenous people.

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.

Following Maipi-Clarke ringing haka – a rhythmic Maori chant of challenge, it led to a roar from the opposition lawmakers and the spectators and ultimately her suspension from the parliament for the day.
