A vote in New Zealand’s parliament was suspended and two lawmakers were ejected on Thursday when a ringing haka began – a rhythmic Māori chant of challenge – over a controversial bill redefining the country’s founding agreement between Indigenous Māori and the British Crown.

Rawhiti Maipi-Clarke of Te Pāti Māori stood and began a rhythmic Māori chant of challenge, which swelled to a roar as opposition lawmakers and spectators in the public gallery joined in.
