Te Pāti Māori's extraordinary display of protest - interrupting the first vote on the Treaty Principles Bill - has highlighted the tension between Māori tikanga, or customs, and the rules of Parliament.

This is the moment New Zealand Maori MPs disrupt parliament with a haka to protest against a treaty bill. New Zealand’s parliament was briefly suspended on Thursday (14 November), after Maori members staged a haka to disrupt the vote on a contentious bill that could reinterpret an 184-year-old treaty between the British and Indigenous Maori.
