Three New Zealand Te Pāti Māori MPs—Debbie Ngarewa-Packer, Rawiri Waititi, and Hana-Rāwhiti Maipi-Clarke—refused to appear before the Privileges Committee, citing breaches of natural justice and discrimination. Their protest involved performing a haka during the discussion of the Treaty Principles Bill. The MPs criticized the parliamentary system for marginalizing Māori cultural expressions and voices.
