Over 10,000 people in New Zealand are taking part in a march toward the capital Wellington to protest legislation that would reinterpret an 1840 treaty — considered New Zealand’s founding document — and rolling back long-standing rights for Indigenous Māori communities. On Thursday, 22-year-old Maori lawmaker Hana-Rawhiti Maipi-Clarke tore up a copy of the proposed bill and was joined by other lawmakers in performing a Māori haka on the Parliament floor, suspending the session.

This comes just days after New Zealand’s Prime Minister Christopher Luxon offered an apology to the survivors and families of hundreds of thousands of children and vulnerable adults who were physically, sexually and psychologically abused in state institutions over the last 70 years — a large proportion of whom were from the Māori community.
