WELLINGTON, New Zealand (AP) — As tens of thousands of marchers crowded the streets in New Zealand’s capital Wellington on Tuesday, the throng of people, flags aloft, had the air of a festival or a parade rather than a protest. They arrived to oppose a law that would reshape the county’s founding treaty between Indigenous Māori and the British Crown. But for many, it was about something more: a celebration of a resurging Indigenous language and identity that colonization had once almost destroyed.
