Tens of thousands of New Zealanders rallied in front of parliament on Tuesday in one of the country's largest ever protests to oppose a bill, which opponents say seeks to dilute the rights of Maori and threatens to set race relations back decades.

In a historic protest, over 42,000 New Zealanders gathered at the parliament to oppose the Treaty Principles Bill, which aims to reinterpret the Treaty of Waitangi. Critics argue the bill threatens Maori rights and race relations.
