What year did New Zealand become a British colony?

New Zealand became a British colony in 1840 when the Treaty of Waitangi was signed. This treaty, signed between many Māori chiefs and representatives of the British Crown, was intended to establish a legal framework for British settlement and govern relations between the British and Māori. It is regarded as a foundational document in New Zealand's history, marking the beginning of New Zealand's transition from a group of islands inhabited by Māori communities to a British colony. Understanding the significance of this event is crucial, as it laid the groundwork for the development of modern New Zealand society, law, and governance. The significance of the year 1840 is further underscored by ongoing discussions around the Treaty of Waitangi and its implications in contemporary New Zealand.
