1840 British occupation of New Zealand marked the formation of British colonial system in the world.

1840 is the last colonization. The earliest British colonization was in 1607. 1840 occupied New Zealand, ending his colonial career. After that, British colonies spread all over India, Canada, Africa, Australia and New Zealand, and their colonies surrounded the world. It also marks the formation of British colonial system in the world. This is the title of The Sun Never Sets. That's awesome.

Also, New Zealand is not so much a colony as an immigrant. After the sparsely populated Maori were conquered by the British, Britain sent a large number of its own immigrants to New Zealand. Completely regard New Zealand as its own territory. Turn New Zealand into a "second Britain". This is similar to what the United States did to Indians in those days. Although India is controlled by Britain, its population composition is still Indian, and ancient Indian culture still dominates. This is similar to the semi-social nature of China in the late Qing Dynasty, so strictly speaking, New Zealand's colonization is more fundamental.
