How is the colonisation of Australia and New Zealand distinct from the rest of new imperialism

The British colonized Australia by first creating prison colonies for convicts from Great Britain. New Zealand has two main islands and is home to the Maori, who were originally from Polynesia. The British colonized New Zealand and often were in conflict with the Maori. One similarity is that both countries were colonies of Great Britain at one time. Both countries are island nations in the South Pacific. There is also a free movement of people between the two countries. There are many Australians that live in New Zealand and vice versa.
