Why are the customs and habits in New Zealand similar to those in Europe?

New Zealand was originally a British colony and later became a British dominion. Now it is a member of the Commonwealth and its official language is English.

Look at the flag of New Zealand. In the upper left corner is the British flag, and on the right is the Southern Cross (a representative constellation in the southern hemisphere, just like the Big Dipper in the northern hemisphere).

Therefore, New Zealand and Europe are very similar in historical origin, race, culture, language and customs.
