Wellington is the capital city of New Zealand.

Wellington is located at the southwestern tip of the North Island, between Cook Strait and the Remutaka Range. Wellington is the second-largest city in New Zealand by metro area and is the administrative center of the Wellington Region. It is the world's southernmost capital of a sovereign state. Wellington features a temperate maritime climate and is the world's windiest city by average wind speed.

Wellington was originally designed by Captain William Mein Smith, the first Surveyor-General for Edward Wakefield's New Zealand Company, in 1840. As of June 2021, the Wellington urban area (which only includes urbanized areas within Wellington City) has a resident population of 215,900. Its metro area, which includes the cities of Porirua, Upper Hutt, and Lower Hutt, has a resident population of 432,800. The city has served as New Zealand's capital since 1865, a status that is not defined in legislation, but established by convention; the New Zealand Government and Parliament, the Supreme Court, and most of the public services are based in the city.
