New Zealand is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island and the South Island —and over 700 smaller islands. It is the sixth-largest island country by area and lies east of Australia across the Tasman Sea and south of the islands of New Caledonia, Fiji, and Tonga. The country's varied topography and sharp mountain peaks, including the Southern Alps, owe much to tectonic uplift and volcanic eruptions. New Zealand's capital city is Wellington, and its most populous city is Auckland.

Wellington has been the capital of New Zealand since 1865. New Zealand's first capital city was Old Russell (Okiato) in 1840–41. Auckland was the second capital from 1841 until 1865, when Parliament was permanently moved to Wellington after an argument that persisted for a decade. As the members of parliament could not agree on the location of a more central capital, Wellington was decided on by three Australian commissioners.
