Western Samoa achieves independence from New Zealand; its name is changed to the Independent State of Western Samoa.

The Territory of Western Samoa was the civil administration of Western Samoa by New Zealand between 1920 and Samoan independence in 1962. In 1914, German Samoa was captured by the Samoa Expeditionary Force shortly after the outbreak of World War I, and was formally annexed as a League of Nations mandate in 1920 in the Treaty of Versailles. It was later transformed into a United Nations Trust Territory following the dissolution of the League of Nations in 1946.

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 600 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.
