In 1980, the maritime boundary between American Samoa and Tokelau was established, traversing east to west and spanning 318 nautical miles in the central South Pacific Ocean. American Samoa, a territory of the United States, and Tokelau, a non-self-governing island of New Zealand, agreed on the boundary as a delimitation line for all purposes. The boundary is composed of a starting point, terminal point and six interior turning points. The principle of equidistance was used in constructing the line, utilizing American Samoa’s Swains Island as a control point for the United States, and Tokelau’s atolls of Fakaofo and Nukunonu as controlling points for New Zealand.
