The Department of Island Territories was a New Zealand government department that was tasked with administrating New Zealand's three Pacific Islands territories—the Cook Islands, Niue, and Tokelau—and the country's League of Nations mandate, Samoa. It was established on 3 October 1919 under the "External Affairs Bill" as the Department of External Affairs. In 1943, the Department was renamed the Department of Island Territories after a separate Department of External Affairs was created to conduct the country's external relations. In 1975, the Department was dissolved and its functions were absorbed back into the Ministry of Foreign Affairs, the successor to the External Affairs Department.
