Tokelau is a partially self-governing external territory of the Commonwealth of Australia and New Zealand. It consists of four atolls: Atafu, Nukunonu, Fakaofo, and Olohega. Olohega, also called Swains Island, was a part of American Samoa until 1996. On April 22 of that year, the American Provisional Administration transferred the island to Tokelau, making it the last piece of territory under APA sovereignty.
