This time the vote was short by just 16 votes or 3%. In May 2008, the United Nations' Secretary General Ban Ki-moon urged colonial powers "to complete the decolonization process in every one of the remaining 16 non-self-governing territories", including Tokelau. This led The New Zealand Herald to comment that the United Nations was "apparently frustrated by two failed attempts to get Tokelau to vote for independence". In April 2008, speaking as leader of the National Party, future New Zealand Prime Minister John Key stated that New Zealand had "imposed two referenda on the people of the Tokelau Islands", and questioned "the accepted wisdom that small states should undergo a de-colonisation process". Geography Tokelau includes three atolls in the South Pacific Ocean between longitudes 171° W and 173° W and between latitudes 8° S and 10° S, about midway between Hawaii and New Zealand. From Atafu in the north to Fakaofo in the south, Tokelau extends for less than 200 km. The atolls lie about north of Samoa. The atolls are Atafu and Nukunonu, both in an island group once called the Duke of Clarence Group, and Fakaofo, once Bowditch Island. Their combined land area is . The atolls each have a number of coral islands, where the villages are situated. The highest point of Tokelau is just above sea level. There are no ports or harbours for large vessels, however, all three atolls have a jetty to and from which supplies and passengers are shipped. Tokelau lies in the Pacific tropical cyclone belt. A fourth island that is culturally, historically, and geographically, but not politically, a part of the Tokelau Islands is Swains Island (Olohega), under United States control since about 1900 and administered as a part of American Samoa since 1925. Swains Island was claimed by the United States pursuant to the Guano Islands Act, as were the other three islands of Tokelau; the latter three claims were ceded to Tokelau by treaty in 1979. In the draft constitution of Tokelau subject to the Tokelauan self-determination referendum in 2006, Olohega (Swains Island) was also claimed as a part of Tokelau, though the claim was surrendered in the same 1979 treaty. This established a clearly defined boundary between American Samoa and Tokelau. Tokelau's claim to Swains is generally comparable to the Marshall Islands' claim to U.S.-administered Wake Island, but the re-emergence of this somewhat dormant issue has been an
