The Cook Islands and Niue, which are both associated states of New Zealand, are not members of the UN, but are members of specialized agencies of the UN such as WHO and UNESCO, and have had their "full treaty-making capacity" recognized by United Nations Secretariat in 1992 and 1994 respectively. They have since become parties to a number of international treaties which the UN Secretariat acts as a depositary for, such as the United Nations Framework Convention on Climate Change and the United Nations Convention on the Law of the Sea, and are treated as non-member states. Both the Cook Islands and Niue have expressed a desire to become a UN member state, but New Zealand has said that they would not support the application without a change in their constitutional relationship, in particular their right to New Zealand citizenship.
