The political status of the Cook Islands and Niue is formally defined as being states in free association within the Realm of New Zealand, which is made up of the Cook Islands, Niue, and New Zealand and its territories, Tokelau and the Ross Dependency. The Cook Islands and Niue do not have full constitutional independence from New Zealand but act as independent countries. Some countries have recognised them as sovereign entities and established diplomatic relations. However, New Zealand may carry out defence and foreign affairs on behalf of the two associated states when requested.
New Zealand is officially responsible for the defence and foreign affairs of the Cook Islands and Niue. The Act of the New Zealand Parliament which established self-governance mentions a role for New Zealand, but the Constitution of the Cook Islands does not.[1] However, these responsibilities confer New Zealand no rights of control and can only be exercised at the request of the Cook Islands and Niue. The Cook Islands and Niue have been recognised as sovereign states by some countries, and maintain diplomatic relations under their own name. The United States recognises the Cook Islands as a sovereign and independent state,[2] and has signed treaties with the Cook Islands government. Moreover, the Secretary General of the United Nations has determined that the admission of the Cook Islands and Niue into the World Health Assembly means that they have been accepted as states by the international community.[3][4][5][6]
Although the Cook Islands and Niue behave as sovereign states in international law, their constitutional statuses within the Realm of New Zealand (i.e., for matters of New Zealand domestic law) is different from that of a fully independent state, considering that all of Niue's and the Cook Islands' nationals are automatically New Zealand citizens, and both have New Zealand's Monarch as their own head of state. Neither the Cook Islands nor Niue has decided to join the United Nations, as New Zealand has expressed a view that such a move would lead to their loss of the right to automatic acquisition of New Zealand citizenship. However, New Zealand has never formally opposed such application, nor has it argued that either country would not be within its sovereign right to do so.[7] Some scholars have argued that a lack of separate Cook Islands citizenship places an effective limit on the ability of the Cook Islands to act as a sovereign entity, while others have argued that the participation of the Cook Islands in international organisations (such as the Pacific Islands Forum) shows that Cook Islands sovereignty is not limited by the free association arrangement.[8][9]
History
Formerly dependencies of New Zealand, the Cook Islands became a state in free association with New Zealand on 4 August 1965; Niue became a state in free association on 19 October 1974, after a constitutional referendum. In 1992, the UN recognised both states' right to establish diplomatic relations with other countries.[10] Since then, both the Cook Islands and Niue have been allowed to attend UN-sponsored conferences open to "all States" as well as sign and ratify UN treaties open to "non-member states".
New Zealand has formally allowed the Cook Islands to independently conduct its own foreign affairs since 6 April 2001.[11] Niue was granted this power in 2007.[12]
The Repertory of Practice of United Nations Organs records that in 1988 "New Zealand stated that its future participation in international agreements would no longer extend to" Niue and the Cook Islands.[13] The Cook Islands and Niue were granted membership of UNESCO by 1993 and of the World Health Organization by 1994. Also by 1994, the UN Secretariat had "recognized the full treaty-making capacity ... of Niue".[13] As of 2022, the Cook Islands, Kosovo, and Niue are the only state parties that participate in UN specialised agencies, but which are not member states of the UN nor observer states with the United Nations General Assembly. Additionally, the Republic of China on Taiwan participated in the World Health Assembly as Chinese Taipei from 2009 to 2016.
In September 2022, the United States announced its recognition of the Cook Islands and Niue as sovereign states during President Biden's Summit with Pacific Islands Countries (PIC) Leaders in Washington, D.C.[14] In September 2023, recognition was declared and diplomatic relations were established.[15][16] The United States also announced it intends to open an embassy in the Cook Islands and an embassy in Niue in 2024.[17]

States with which the Cook Islands and Niue have diplomatic relations
In 1980, the Cook Islands–United States Maritime Boundary Treaty was signed. The United States recognised the ability of the Cook Islands to negotiate a treaty on its own only after consulting the New Zealand government regarding the exact status of the Cook Islands. In response to the United States' request the New Zealand government confirmed "the competence of the Cook Islands Government to undertake the obligations and exercise the rights under the draft [bilateral] treaty".[111] Consequently, the United States signed a bilateral treaty with the Cook Islands recognizing the latter's sovereignty over the islands subject to the said treaty and its treaty-making power.[111] The Cook Islands and the United States have maintained consular relations since 1995.[112] As of 2011, the State Department included the Cook Islands under the sovereignty of New Zealand in its list of "Dependencies and Areas of Special Sovereignty".[113] As of 2014, The World Factbook listed the Cook Islands as a "self-governing territory in free association with New Zealand".[114] As of 2023, both the State Department and The World Factbook consider the Cook Islands as an independent state.[115][116]
In September 2022, the United States announced its intention to recognise the Cook Islands as a sovereign state during President Biden's Summit with Pacific Islands Countries (PIC) Leaders in Washington, D.C.[117][14]
In September 2023, recognition was declared and diplomatic relations were established.[118][119] The United States also announced it intends to open an embassy in the Cook Islands in 2024.[17]
Niue
In 1997, the United States and Niue signed a maritime boundary treaty that mentioned how "Prior to signing the treaty, the political status of Niue was addressed".[120] As of 2011, the State Department included Niue under the sovereignty of New Zealand in its list of "Dependencies and Areas of Special Sovereignty".[113] As of 2014, The World Factbook listed Niue as a "self-governing territory in free association with New Zealand".[121] As of 2023, both the State Department and The World Factbook consider Niue as an independent state.[115][122]
In September 2022, the United States announced its intention to recognise Niue as a sovereign state during President Biden's Summit with Pacific Islands Countries (PIC) Leaders in Washington, D.C.[123][14]
In September 2023, recognition was declared and diplomatic relations were established.[124][125] The United States also announced it intends to open an embassy in Niue in 2024.[17]
States that recognise the Cook Islands and Niue as self-governing territories
Though the French Ambassador to New Zealand is also accredited to the Cook Islands and Niue, France still describes them as having "no international sovereignty".[126][127]
On 1 July 1994, Israel and New Zealand signed an agreement establishing diplomatic relations. The document stated:[128]
In the cases of the association of New Zealand with the Cook Islands and Niue, the relevant constitution acts provide that, while these territories will be self-governing, 'Her Majesty the Queen in right of New Zealand' will retain responsibility for 'external affairs and defence'.
...
It should also be noted, however, that there exist a number of instances of non-independent entities being permitted to participate in international organizations, though this almost only occurs in cases of associate statehood.
Israel established diplomatic relations with the Cook Islands in April 2008 and with Niue on 3 August 2023.[45][129]
On 11 June 2001, Helen Clark and Terepai Maoate signed an agreement establishing diplomatic relations between the Cook Islands and New Zealand. The document stated:[130]
Any action taken by New Zealand in respect of its constitutional responsibilities for the foreign affairs of the Cook Islands will be taken on the delegated authority, and as an agent or facilitator at the specific request of, the Cook Islands. Section 5 of the Cook Islands Constitution Act 1964 thus records a responsibility to assist the Cook Islands and not a qualification of Cook Islands' statehood.
Clark later said that if the Cook Islands wanted to be its own sovereign state, it would first need its own citizenship.[131] New Zealand believes that if the Cook Islands were to become a sovereign state, an independence referendum and constitutional change would occur. The eligibility of New Zealand citizenship would have to change.[130]
Niue
New Zealand has stated that Niue's free association is "a status distinct from that of full independence".[132]
The Cook Islands and Niue as microstates
While their respective relationships with New Zealand, as well as their small size, make them rather unusual states, it has been argued that their status is far from unique. According to Zbigniew Dumienski, both the Cook Islands and Niue can be seen as microstates, which are defined as: "modern protected states, i.e. sovereign states that have been able to unilaterally depute certain attributes of sovereignty to larger powers in exchange for benign protection of their political and economic viability against their geographic or demographic constraints." Both the Cook Islands and Niue, as well as such states as Andorra, Liechtenstein, Monaco, Nauru, San Marino, and Vatican City, fit into this definition of microstates.[133]

The question of whether the Cook Islands and Niue were 'independent' entities, i.e. – States, with full treaty making capacity was also considered. The Cook Islands and Niue maintained the status of self-governing territories in free association with New Zealand. In view of this special relationship with New Zealand, which discharged the external affairs and defense of the Cook Islands and Niue, neither the Cook Islands nor Niue could invoke the 'all States' clause to participate in treaties deposited with the Secretary-General unless specifically invited to participate in a treaty.
