The Realm of New Zealand consists of the entire area (or realm) in which the monarch of New Zealand functions as head of state. The Realm of New Zealand is not a federation; it is a collection of states and territories united under its monarch. New Zealand is an independent and sovereign state. It has one Antarctic territorial claim (the Ross Dependency), one dependent territory (Tokelau), and two associated states (the Cook Islands and Niue).
The Ross Dependency has no permanent inhabitants, while Tokelau, the Cook Islands and Niue have indigenous populations. The United Nations formally classifies Tokelau as a non-self-governing territory; the Cook Islands and Niue are internally self-governing, with New Zealand retaining responsibility for defence and for most foreign affairs. The governor-general of New Zealand represents the monarch throughout the Realm of New Zealand, though the Cook Islands have an additional Queen's Representative.
The monarch of New Zealand, represented by the governor-general of New Zealand, is the head of state throughout the Realm of New Zealand. The New Zealand monarchy is unitary throughout all jurisdictions in the realm, with the headship of state being a part of all equally. The 1983 Letters Patent Constituting the Office of Governor-General of New Zealand define the exact scope of the realm.
The Pacific islands of the Cook Islands and Niue became New Zealand's first colonies in 1901 and then protectorates. From 1965 the Cook Islands became self-governing, as did Niue from 1974. Tokelau came under New Zealand control in 1925 and remains a non-self-governing territory.
The Ross Dependency comprises that sector of the Antarctic continent between 160° east and 150° west longitude, together with the islands lying between those degrees of longitude and south of latitude 60° south. The British (imperial) government took possession of this territory in 1923 and entrusted it to the administration of New Zealand. Neither Russia nor the United States recognises this claim, and the matter remains unresolved (along with all other Antarctic claims) by the Antarctic Treaty, which serves to mostly smooth over these differences. The area is uninhabited, apart from scientific bases.
New Zealand citizenship law treats all parts of the Realm equally, so most people born in New Zealand, the Cook Islands, Niue, Tokelau and the Ross Dependency before 2006 are New Zealand citizens. Further conditions apply for those born from 2006 onwards.

A governor-general represents the head of state—Elizabeth II, in her capacity as Queen of New Zealand—in the area of the realm. Essentially, governors-general take on all the dignities and reserve powers of the head of state. Dame Patsy Reddy was appointed to assume the position on 14 September 2016.
Both the Cook Islands and Niue are self-governing states in free association with New Zealand. The details of their free association arrangement are contained in several documents, such as their respective constitutions, the 1983 Exchange of Letters between the governments of New Zealand and the Cook Islands, and the 2001 Joint Centenary Declaration. As such, the New Zealand Parliament is not empowered to unilaterally pass legislation in respect of these states. In foreign affairs and defence issues New Zealand acts on behalf of these countries, but only with their advice and consent.
As the governor-general is resident in New Zealand, the Cook Islands Constitution provides for the distinct position of Queen's representative. This individual is not subordinate to the governor-general and acts as the local representative of the Queen in right of New Zealand. Since 2013, Tom Marsters is the Queen's representative to the Cook Islands. (Marsters was preceded by Sir Frederick Tutu Goodwin.) This arrangement effectively allows for the de facto independent actions of internal and most external areas of governance.
In the Cook Islands and Niue, the New Zealand high commissioner is the diplomatic representative from New Zealand. John Carter (since 2011) is the New Zealand High Commissioner to the Cook Islands, and Ross Ardern (since 2014) is the New Zealand High Commissioner to Niue.
Despite their close relationship to New Zealand, both the Cook Islands and Niue maintain some diplomatic relations in their own name. Both countries maintain High Commissions in New Zealand and have New Zealand High Commissioners resident in their capitals. In Commonwealth practice, High Commissioners represent their governments, not the Head of State.
Tokelau has a lesser degree of self-government than the Cook Islands and Niue, and had been moving toward free association status. New Zealand's representative in Tokelau is the Administrator of Tokelau and has the power to overturn rules passed by the General Fono (parliament). In referenda conducted in 2006 and 2007 by New Zealand at the United Nations' request, the people of Tokelau failed to reach the two-thirds majority necessary to attain a system of governance with equal powers to that of Niue and the Cook Islands.
Within New Zealand, there exists some support for a New Zealand republic. Should New Zealand become a republic, it would retain the Ross Dependency and Tokelau as dependent territories and the Realm of New Zealand would continue to exist without New Zealand, the Ross Dependency and Tokelau. This would not be a legal hurdle to a New Zealand republic as such, and both the Cook Islands and Niue would retain their free association with New Zealand. Rights to abode and citizenship, codified in New Zealand legislation by the Citizenship Act 1977, would not change.
However, a New Zealand republic would present the issue of continued allegiance to the Sovereign to the Cook Islands and Niue. Thus, a number of options for the future of the Realm of New Zealand exist should New Zealand become a republic with the Cook Islands and Niue either:
|Countries||New Zealand||Cook Islands||Niue|
|Regions||11 non-unitary regions||5 unitary regions||Chatham Islands||Kermadec Islands
NZ Subantarctic Islands
Three Kings Islands
|Tokelau||Ross Dependency||15 islands||14 villages|
|Territorial authorities||11 cities and 50 districts||2 cities and 3 districts|
|Notes||Some districts lie in more than one region||These combine the regional and the territorial authority levels in one||Special territorial authority||New Zealand outlying islands outside any regional authority (the outlying Solander Islands form a part of the Southland Region)||Non-self-governing territory of New Zealand||New Zealand's Antarctic dependency||States in free association with New Zealand|
