Realm of New Zealand in the context of "New Zealand nationality law"

An economic and monetary union (EMU) is a type of trade bloc that features a combination of a common market, customs union, and monetary union. Established via a trade pact, an EMU constitutes the sixth of seven stages in the process of economic integration. An EMU agreement usually combines a customs union with a common market. A typical EMU establishes free trade and a common external tariff throughout its jurisdiction. It is also designed to protect freedom in the movement of goods, services, and people. This arrangement is distinct from a monetary union (e.g., the Latin Monetary Union), which does not usually involve a common market. As with the economic and monetary union established among the 27 member states of the European Union (EU), an EMU may affect different parts of its jurisdiction in different ways. Some areas are subject to separate customs regulations from other areas subject to the EMU. These various arrangements may be established in a formal agreement, or they may exist on a de facto basis. For example, not all EU member states use the Euro established by its currency union, and not all EU member states are part of the Schengen Area. Some EU members participate in both unions, and some in neither.

Territories of the United States, Australian External Territories and New Zealand territories each share a currency and, for the most part, the market of their respective mainland states. However, they are generally not part of the same customs territories.

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. Despite both states acting internationally as independent countries, all Cook Islands and Niue nationals are automatically New Zealand citizens, and while both the Cook Islands and Niue have expressed a desire to become full members of the United Nations, 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.

A total of 65 UN member states have recognised the Cook Islands as a sovereign country and established diplomatic relations, whereas 28 UN member states have done so with Niue. However, New Zealand may still carry out defence and foreign affairs on behalf of the two associated states when requested.

A Commonwealth realm is a sovereign state in the Commonwealth of Nations that has the same constitutional monarch and head of state as the other realms. The current monarch is King Charles III. Except for the United Kingdom, in each of the realms the monarch is represented by a governor-general. The phrase Commonwealth realm is an informal description not used in any law.

As of 2025, there are 15 Commonwealth realms: Antigua and Barbuda, Australia, The Bahamas, Belize, Canada, Grenada, Jamaica, New Zealand, Papua New Guinea, Saint Kitts and Nevis, Saint Lucia, Saint Vincent and the Grenadines, Solomon Islands, Tuvalu, and the United Kingdom. While the Commonwealth of Nations has 56 independent member states, only these 15 have Charles III as head of state. He is also Head of the Commonwealth, a non-constitutional role.

Niue maintains diplomatic relations with various other countries and multilateral organizations. Since 1974, Niue has been a self-governing state in free association with New Zealand. The King in right of New Zealand is the head of state of Niue, making Niue part of the Realm of New Zealand.

This is a list of New Zealand species extinct in the Holocene that covers extinctions from the Holocene epoch, a geologic epoch that began about 11,650 years Before Present (about 9700 BCE) and continues to the present day. This epoch equates with the latter third of the Haweran Stage of the Wanganui epoch in the New Zealand geologic time scale.

The North Island and South Island are the two largest islands of New Zealand. Stewart Island is the largest of the smaller islands. New Zealand proper also includes outlying islands such as the Chatham Islands, Kermadec Islands, and New Zealand Subantarctic Islands. Only New Zealand proper is represented on this list, not the Realm of New Zealand. For extinctions in the Cook Islands, Niue, or Tokelau, see the List of Oceanian animals extinct in the Holocene.

The monarchy of New Zealand is the constitutional system of government in which a hereditary monarch is the sovereign and head of state of New Zealand. The current monarch is King Charles III, who has reigned since 8 September 2022.

The Treaty of Waitangi between Queen Victoria and Māori chiefs (rangatira) was signed on 6 February 1840. This laid the foundation for the proclamation of British sovereignty over New Zealand on 21 May 1840; the British monarch became New Zealand's head of state. The country gradually became independent from Britain and the monarchy evolved to become a distinctly New Zealand institution, represented by unique symbols. The individual who is the New Zealand monarch is currently shared with 14 other countries (realms) within the Commonwealth of Nations, in each of which the monarchy is legally separate. As a result, the current monarch is officially titled King of New Zealand (Māori: Kīngi o Aotearoa) and, in this capacity, he and other members of the royal family undertake various public and private functions across the Realm of New Zealand. The King is the only member of the royal family with any constitutional role.

The king's representative is the official representative of Charles III, as King of the realm of New Zealand, in the Cook Islands. The office of King's Representative is established by the Constitution of the Cook Islands. They are appointed by the King for a term of three years, and may be reappointed. When the Cook Islands has a queen regnant, the viceroy is titled queen's representative.

The king's representative fills the role normally filled by a governor-general in the Westminster system of a Commonwealth realm, being both a representative of the monarch and the titular head of executive government. They appoint the prime minister and Cabinet and chair the Cook Islands Executive Council. In performing their duties, they must act on advice.
