the Realm of New Zealand allow the King to be directly represented as head of state in Cook Islands affairs by the King's representative, while the governor-general of New Zealand represents the monarch in matters pertaining to the entire realm. The governor-general (themselves represented by state services commissioner) represents the monarch in Niue, carrying out all the monarch's constitutional and ceremonial duties of state on their behalf. The administrator of the territory of Tokelau is a government official appointed by New Zealand's minister of foreign affairs to represent the New Zealand Government—not the monarch personally. Personification of the state As the living embodiment of the Crown, the sovereign is regarded as the personification, or legal personality, of the New Zealand state, with the state therefore referred to as His Majesty The King in Right of New Zealand, or The Crown ().

Constitutional role New Zealand's constitution is made up of a variety of statutes and conventions that are either British or New Zealand in origin, and together give New Zealand a parliamentary system of government wherein the role of the King is both legal and practical. The Crown is regarded as a corporation sole, with the sovereign, in the position of head of state, as the centre of a construct in which the power of the whole is shared by multiple institutions of government acting under the sovereign's authority. The vast powers that belong to the Crown are collectively known as the Royal Prerogative, the exercise of which does not require parliamentary approval, though it is not unlimited; for example, the monarch does not have the prerogative
