The famous politics in New Zealand -
Queen Elizabeth II

The monarchy of New Zealand – also referred to as The Crown in Right of New Zealand, Her Majesty in Right of New Zealand, or The Queen in Right of New Zealand – is the constitutional system of government in which a hereditary monarch is the sovereign and head of state of the Realm of New Zealand, forming the core of the country's Westminster-style parliamentary democracy. The Crown is thus the foundation of the executive, legislative, and judicial branches of the New Zealand government.

Elizabeth II (Elizabeth Alexandra Mary; born 21 April 1926) is the Queen regnant of sixteen independent sovereign states known informally as the Commonwealth realms: the United Kingdom, Canada, Australia, New Zealand, Jamaica, Barbados, the Bahamas, Grenada, Papua New Guinea, the Solomon Islands, Tuvalu, Saint Lucia, Saint Vincent and the Grenadines, Belize, Antigua and Barbuda, and Saint Kitts and Nevis. She holds each crown separately and equally in a shared monarchy, as well as acting as Head of the Commonwealth, and Supreme Governor of the Church of England. As a constitutional monarch, she is politically neutral and by convention her role is largely ceremonial.
