The New Zealand Parliament is the unicameral legislature of New Zealand, consisting of the Sovereign (King-in-Parliament) and the New Zealand House of Representatives. The King is usually represented by his governor-general. Before 1951, there was an upper chamber, the New Zealand Legislative Council. The New Zealand Parliament was established in 1854 and is one of the oldest continuously functioning legislatures in the world. It has met in Wellington, the capital of New Zealand, since 1865 and in its current building since 1922.
