The New Zealand Legislative Council was the upper house of the General Assembly of New Zealand from 1853 to 1950. An earlier legislative council existed from 1841 when New Zealand became a colony; it was reconstituted as the upper house of a bicameral legislature when New Zealand became self-governing in 1852, which came into effect in the following year.
Unlike the elected lower house, the House of Representatives, the Legislative Council was wholly appointed by the governor-general. The New Zealand Constitution Act 1852 had authorised the appointment of a minimum of ten councillors. Beginning in the 1890s, the membership of the upper house became controlled by government of the day. As a result, the Legislative Council possessed little influence. While intended as a revising chamber, in practice, debates and votes typically simply replicated those in the lower house. It was abolished by an Act of Parliament in 1950, with its last sitting in December 1950.
