Parliament House, in Lambton Quay, Wellington, is the main building of the New Zealand Parliament Buildings. It contains the Parliament's debating chamber, speaker's office, visitors' centre, and committee rooms. It was built between 1914 and 1922, replacing an earlier building that burned down in 1907. Parliament started using the yet to be completed building from 1918. Parliament House was extensively earthquake strengthened and refurbished between 1991 and 1995. It is open for visitors almost every day of the year, and is one of Wellington's major visitor attractions. Parliament House is a Category I heritage building registered by Heritage New Zealand.

New Zealand Parliament Buildings house the New Zealand Parliament and are on a 45,000 square metre site at the northern end of Lambton Quay, Wellington. From north to south, they are the Parliamentary Library building (1899); the Edwardian neoclassical-style Parliament House (1922); the executive wing, called "The Beehive" (1977); and Bowen House. Whilst most of the individual buildings are outstanding for different reasons, the overall setting that has been achieved "has little aesthetic or architectural coherence".
