New Zealand Parliamentary Library, Parliamentary library in Wellington, New Zealand.

The New Zealand Parliamentary Library is a Gothic Revival building on Hill Street in Thorndon, north of Parliament House. It was designed by Thomas Turnbull and completed in two stages, in 1883 and 1899, with a floor area of about 63 by 33 metres. It is built of brick made at Mount Cook gaol, has an iron firedoor, and is connected to Parliament House by a passage on its left side.

The library building was constructed in two stages: the western section in 1883 and the eastern section in 1899, and it was first used as a library in 1901. In 1907 a fire destroyed the wooden Parliament House next door and damaged the library, which was repaired. The foyer was damaged by another fire in 1992, and the building was renovated and base-isolated between 1992 and 1995.

The library was known as the General Assembly Library until 1985, when it took its present name and became part of the Parliamentary Service. Writer Katherine Mansfield had borrowing privileges when Parliament was not sitting, taking out works by Heine, Nietzsche, Ibsen and a translation of Bushido. Today access is restricted to those on parliamentary business, though research publications are available to the public.

The building is in central Wellington and easy to reach on foot, with several public transport options stopping close by. Not all areas are open to the public, and access to some collections requires prior permission.

The 1899 building was meant to have three storeys, but costs reached £50,000 and the third was left off. Government architect John Campbell then redesigned the parapets, gables and roof for the lower height, and Thomas Turnbull asked for his name to be removed from the foundation stone.
