The New Zealand Centennial Exhibition took place over six months from Wednesday 8 November 1939 until 4 May 1940. It celebrated one hundred years since the signing of the Treaty of Waitangi in 1840 and the subsequent mass European settlement of New Zealand. 2,641,043 (2.6 million) visitors attended the exhibition.
The New Zealand Government staged the exhibition with assistance from local government, New Zealand industry and the New Zealand public. The exhibition received support from the United Kingdom, Australia, Canada, Fiji and other Pacific islands who either constructed their own pavilions on site or had displays in one of the exhibition buildings.
