Over six months in 1939 and 1940 Wellington hosted the New Zealand Centennial Exhibition, celebrating a century since the signing of the Treaty of Waitangi. Held on 55 acres of land at Rongotai it featured three exhibition courts, grand Art Deco-style edifices and a hugely popular three-acre amusement park. Wellington attracted more than 2.5 million visitors at a time when New Zealand's population was 1.6 million. Geography Wellington is at the south-western tip of the North Island on Cook Strait, separating the North and South Islands.

On the east the Remutaka Range divides Wellington from the broad plains of the Wairarapa, a wine region of national notability.
