The Ngauranga Gorge is in the Wellington Region of New Zealand. State Highway 1 runs through the gorge, a vital link between central Wellington City and its northern suburbs and Porirua City and the Kāpiti Coast; it is the main route north out of Wellington. It is 2 kilometres (1.2 mi) long and has a grade of approximately 8 percent. Sixty-five thousand vehicles a day[when?] travel through it, and it connects the Wellington Urban Motorway with the Johnsonville–Porirua Motorway.
The name is derived from the former Ngā Hauranga pā at the foot of the gorge. Its spelling was simplified after the Second World War.
