The Ngauranga Interchange at the foot of the Ngauranga Gorge is a major interchange in the suburb of Ngauranga, in Wellington, New Zealand. The Ngauranga Interchange connects State Highways 1 and 2 with each other and also to Hutt Road for access to the interisland ferry terminals and alternative access to central Wellington. The incremental launching method used for constructing the interchange was the first time this technique had been used in New Zealand.
The majority of traffic in and out of Wellington uses this interchange. It is the southern terminus of State Highway 2.
