State Highway 4 is the shortest of New Zealand's eight national highways. It runs north-south across rugged hill country, forming a short cut between two points on State Highway 3 thereby avoiding Taranaki and the coasts of the North and South Taranaki Bights. Distances are measured from north to south.
For most of its length SH4 is a two-lane single carriageway, with at-grade intersections and property accesses, both in rural and urban areas. The NZ Transport Agency (NZTA) classifies SH 4 as a primary collector road, except between National Park (SH 47) and Tohunga Junction (SH 49) where it is classified an arterial road.[1]
