State Highway 8 is one of New Zealand's eight national highways. It forms an anticlockwise loop through the southern scenic regions of the Mackenzie Basin and Central Otago, starting and terminating in junctions with State Highway 1. Distances are measured from north to south. For most of its length SH8 is a two-lane single carriageway, with at-grade intersections and property accesses directly off the road, both in rural and urban areas.
