The New Zealand state highway network is the major national highway network in New Zealand. Nearly 100 roads in the North and South Islands are state highways. All state highways are administered by the NZ Transport Agency.
State Highway 1 is the longest and most significant road in the New Zealand road network, running the length of both main islands. It appears on road maps as SH 1 and on road signs as a white number 1 on a red shield, but it has the official designations SH 1N in the North Island, SH 1S in the South Island.
State Highway 65 is a New Zealand state highway in the South Island. It is 71 km long and runs south to north down the Maruia river valley from SH 7 at Springs Junction, 15 km west of the main divide at the Lewis Pass, to SH 6 in the Buller Gorge, 11 km west of Murchison. It forms part of the most direct route between Christchurch and Nelson. It takes its name from a small settlement toward its northern end.
The Dunedin Southern Motorway is the main arterial route south from the South Island city of Dunedin, part of New Zealand's State Highway 1. Despite its name, only a portion of the route is officially classified as motorway. The route is the southernmost section of median-divided highway in the world.
State Highway 7 is a major New Zealand state highway. One of the eight national highways, it crosses the Southern Alps to link the West Coast Region with Canterbury and to form a link between the South Island's two longest highways, State Highway 1 and State Highway 6. Distances are measured from east to west with the major junction list going from east to west.
State Highway 6 is a major New Zealand state highway. It extends from the Marlborough region in the northeastern corner of the South Island across the top of the island, then down the length of the island, initially along the West Coast and then across the Southern Alps through inland Otago and finally across the Southland Plains to the island's south coast. Distances are measured from north to south.
State Highway 5, one of New Zealand's eight national highways, runs from State Highway 1 at Tīrau, in the south Waikato, to State Highway 2, close to the Hawkes Bay coast at Bay View, 10 km north of Napier. It is the second shortest of the national highways.
State Highway 3 (SH 3) is one of New Zealand's eight national state highways. It serves the west coast of the country's North Island and forms a link between State Highway 1 and State Highway 2. Distances are measured from north to south.
State Highway 2 runs north–south through eastern parts of the North Island of New Zealand from the outskirts of Auckland to Wellington. It runs through Tauranga, Gisborne, Napier, Hastings and Masterton. It is the second-longest highway in the North Island, after State Highway 1, which runs the length of both of the country's main islands.

It is 117 km long and runs between the settlements of Renwick and Kawatiri Junction via Saint Arnaud, providing a bypass of the city of Nelson. Despite being a convenient link between the West Coast and Marlborough, and being a relatively straight highway along most of its length, it is only classified by the NZTA as a secondary collector highway.
State Highway 85 (SH 85) is a South Island state highway in New Zealand, servicing the Maniototo Plains and the North and Central Otago regions of the South Island between the major settlements of Alexandra and Palmerston. It is wholly two lane and passes through some of the most extreme climatic regions in New Zealand. The highway is known colloquially as "The Pigroot". Though there is no definitive explanation for this name, A. W. Reed, in his book Place Names of New Zealand, mentions an incident during John Turnbull Thomson's survey of inland Otago in which local wild pigs were so unafraid of humans that a huge boar approached his party and rubbed its nose against that of Thomson's horse.
State Highway 57 (SH 57) is a New Zealand state highway, linking State Highway 1 north of Ohau to State Highway 3 east of Ashhurst, via Levin, Shannon, Massey University and the southern suburbs of Palmerston North. The highway connects State Highway 1 traffic coming north from Wellington to the city of Palmerston North, and further to the Manawatū Gorge, allowing passage to the eastern side of the North Island and to the twin cities of Napier and Hastings. The highway is classified by the NZTA as a national strategic road.
