New Zealand State Highway network

The New Zealand State Highway network is a network of roads covering the North and South Islands. Currently about 85 roads have a "State Highway" designation: Transit New Zealand administers them. The speed limit for most State Highways is 100 km/h, with reductions when a State Highway passes through a built-up area.

The highways were originally designated on a two-tier system, National (SH 1-8) and Provincial, with national highways having a higher standard and funding priorities. Now all are State Highways, and the network consists of SH 1 running the length of both main islands, SH 2-5 and 10-58 in the North Island, and SH 6-8 and 60-99 in the South Island.

State Highways are marked on the side of the road by red shield-shaped signs with white numbering (shields for the former Provincial Highways were blue). Road maps usually use this convention.

From 2001 information, the busiest stretch of SH 1 was the Auckland Harbour Bridge, with over 150,000 cars crossing (either way) each day. The least busy parts of the network (excluding off-ramps and on-ramps) are parts of SH 43 north of Whangamomona, which get fewer than 200 cars (counting both directions) in a day. Some of the lesser trafficked highways still contain some unsealed sections.

History of the State Highways

Since the 1980s State Highways have been the responsibility of Transit New Zealand, a state-owned corporation. Since Transit NZ funds only State Highways, city or district councils have sometimes negotiated reallocation of highway routes within their boundaries in order to let Transit part-fund major upgrades to the regional roading network. For example, SH 1 historically ran through the centre of Christchurch, but is now the Christchurch bypass route, while SH 73 and 74 have been extended further into the city to cover major arterial routes.

Highway routes around Tauranga and in the Napier/Hastings region have undergone major changes in recent years.

Distance Markers

State Highways are marked with posts at irregular intervals giving the distance in kilometres from the start of the highway. All bridges on the network have, at either end, small plaques showing the distance from the start of the highway, usually in the form of a number in kilometres, an oblique stroke, and a further number in hundreds of metres. A plaque marked 237/141, for example, would indicate that the bridge is 14.1 km past a set distance post, that post being 237 km from the start of the highway.

As of 2004 these plaques are gradually being replaced by a new system which gives each bridge a single number showing the distance from the start of the highway in hundreds of metres. Under the new system the bridge used as an example above would show a plaque with its name and the number 2511, as it is 251.1 km from the start of the highway.

In this way, travellers can accurately assess their location, and road authorities can identify each bridge uniquely.

State Highway 1

SH 1 starts at Stirling Point, 1 km south of Bluff, and then goes north to Invercargill, and north-east to Gore. It runs due east to Balclutha, then up through Milton to Dunedin. The highway continues along the east coast past Palmerston, Oamaru and Timaru, moving inland a bit and then north-east through Ashburton toward Christchurch, which it now bypasses. After traversing the northern end of the Canterbury Plains it winds through some ranges culminating in the Hundalees before returning to the spectacular, mountain-hugging coastline around Kaikoura. SH 1 then continues up the coastline for 80 km before diverting inland to Blenheim and up to Picton at the north of the South Island, terminating at the inter-island ferry terminal.

Ferries cross Cook Strait to the capital city of New Zealand, Wellington. There have been calls for the ferries to be classified as part of the State Highway network, in the belief that this would increase the Government's powers to intervene and keep the ferries running at times of industrial action.

The northern part of SH 1 commences at Wellington Airport and runs through the city and up the Ngauranga Gorge to the western coast. Difficult terrain and a large number of satellite towns make this an area of considerable congestion and a high accident rate. SH 1 passes through Levin and shares the route of SH 3 for a 6-km section between the small towns of Sanson and Bulls as it crosses the Rangitikei River. Turning north-east, it follows the river to Taihape, then climbs to the central plateau at Waiouru. The stretch between Waiouru and Turangi is known as the Desert Road, and is frequently closed by snow in winter. There are spectacular views of the three volcanoes Mount Ruapehu, Mount Ngauruhoe and Mount Tongariro.

Turangi is near the southern tip of Lake Taupo and the highway skirts the eastern shore. North of Taupo, the highway turns north-westwards and descends through extensive tracts of plantation forest to Tokoroa and Tirau. Here it joins the Hamilton - Rotorua route and follows the course of the Waikato River through Cambridge to Hamilton. A $NZ500 million project to convert the entire 160 km between Cambridge and Auckland to a four-lane divided carriageway is about one third complete as of late 2003.

From Auckland the highway tends to follow the eastern side of the Northland peninsula, passing through Warkworth, Wellsford, Whangarei and Kaitaia. The highway ends at Waitiki Landing, from where SH 1F - designated in 2004 - runs to Cape Reinga.
