State Highway 1 (SH 1) is the longest and most important of the State Highways of New Zealand. It runs in a north -south direction along over both main islands and therefore has two sections: SH 1N in the North Island and SH 1S in the South Island. However, he appears on road signs and in maps as SH 1 is the total length of the road 2047 km, of which 1106 km on the north and 941 km on the South Island. The kilometer marking is done for each island separately from north to south.

The SH 1 is for the most part a road with one lane in each direction with intersections and property accesses, ie equivalent to about a federal highway / main road. In these sections there are at intervals passing lanes. Five percent are expanded to two lanes. In the vicinity of Auckland, Wellington, Christchurch and Dunedin total of six percent of the road was extended as a freeway.

North Island

The highway begins in the north at Cape Reinga. The first 20 km are unpaved. The road is now the east side of the Peninsula Aupouri to Awanui. Here branches off of State Highway 10. This runs close to the north coast and flows back into the Pakaraka SH 1 After another five miles of SH reaches 1 Kaitaia and now runs in a southeasterly direction diagonally across the north of the Northland Peninsula and in the area of ​​the Bay of Islands. Just before he reached them, branches in Ohaeawai of State Highway 12 to the west and the SH 10 combined eight kilometers away near Pakaraka again with the SH 1

Now, the road runs inland about 10-20 km from the east coast to Whangarei. Here, the State Highway 14 towards Dargaville goes off. The SH 1 runs further south to Brynderwyn where the SH 12 again joins the SH 1 and finally to Wellsford. Here branches off running on the west coast of the south of the Northland Peninsula State Highway 16. The SH 1 now runs 20 km in a southeasterly direction to Warkworth and now, 26 km south to Orewa. While the SH 1 remains on the coast, bypassing the SH 1A Orewa on the land side. Here the SH 1 becomes the Auckland Northern Motorway. This passes through to North Shore City Auckland belonging suburbs and crosses on the Auckland Harbour Bridge, the entrance to the Waitemata Harbour in downtown Auckland. This section is considered busiest and most often affected by congestion road of the country. Known as the Central Motorway Junction motorway interchange between SH 1 and SH 16 was traveled in March of more than 200,000 vehicles per day. A particular bottleneck presented here through years of road in Victoria Park in central Auckland dar. On 14 November 2011 the Victoria Park Tunnel was therefore opened. The traffic has been running in two parts: In the north, the vehicles are routed through the single-tube tunnel, the south runs the traffic continues above ground on the old route. For the above ground route to be rebuilt until January 2012, so that only one carriageway is available.

From Auckland motorway passes to the south and is called here Auckland Southern Motorway. 50 km south of the harbor bridge it becomes a dual carriageway with two trip strips. Shortly thereafter branches of State Highway 2 from the east, while the SH 1 runs south to Mercer. From there it follows the course of the Waikato River through Hamilton. Here, the State Highway 3 branches off to the southwest, while the SH turns to the southeast and along through Cambridge and Lake Karapiro. A NZ $ 650 million expensive project for the expansion of the 160- km section between Auckland and Cambridge into a dual carriageway, the Waikato Expressway was completed in half in early 2006. In Tirau of State Highway 5 begins towards the east, the SH 1 runs south through Tokoroa and extensive forest areas to Taupo on the northeastern shore of Lake Taupo. He roams the eastern shore of the lake to Turangi at the southern end of the lake.

South of Turangi crosses the street, the Central Volcanic Plateau and the Desert Rangipo to Waiouru. This 52 km long section is as Desert Road ( Desert Road ) known and often closed in winter because of too much snow. The highest point of the Desert Road is located 1074 m above sea level, this is the highest point of the entire New Zealand highway network. From the road there are views of the three volcanoes Mount Tongariro, Mount Ngauruhoe and Mount Ruapehu. From Waiouru, the road ascends from Taihape and Mangaweka, while the south-west direction extending Rangitikei River. The SH 3 extends over a distance of three kilometers between Bulls and Sanson, together with the SH 1 via the Manawatu Plain. After passing through the SH 1 Foxton and Levin.

In Ohau, four kilometers south of Levin of State Highway 54 branches off to the northeast. The SH 1 follows which narrowing coastal plain on the west coast by Otaki, Paekakariki and Plimmerton. Difficult terrain and a large number of satellite towns make the track sensitive to congestion and accidents. From the Porirua road becomes the Johnsonville - Porirua Motorway and passes through Wellington's northern suburbs. At the end of the Johnsonville - Porirua Motorway at Newlands SH 1 becomes the Centennial Highway. This runs through the Ngauranga Gorge. Two kilometers later, the SH 1 and State Highway 2 take SH 1 is now the inner city Wellington Urban Motorway. The highway ends in Willis Street and continues through the eastern suburbs. It ends in a roundabout at the entrance to Wellington International Airport.

The connection to the southern part of the highway is done by ferry across the Cook Strait, which operate between Wellington and Picton in the Marlborough Sounds. These are not part of the highway system, although there were advances in this direction, to give the government more control for possible strikes.

South Island

From the ferry terminal in Picton, the road climbs steeply and crosses a mountain saddle in the valley of the River Tuamarina. It rises from the valley of this river and cross the Wairau Plain. From Blenheim it largely follows the coastline and passes it the towering Kaikoura Ranges. This section is one of the most beautiful. The Pacific is located here on the one hand, the 2500 m high peaks on the other. After Kaikoura the road turns inland, winds through the Hundalee rank and then impinges on the north end of the Canterbury Plains.

The highway passes Waipara where the State Highway 7 branches and after a further seven miles Amberley. He is then to Christchurch Northern Motorway. This highway passes Kaiapoi and ends north of Styx. The SH 1 bypasses Christchurch in the northwest. South of the city he runs almost straight across the wide alluvial fan of the Canterbury Plains. In Rakaia he crossed the Rakaia River on the longest road bridge in the country and then reaches Ashburton. In Timaru, he again reached the coast. Between Ashburton and Timaru, he crosses the island Rangitata Iceland in Rangitata River.

From Timaru, the road follows the coast, crossing the Waitaki River and reached Oamaru. Now she crosses the hills of the northern Otago. South of Waikouaiti, the road climbs steeply up the hill Kilmog and drops back to the coast. Then she rises again and becomes a highway in the northern suburbs of Dunedin. There she falls steeply, passing through the University of Otago and the city center. For a large part of the route through Dunedin, the highway consists of two separate roads for the directions that are part of the Einbahnstraßennnetzes the city. A two-lane highway through the southern suburbs to the junction with State Highway 87 in Mosgiel. The SH 1 runs further to the southeast direction Balclutha, Clutha River crosses there the on the Balclutha Road Bridge and then turns west to bypass the steep hills of the Catlins. In Gore, he runs back to the south and southwest to Invercargill, where it ends at Stirling Point, one kilometer south of Bluff.

Route changes

A larger section between Allanton and the Taieri River was realigned already in the 1970s. Since then, Transit New Zealand in 1989, the management of State Highways took over, the route was changed at some other places. In Whangarei, Hamilton, Christchurch and Timaru, the leading through the city center route was moved to the suburbs, the old route is still used as a street or received in Christchurch a new number as Highway. For the Dunedin Southern Motorway, a bypass around Fairfield was built.

In the south of the South Island more particularly tortuous sections were replaced in order to avoid sharp turns and improve road conditions. These include sections on Normanby, near Timaru, Waianakarua, Tumai, Palmerston and on the Dunedin Northern Motorway at Waitati.


The SH 1 has two branch lines on the North Island. The SH 1A bypasses Orewa, the SH 1B deal between Taupiri Hamilton and Cambridge.
