General Information:
State Highway 1 is the main route throughout New Zealand, covering both the north and south islands. It is the most important and also the longest numbered route in the country.
The route is a mix of 2-lane rural highway, multilane urban arterial road, expressway and motorway standards. It passes through rural, commercial and industrial zones as well as through forested areas. The route is paved the entire length. A 7 km section of the route is tolled (Northern Gateway Toll Road) 1, between the areas of Silverdale and Johnstone Hills north of Auckland. 2 The route also features the Auckland Harbour Bridge over Waitemata Harbour. SH1 is broken into two segments by the Cook Strait, which is serviced by the Interislander Ferry between Wellington and Picton.
State Highway 1 between Tūrangi and Waiōuru (the Desert Road) is the highest pass on the state highway network at about 1074 metres above sea level. 3

History:
- North Island:
- 30 May 1959: After decades of debate and petitions, the Auckland Harbour Bridge across the Waitematā Harbour opened to traffic. Before it opened, the only way passenger vehicles could cross the harbour was by ferry. Cars and taxis were tolled 25¢, motorcycles 15¢, buses 50¢, and 40¢ for commercial vehicles. 5
- 1966–1969: Clip-on lanes were added to the Auckland Harbour Bridge at a cost of $7.4 million, doubling the number of lanes from four to eight to increase capacity and ease congestion. 5
- 31 March 1984: Tolls were officially abolished on the Auckland Harbour Bridge. 5
- 1990: A moveable lane barrier system that includes a barrier and two machines is installed on the Auckland Harbour Bridge to prevent head-on collisions and manage traffic flows in the 'tidal' morning and evening peak system. 5
- August 2008: A two-and-a-half-year project to strengthen the Auckland Harbour Bridge's clip-on lanes started. 5
- 25 January 2009: Northern Gateway Toll Road opened to traffic. The 7.5 km route extends the Northern Motorway from the Ōrewa turnoff to Pūhoi, bypassing the seaside townships of Ōrewa, Hatfield's Beach, Waiwera, and the Wenderholm Regional Park. The toll road features Johnstone's Hill Twin Tunnels, which are 15 metres apart, 380 metres long, 12 metres wide, and 9 metres high. They were built to carry two lanes each, plus a shoulder and an emergency pathway. 6
- 4 September 2011: The 1.3 km extension of Kamo Bypass in Whangārei was officially opened. 7
- 1 October 2012: Widening works commence on SH1 (also known as Western Hills Drive) in central Whangārei. 8
- 2015: Widening and realignment work begins on SH1 near Akerama Road, near Hūkerenui, 35 km north of Whangārei. 9
- November 2014: Work starts on adding an additional northbound lane from Ellerslie-Panmure Highway on-ramp to after the main highway overbridge. 10
- August 2015: Work commences on the 27 km Transmission Gully Motorway between the Kāpiti Coast and Wellington. 11
- 28 August 2015: Work commenced on the Huntly section of the Waikato Expressway. 12
- 27 October 2015: Work on safety improvements on State Highway 1 on the Brynderwyn Hill south of Whangārei. It includes widening the road, removing tight corners, and installing a wire rope barrier to separate north and southbound traffic. 13
- 16 December 2015: Completion of the 16 km Cambridge section of the Waikato Expressway, starting south of the Tamahere interchange and ending around 2.5 km south of Cambridge. 14
- 12 July 2022: Completion of the eastern bypass of Hamilton. 15 SH1 was later relocated onto the new alignment, and the old route renumbered to SH1C.
- South Island:
- 1912: The Ōpaoa River Bridge, between Picton and Blenheim on the northern edge of Blenheim, was designed. 16
- 1917: The Ōpaoa River Bridge opened to traffic. The bridge is 170 m long. 16
- 1932: Construction of the Dashwood Overbridge between Blenheim and Seddon. 17
