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.
U.S. Route 7 is a north–south U.S. Highway which runs 78 miles (126 km) in the state of Connecticut. The route begins at Interstate 95 (I-95) in Norwalk starting out as an expressway until the Wilton town line. The route then proceeds north as a two-lane highway through Redding and Ridgefield until it reaches Danbury. The route becomes an expressway again, eventually merging with I-84 for a brief period before it turns and proceeds north with Route 202 in Brookfield. The expressway section terminates at an intersection with Route 202 at the Fairfield–Litchfield county line next to Candlewood lake. The route then continues north passing by New Milford as a two-lane highway to the Massachusetts border in North Canaan. US 7 was aligned to its current route around 1930, and since then three sections totaling around 12 miles (19 km) have been upgraded to freeway standards.
State Highway 21 (SH 21) is a short 6.7 kilometre stretch of highway in the North Island of New Zealand. It links State Highway 1, Waikato Expressway at Tamahere and State Highway 3 at Ohaupo. Its main destination is Hamilton Airport and Mystery Creek, where the National Agricultural Fieldays are held.
State Highway 93 is a New Zealand State Highway connecting the Southland township of Mataura with the Western Otago town of Clinton. This provides a slightly quicker route between the cities of Dunedin and Invercargill, as it bypasses the town of Gore. It is roughly 43.2 km long.
Dunedin-Waitati Highway, formerly called Dunedin Northern Motorway, is a two to four-lane limited-access road which provides the main route north from the city of Dunedin, New Zealand. Opened on 14 December 1957, it superseded the narrow and winding routes via Port Chalmers and Mount Cargill. The road is occasionally briefly closed by snowfall in winter.
State Highway 73 is a major east-west South Island state highway in New Zealand connecting Christchurch on the east coast with Cass/Hokitika via the Southern Alps. It is mostly two lane, with some single-lane bridges north of Springfield but is mostly dual carriageway in Christchurch. The fourth and fifth-highest points of New Zealand's state highway network are on this road at Porters Pass and Arthur's Pass respectively.
State Highway 74 is a state highway in New Zealand servicing the eastern suburbs of Christchurch. Mostly two-lane, it is composed of limited-access expressways, with part of the highway as the Christchurch-Lyttelton Motorway, and connects the city to its port town of Lyttelton.
State Highway 77 is a state highway in New Zealand going through the inland parts of Central and Mid Canterbury between the towns of Ashburton and Darfield via the Rakaia Gorge. It is wholly single carriageway with two one-lane bridges at the Rakaia and Selwyn Rivers. One set of traffic lights is found in Ashburton marking the southern terminus of the highway.
State Highway 84 (SH 84) is a South Island state highway in New Zealand. It connects the holiday resort town of Wanaka to State Highway 6, the main north-south highway servicing the western part of the South Island.
State Highway 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 Manawatu 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.
State Highway 88 is a New Zealand State Highway connecting the city centre of Dunedin with Port Chalmers, which is the location of Dunedin's main port facilities and home of one of New Zealand's major container terminals. It is roughly 12 km long.
State Highway 97 (SH 97) is a New Zealand State Highway connecting the settlements of Five Rivers and Mossburn in the Southland region. The highway was gazetted in 2004 to reflect the increasing amount of traffic between the tourist destinations of Queenstown and Fiordland National Park and provides a bypass of the town of Lumsden, where SH 6 and 94 intersect.
State Highway 60 is a state highway servicing the far northwest of the South Island of New Zealand. Running between the settlements of Richmond and Collingwood, it is 116 kilometres (72 mi) long and lies entirely within the Tasman District. It is the northernmost highway in the South Island and is a popular tourist route, servicing Motueka, Abel Tasman National Park, Golden Bay, and Farewell Spit.
State Highway 28 (SH 28) is a New Zealand state highway in the Waikato region. The highway was gazetted in 1997 as a faster route for traffic travelling between SH 1 and SH 29 towards the Port of Tauranga. Prior to the formation of SH 28 the quickest route, only if using state highways, was via Tirau and SH 27. There are no towns on this route and due to the highway being mapped to existing rural roads there are several places were motorists need to give way to traffic from other roads.
State Highway 35 (SH 35) is a New Zealand state highway on the East Coast of the North Island. It is the main highway that services the East Cape of New Zealand as well as many other rural towns such as Hicks Bay, Ruatoria, Tolaga Bay, and the city of Gisborne.
State Highway 39 (SH 39) is a New Zealand state highway that forms a western bypass of the city of Hamilton. Gazetted in 1999, it is a generally quicker route to get between Auckland and New Plymouth as well as connecting to the Waitomo Caves, just south of the SH 39 southern terminus. The southernmost 14 km section has a concurrency with SH 31, as this highway has existed for much longer.
State Highway 15 (SH 15) is a New Zealand state highway in the Northland region of the North Island. It is 126.5 km long and provides an alternative route to SH 1 between the Kaikohe and Whangarei areas; a spur also links SH 1 with the Marsden Point Oil Refinery and Northport.
State Highway 36 (SH 36) is a New Zealand state highway in the Bay of Plenty region in the North Island. It is one of two state highways that form a north-south connection between the cities of Tauranga and Rotorua, SH 36 being the most westerly of the two. It was identified as a quicker route to access the two cities and extensive work was done to upgrade the rural route to state highway quality.
