List of motorways and expressways in New Zealand
This is a list of motorways and expressways in New Zealand, including some proposed and under construction. There are currently 363 km of motorways and expressways in New Zealand, with another 124 km planned for development by 2022.
Expressways in New Zealand are usually dual carriageway roads and may have full or partial control of access. They are generally high standard all-purpose roads that cater mainly for through traffic and do not have any traffic restrictions imposed on them. Intersections may be at-grade or grade separated.
Motorways in New Zealand have certain traffic restrictions applied, to provide a better vehicular traffic operating environment. The traffic operating restrictions normally applied under a motorway designation are no stopping and a ban on all animal, pedestrian and cycle traffic.

When completed, it will bypass the existing two-lane State Highway 1 through Raumati, Paraparaumu, Waikanae and Otaki. The section from Mackays Crossing to south of Raumati was completed in 2007 with the grade separation of the Mackays railway level crossing.

Christchurch Northern Motorway (SH 1)Edit
From north of Kaiapoi over the Waimakariri River through to the northern suburb of Belfast. Its southernmost interchange (Kainga/Marshland) is unusual in that northbound traffic merges from the right, while southbound traffic is carried on a large loop to the right up and over the onramp. The reason for this design was to accommodate a future southern extension into central Christchurch, with the northbound onramp being the first part of the northbound carriageway. Northbound there are three more interchanges; Tram Road (Oxford), north off, south on; Kaiapoi (diamond interchange); and Lineside Road (SH 71 to Rangiora), north off, south on. It is dual carriageway from Belfast (Main North Road) to Lineside Road, single lane each way with no median strip to Woodend.
Christchurch Southern Motorway (SH 76)Edit
Short motorway bypassing a part of southern Christchurch city. Lost its status as a motorway after plans to extend the original section (between Curletts Road and Barrington Street, which was built in the early 1980s) stalled. Since 2012, the road has been extended from Curletts Road to Halswell Junction Road with the original section widened to four lanes and interchanges at both Curletts Road and Barrington Street), thereby regaining motorway status.
Christchurch-Lyttelton Motorway (SH 74)Edit
From the intersection of Ferry and Dyers Roads along Tunnel Road through the Lyttelton Tunnel to the intersection of Norwich Quay and Simeon Quay. It is single lane with interchanges at Bridle Path and Port Hills Road. There is a passing lane southbound from the Port Hills Road interchange.
