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 282.2 km of motorways and expressways in New Zealand, with another 75 km planned for development until 2020.

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.
