Roads of National Significance

New Zealand's roads of national significance

The government has identified some of New Zealand's most essential routes as requiring significant investment.

The seven roads of national significance (RoNS) identified in the GPS are:

  • Puhoi to Wellsford – State Highway (SH1)
  • completion of the Auckland Western Ring Route – SH20/16/18
  • the Auckland Victoria Park bottleneck – SH1
  • the Waikato Expressway – SH1
  • the Tauranga Eastern Corridor – SH2
  • the Wellington Northern Corridor (Levin to Wellington) – SH1
  • Christchurch motorway projects.

The RoNS represent a substantial change in planning for major national transport infrastructure in New Zealand. They are lead infrastructure - proactive improvements that encourage economic growth. In the past, improvements have tended to be reactive and focused on improving transport networks to keep pace with growth.

This NLTP aims to advance the delivery of the identified RoNS so that they are substantially completed within the next 10 years. However, as this will require funding beyond that currently identified, alternative financing options are likely to be explored.

All the RoNS projects are at various stages of development, ranging from Auckland's Puhoi to Wellsford four-laning (which is at the initial development stage) to the Victoria Park Tunnel, which is nearing construction.

RoNS projects will be complemented by improvements to key arterial roads and urban public transport networks. The NZTA is also working closely with local government to ensure the full benefits of the RoNS are realised.

The diagram below provides an indication of expenditure on the RoNS over the next ten years and an indication of funding available from the NLTF and tolls.
