Roads of National Significance
Roads of National Significance is a programme of major transport projects aimed at improving key transport corridors to enhance economic growth, productivity, and road safety in New Zealand. The programme was first introduced in 2009 until 2017 by the Fifth National Government, and reintroduced by the Sixth National Government in 2024.
History
Fifth National Government, 2009–2017
RoNS were first announced on 20 March 2009 by Transport Minister, Steven Joyce, saying they were, "singled out as essential routes that require priority treatment". They were described as "routes that are critical to improving economic productivity and growth... The focus is on moving people and freight between and within these centres more safely and efficiently". Later in 2009, Prime Minister John Key, announced $11 billion in new State Highway investment over the coming decade, saying National wants to significantly improve our road network and help unclog New Zealand's growth arteries.Between 2012 and 2015 petrol taxes and road user charges rose 9 cents a litre to pay for RoNS. The proportion of the transport budget for new and improved state highways rose from 23.4% in 2009/2010, to 61.8% in 2011/2012. Funding for other transport, such as repairs and footpaths, fell by 26.1%. In 2013 that led to the Auditor General reporting a risk that prioritising RoNS created pressures on other road maintenance. From 2015 to 2020 average seal age rose from 6.86 to 7.96 years and average remaining seal life dropped from 2.18 to 1.23 years.
The seven RoNS projects were:
- Puhoi to Wellsford – SH1
- Completion of the Auckland Western Ring Route – SH20/16/18
- Auckland Victoria Park bottleneck – SH1
- Waikato Expressway – SH1
- Tauranga Eastern Corridor – SH2
- Wellington Northern Corridor (Levin to Wellington) – SH1
- Christchurch motorway projects
There have also been defects in construction, which have required costly repairs and led to questions over how contracts were awarded.
Some of the RoNS had low cost benefit ratios. In a written answer in 2017, the Minister of Transport, Simon Bridges, said the Warkworth to Wellsford motorway would return a benefit of 25 cents for every dollar spent.

The total cost of RONS projects that are either complete, or under construction, is $9.6 billion, including Auckland's Northern Corridor project. That provides for around 250 kilometres of new or significantly upgraded roads at an average cost of around $35 million per kilometre.
