The New Zealand state highway network consists of 11,235-kilometres of rural and urban roads. The total length of the rural state highway network assessed is 10,187-kilometres. Star Ratings have been provided for 10,002 kilometres of the New Zealand state highway network. Star Ratings have not been provided for the remaining 185-kilometres because the section lengths are less than three-kilometres, underlying base rating data was unavailable or road construction work was being carried out. Star Ratings are based on a section length of five-kilometres (with a range between three-kilometres and seven-kilometres).

Summary

The following table shows the overall Star Rating results for New Zealand using two methods:

  • the actual Star Ratings given to the rural state highway network in New Zealand
  • the vehicle kilometres travelled for each Star Rating. This shows the percentage of traffic driving within each of the given Star Ratings.

Of the 10,002-kilometres assessed:

  • 39% rated 2-Star
  • 56% rated 3-Star
  • 5% rated 4-Star

There are no 1-Star or 5-Star roads over a five-kilometre length.

Distribution of Star Ratings

This table shows the Star Rating results for each of the 15 regions. The results illustrate what percentage of the rural state highway network fall within each of the 5-Star Rating bands.

Star Ratings By Vehicle Kilometres Travelled

This table shows the Star Ratings for each of the 15 regions based on vehicle kilometres travelled.

Of the 10,002-kilometres assessed:

  • 33% of annual vehicle kilometres travelled is on 2-Star roads
  • 40% of annual vehicle kilometres travelled is on 3-Star roads
  • 28% of annual vehicle kilometres travelled is on 4-Star roads.

Key Safety Features

This tables provides a snapshot of the key safety features that have a large influence on safety outcomes over New Zealand’s rural state highways.

  • 5% of the network is median divided
  • 20% has forgiving and safe roadside conditions
  • 96% has good delineation
  • 98% has wide lanes
  • 13% has good sealed shoulder width
  • 72% has good horizontal alignment
  • the network has an intersection frequency of one intersection for every two-kilometres of travel.

The reported attribute statistics are based on 100-metre road section data. The sum of the individual region’s values may not add up to the total due to rounding to the nearest whole number.

Percentages may not add up to 100% due to rounding.
