Plan Approved 23 July
Subject to final approval by NZTA we'll make some speed limit changes in the coming months.
The following crash statistics have been recorded in the Nelson Tasman area over the past ten years (Waka Kotahi Crash Analysis System database, 2013 – 2022). Note, the data excludes State Highways and there tends to be significant under reporting of minor and non-injury crashes, particularly those involving pedestrians and cyclists. The first table shows total numbers of crashes and injuries for all crashes in Nelson Tasman.
Of the total 171 fatal and serious crashes in urban areas, 121 (73%) involved people outside of motor vehicles (46 cyclists, 36 pedestrians, and 39 motorcyclists).
People outside of motor vehicles are particularly vulnerable to death or serious injury in crashes with motor vehicles at speeds greater than 30km/h. Those involved in crashes resulting in death or serious injury may experience an impact on mental wellbeing.

Local examples of speed limit changes reducing harm
In 2018, the speed limit on SH60 Appleby Highway was reduced from 100km/h to 80km/h in response to safety concerns and relatively high numbers of people being killed or seriously injured. This has resulted in a 62% reduction in fatal and serious crashes.
In 2020, the speed limit on SH6 between Nelson and Blenheim was reduced. This has resulted in a 93% reduction in fatal and serious crashes.
Social cost of crashes
On top of leaving a huge hole in the lives of families, friends, workplaces and communities, road crashes have a huge impact on our society.
The value of statistical life was estimated at
$12.5 million per fatality and $660,100 per serious injury at July 2021 prices.10 There are significant social costs resulting from fatalities and serious injuries.
Death and serious injuries in Nelson Tasman have had a social cost of $429 million over the past 10 years.
Vehicle operating costs and travel time cost
Surveys by Waka Kotahi in 201711 indicated that a 20% reduction in in speed limits in urban areas would be likely to result in an increase in travel time of 9% to 15% (2.7 to 4.5 minutes per 30 minutes of travel), and a reduction in fuel consumption of up to 5%,
In rural areas the results of a 20% reduction in speed limit were a travel time increase of 9% to 13% (5.4 to 7.8 minutes per hour of travel), and a fuel consumption reduction of 14% to 15%.
