Plan to restore higher speed limit between Nelson, Blenheim

The main route between Nelson and Blenheim could soon be back to 100kmh under a proposal by the government to alter how speeds are set.

Last week, the government opened consultation on its draft land transport rule which aims to put a stop to blanket speed limit reductions.

“The previous government’s untargeted approach slowed Kiwis and the economy down, rather than targeting high crash areas of the network,” Minister of Transport Simeon Brown said in a statement.

The proposal would reverse speed changes made since January 1, 2020 on local streets with widespread 30kmh speeds around schools, urban connector roads, and rural state highways.

This could mean that 100kmh limits could return on stretches of State Highway 6 between Wakefield and Hope, and between Nelson and Blenheim.

If Waka Kotahi can demonstrate public support for the reduction in some sections, such as hilly or windy areas, the lower speed limit can be retained in those locations.

However, the agency would be required to undertake new consultation on the changes in line with additional requirements contained within the draft rule.

The highway between Blenheim and Nelson was classified as a high-risk rural highway before speeds were reduced.

In the 10 years between 2009 and 2018, 20 people died and 92 were seriously injured. Of these, 19 of the deaths and 87 of the serious injuries were in areas with a 100kmh speed limit.

The route has seen a 93 percent reduction in fatal and serious crashes on since the reductions were introduced.

In the same period, there were 98 crashes on the section between Wakefield and Hope, in which three people were killed and 18 sustained serious injuries.

Tasman’s deputy mayor Stuart Bryant, chair of Nelson Tasman’s transport committee, said the impacts of the changes on the region’s speed management plan weren’t yet known, “but at first glance, the draft rule would appear to make it more difficult and costly to change speed limits”.

The draft rule would introduce a binding schedule of speed limits for each road type, while councils would have to undertake cost-benefit analyses on changing the speeds for each affected road, enact variable rather than permanent speeds outside schools, and meet ministerial objectives.

The region’s two councils are currently in the process of creating a speed management plan which was consulted on over the summer.

Though guidance from the government has been opposed to blanket speed reductions, Bryant said the committee will look to lower speeds where its being specifically called for by residents.

“Our community has provided strong feedback that they want to see some changes, especially around schools, and we’d like to progress those if possible.”

Otherwise, the changes currently being proposed by the government don't appear to affect local roads controlled by either council.

Tasman District Council has said that no local roads will be affected by the draft rule, with recent changes, such as the reduced speed limit outside of Motueka Steiner School on Robinson Rd, already being accommodated by the proposal.

This situation is mirrored in Nelson City.

Though the city centre was reduced from 50kmh to 30kmh in 2020 and could be classified as a blanket reduction, the affected roads aren't of the type specified by the government as needing to be reversed.

“There is a risk this could change once the rule is modified by central government from draft to final, but as it stands we feel confident that these changes will remain in place,” said David Light, the city council’s acting group manager infrastructure.

“However, council may find it harder to bring in similar changes in the future under the draft rule.”

Light added that reverting speed limits would be relatively simple and inexpensive unless consultation was required which would be “more time consuming and costly to the ratepayer”.
