West Coast councils have spent close to half a million dollars working on speed limit changes that the coalition Government has now binned.
The West Coast regional transport committee was forced to withdraw its draft regional speed management plan on Thursday, after Transport Minister Simeon Brown signed a new Speed Limit Rule that overrides it.
It also strips councils of their ability to submit their own safety plans in future, staff have reported.
The four councils on the West Coast had written a single regional plan to improve efficiency and coordination, including some small, fixed-speed zones around schools.
It also proposed to lower speeds limits on several roads causing concern for locals.
But the Minister's new Rule allows only variable limits outside schools and requires councils to reverse any speed limits that were changed.
The draft West Coast transport plan was publicly consulted on over four weeks in March and April, and cost the Regional Council $78,000 to develop - not including staff time.
But transport committee chair Peter Ewen says there were bigger costs for the three district councils, in completing their sections of the plan.
"Buller spent $172,000 and Westland would have been close to that; when you add them all up, you'd be pushing $500,000, and it's gone."
There was no way the government would be reimbursing councils for the wasted time and money, Ewen said.
The speed limit changes made by the previous government had been "a little rushed", he said.
"But if there's another change of government in a few years, are we going to be spending more money we can't afford - all for nothing, because the incoming government throws this out?"
It would be nice if the major parties could agree on policy like speed limits, Ewen said.
"We live in hope, but meanwhile the ratepayers have to grin and bear it."
Under the latest changes, reduced speed limits of 30kph will apply to urban schools during high-risk pick-up and drop-off times, and there will be a similar limit of 60kph or less on roads that pass rural schools.
The speed limit on roads of national significance will rise to 120kph.
The Minister has said it made no sense to slow down a tradesperson passing a school at 5am on the way to work, and the changes would improve traffic flows.
A staff report to this week's regional transport committee meeting said district councils could still submit individual speed management plans.
But they would have to do a separate cost-benefit analysis for each road being considered for a speed change, followed by a six-week community consultation.
The government had now removed the NZTA subsidies that previously applied to that work, policy manager Max Dickens reported.
And there was still a significant chance that a council's proposed change would be rejected by the director of land transport if the proposed limit did not abide by the government's new speed limit classifications, he said.
The new National Rule meant that all the work on the draft West Coast speed management plan was now a sunk cost.
Safety outcomes were likely to become worse and the largest risk was that councils would lose the ability to control the roads they had authority over, Dickens said.
The Transport Minister recently told Local Democracy Reporting that Kiwis had rejected a blanket and untargeted approach to reducing speed limits.
Consultation highlighted "broad support" for the Government's new rule with 65 per cent of submitters supporting the reversal of blanket speed limit reductions, Brown said.
The new speed rules apply from 1 July next year.
