RTC chairman Martin Williams, a Napier lawyer, says the concept of legal action, for which he still believes there is legal ground, is on hold rather than "abandoned", but with the "problem" that if a High Court result went against NZTA, it could ultimately still make the same decision.
Regional leaders produced a position statement, saying they were "united in our deeply held concern that Waka Kotahi is literally putting the brakes on our regional economy, through its approach to speed management on the state highway network."
Goodspeed's petition asked Parliament to rescind its decision to permanently lower the speed limit on SH5, between Rangitaiki and Esk Valley. She believed NZTA consultation was inadequate and did not consider negative economic and social effects.
Describing it as "national policy by stealth," and challenging NZTA advertising campaigns as "wasteful", she wanted a debate in the House about the appropriate balance between measures to improve road safety and the social and economic costs of safety changes.
The integrity of the consultation has also been questioned by mayors and other community leaders, but NZTA told the committee an evaluation of the change is planned for March next year.
Although the scope was still being finalised, it would consider the safety, economic, and social implications, the committee report said.
Waka Kotahi also reaffirmed it would carry out a programme business case to "set out a long-term vision for SH5 and inform future improvements to address safety and resilience along the corridor".
The committee said Goodspeed's submissions explained "very effectively" the economic and social costs that could impact residents and workers in the areas affected by the reduced speed limit.
"Nevertheless, we support the emphasis on road safety embodied in the Road to Zero strategy," it said. "We look forward to learning about the results of the evaluation."
