Appended to the petition is Goodspeed's explanation that she believes the speed reductions "should instead be implemented at known crash spots (notably Te Pōhue and Te Hāroto) supported by a comprehensive upgrade plan".
"A blanket approach to speed reduction on SH5 will negatively impact the region's economy, residents and visitors, while doing nothing to address the road's physical issues. Public opposition, the positive impacts achieved through targeted maintenance and safety works, and police's 'Stay Alive on 5' road safety campaign have been ignored," she said.
Petition pages of Parliament's website state the time taken by a committee to investigate a petition and finish its consideration can vary widely.
The petition pages say committees typically request evidence relating to a petition from a wide range of people and organisations, and it can take time to collect and consider evidence.
If the committee makes recommendations to the Government when it reports to the House, the Government has 60 working days to respond.
The road had a bad reputation for fatalities, with eight deaths in the space of 10 months from December 2019 to October 2020.
However, since police, Waka Kotahi and road safety agencies launched the "Stay Alive on 5" campaign 15 months ago, there have not been any deaths.
Advocates are planning a private sit-down meeting with MPs later this month to discuss their concerns.
Goodspeed said she believed Waka Kotahi had not followed due process and there would be negative impacts for businesses across the country.
"There will be ripple effects from this decision on the trucking community, on availability of trucking hours to get groceries from Auckland to Hawke's Bay."
She also had been told it could reduce logging truck income by 25 per cent.
Opposition Taupo MP Louise Upston, who also keeps a watch on Hawke's Bay for the National Party caucus, said she is "strongly in favour of NZTA reversing this decision and would gladly present the proposed petition to Parliament on behalf of our local communities and State Highway 5 road users."
"One of the top issues for both my electorate of Taupo and Hawkes Bay is SH5 which connects them," she said. "Instead of making improvements to this important regional state highway, unsurprisingly the temporary lower speed limits are to become permanent."
