Speed limits on parts of the Kapiti Expressway could be raised to 110km/h as part of a new Waka Kotahi proposal.
Consultation on raising the speed limit on a stretch of road from 100km/h to 110km/h begins on April 22 and will last four weeks.
However, some sections of the expressway will not be included in the proposal.
"The 3.2km Raumati Straights section of the Kāpiti Expressway, from the northern end of Transmission Gully to the south of Poplar Avenue, doesn’t yet meet some of the safety requirements to be included in this review," according to the Government.
"Planning work is underway to scope and design the necessary improvements, and NZTA will have more to say on work to be started and completed here in due course."
NZTA Waka Kotahi revealed it was considering raising speed limits, on the sections of State Highway 1 north of Wellington, last August.
However, Transmission Gully further south would stay at 100km/h for the time being as there are "remaining works that need to be completed before a speed review can begin".
"Transmission Gully - Te Aranui o Te Rangihaeata is also built to the same high safety and operational standards [as the Kapiti Expressway], and early indications are that the crash numbers reflect the same improvement in safety."
Transport Minister Simeon Brown released details of the proposal today and welcomed the news. National campaigned on speed limit policy during the election.
"The Mackays to Peka Peka and Peka Peka to Ōtaki Roads of National Significance, which make up the Kāpiti Expressway, were started by the previous National government and were designed and constructed to a high safety standard," he said in a media release.
"Since these roads opened, no one has died in a crash.
"In addition to the proven safety benefits of removing heavy traffic out of town centres like Paekākāriki, Paraparaumu, Waikanae, and Ōtaki, these RoNS have made regional freight trips more efficient.
"They’ve also enabled local road users to get to where they need to go more quickly and unlocked new opportunities for housing and urban development.
"I’m pleased to see NZTA is also making good progress on the next phase of this important corridor, from Ōtaki to north of Levin, and I look forward to seeing similar speed limits set once construction is completed in the coming years.”
