Public consultation has begun on whether speed limits on State Highway 1 at Transmission Gully and the Raumati Straights should increase to 110km/h.
Transport Minister Chris Bishop is encouraging people to have their say on the proposal.
“With around 22,000 vehicles using the road daily, it provides important regional resilience and a safe, modern, reliable route for all road users,” Bishop said.
Bishop said that the road was designed and constructed to a high safety standard, which is reflected in the low crash numbers since its opening in 2022.
Since opening, there have been 150 strikes into the flexible median barrier between opposing lanes, but no deaths.
NZ Transport Agency will also be consulting on Raumati Straights, which connects Transmission Gully with the Kapiti Expressway, which is already 110km/h.

“By consulting on this section now, we can finalise a decision on appropriate speed limits quicker, ahead of possible safety improvements on the section,” Bishop said.
“This is all part of the Coalition Government’s agenda to deliver the infrastructure needed to grow the economy, reduce travel times and increase the productivity of our transport network.”
Recently, a 5.5km section of SH1 north of Auckland had its speed limit raised to 110km/h between the Northern Gateway Toll Road, from north of Orewa to south of the Johnstone’s Hill Tunnel.
Consultation begins on Friday, May 30 and will last six weeks.
