The speed limit on State Highway 1 through Kaiwaka is to be reduced from 100km/h to 60km/h in an effort to increase safety for residents and road users.
The New Zealand Transport Agency said it was introducing more consistent speed limits, which means there will be lower limits over a greater stretch of the highway.
"By introducing just one speed limit that is clearly signposted and doesn't change partway through the township, it's anticipated that motorists will understand what's expected of them and are more likely to drive within the limits," agency system design manager Brett Gliddon said.
The new 60km/h speed limit will be introduced this month from 285m northwest of Kaiwaka/Mangawhai Rd to 300m south of Settlement Rd.
The stretch of road through the township is now variously 100km/h, 70km/h and 50km/h.
Gliddon said other improvements planned in the next few months are large signs and road markings on the road and roadsides at both ends of the town.
"Along with an electronic display this will help clearly signal and reinforce the drop in speed from 100km/h to 60km. Further signs will be installed every 500m to reinforce the reduced speed limit," Gliddon said.
A pedestrian refuge is also being built near the Italian Bakery to improve safety for pedestrians.
"We know that reducing speeds and improving safety is a top priority for the Kaiwaka community and the Transport Agency believes these changes will encourage motorists to drop their speeds," he said.
"This will create a better balance in helping freight and commuter vehicles travel safely and efficiently through Kaiwaka without compromising the safety and amenity of local residents.
"Encouraging safer speeds and reducing deaths and serious injuries on our roads is a top priority for the Transport Agency and in many cases the consequences of a crash can be significantly reduced, or even completely avoided, if drivers reduce their speeds."
