Delays are expected on State Highway 2 near Matatā, as roading crews complete chipsealing works.

From 7am on Thursday, crews are expected to start setting up on the highway, near Mimiha Rd, and plan to be finished by 6pm, said a statement from NZ Transport Agency Waka Kotahi.

While this work is under way, stop/go traffic management and a reduced speed limit will be in place.

NZTA warned this will be disruptive and may cause delays of up to 30 minutes.

“NZTA would like to apologise for the lengthy delays experienced when earlier resealing works at this location were completed.

“The programme has been reviewed to ensure delays will be minimised for this final section of reseal works.”

Once crews finish laying the fresh chipseal, a reduced speed limit of 30km/h will be in place.

NZTA said that speed helps the stone chips compact and interlock properly, which is key to creating a strong, long-lasting surface.

“Please stick to the reduced speed limit, if you go too fast, you’ll flick loose chips off the road, leaving gaps behind. If you go too slow, the surface can overheat and stick to your tyres, pulling up chips and damaging the seal.

“We appreciate your patience and understanding while these essential works are carried out.”

In the event of bad weather or unforeseen circumstances, NZTA said the work may be postponed.
