The speed along a section of State Highway 2 near Tauranga will be lowered from 100km/h to 50km/h for the next two weeks.
The NZ Transport Agency said in a written statement that the stretch between Apata and Omokoroa would have a lowered speed temporarily, starting today and lasting until May 10.
The restriction will be between Esdaile Rd and Youngson Rd between 9am and 4pm.
NZTA Bay of Plenty system manager Rob Campbell said safety was a priority and the agency was lowering the speed to ensure the safety of contractors.
"During this time our contractors will be measuring the location, shape of the road and taking note of size and position of all signs, street lights, and trees to help build a 3D map of the current road for design and construction drawings."
