A detour will be in place for much of the next two months on State Highway 3 between Turakina and Bulls near Dudding Lake.
Waka Kotahi NZ Transport Agency said the detour would be put in place for southbound traffic to allow resurfacing and drainage works to take place on the road.
Work will begin on Tuesday, October 24, and is expected to take seven weeks to complete.
During this time, the southbound lane will be closed from 6am to 6pm, Monday to Friday, and sometimes on a Saturday.
Southbound traffic will be detoured down Makirikiri Rd, onto Pukepapa Rd and back to State Highway 3.
