Work to reseal State Highway 2, between Moffat Rd and Parau Drive in Bethlehem, will start this weekend.
The roadworks will be completed overnight from May 2 to May 7, between 6pm and 6am.
One northbound lane will be closed to traffic, the other northbound lane will remain open and a 30km/h temporary speed limit will be in place, Waka Kotahi NZ Transport Agency says.
During the day all lanes will be open as usual and no work is planned for the southbound lanes.
