On Monday and Tuesday, there will be a right lane closure around the Maunganui/Girven Rd roundabout as well as on all four approaches to the roundabout.
There will be a temporary speed limit of 30km/h in place around the Bayfair roundabout for the duration of these works.
Road users are advised to travel with caution through the project site, drive to the conditions, reduce speed and follow the directions of road workers and signage.
The agency said this work may generate some noise and vibration.
Work will be delayed to the next suitable nights if there is unsuitable weather or other unforeseen circumstances.
