Works would begin at midnight on January 19 and continue until midnight, January 23, withcontractors laying 42,000sq m of chipseal and applying a second seal on barrier areas and shoulders.
NZ Transport Agency (NZTA) would also carry out works at the intersection with Maungatautari Rd and general maintenance such as mowing and sign repairs.
NZTA Waikato Bay of Plenty regional manager of maintenance and operations Roger Brady said all traffic will take detours or alternative routes to avoid the area during the closure.
He said a closure was the most efficient and safest way to complete the work.
“To get maintenance and repair work done quickly, safely and cost-effectively, these full closures will become a regular event — up to three to four times a year.
“We appreciate this will have a major impact on people and we will give as much notice as possible of closures.
“[This] work is necessary to ensure the road is safe and accessible for everyone who travels on it.”
While all properties within the closure and side roads leading to it will have access maintained, delays are expected.
Vehicles will be grouped and piloted through the site.
Northbound traffic will be leaving on the hour from near the SH1/29 roundabout. Southbound traffic will be leaving on the half-hour from Karāpiro Rd, and people coming from side roads will join the convoy as it passes their road.

All visitors and service providers can join this piloted access when they are visiting a property within the closure.
Emergency services will have full access through the site at all times.
All other traffic will need to take detours or alternative routes to avoid the area.
The detours are via Karāpiro Rd/Taotaoroa Rd/SH29 in both directions, with a speed restriction of 70km/h.
State highway traffic and freight will be encouraged to use SH26/SH27. HPMVs and over-dimension loads also need to use SH26/SH27. This will add around 50 minutes to journeys.
Inter-regional traffic will be encouraged to use other routes, such as SH2/SH27 to the east of the closure. This will add around 18 minutes to journeys.
Traffic presenting at the stacking points at the north and south of the works area will not be turned around and can join the piloted convoys.
