When crews switch to the other side of the road, southbound traffic will be detoured down Wakeman St, Sedcole St and Princess St and then back onto SH2.
These works will enable contractors to safely renew the line markings on the road.
The spokesman says Waka Kotahi acknowledges road closures can be disruptive and expect to be able to keep that disruption to a minimum by doing this work overnight.
“We want to thank road users in advance for taking the detours.”
