To keep Karangahake Gorge gorgeous, the section of State Highway 2 will close for five nights.
New Zealand Transport Agency Waka Kotahi has confirmed there would be overnight closures and traffic reduced to a single lane on SH2 through the gorge from April 7, to allow for road resurfacing.
The road would close from 8pm to 5am each night and temporary speed limits would be in place during the day.
Detours would be via SH27, SH24 and SH29 and via SH25 and SH25A.
Motorists taking the SH29 detour were asked to note that there would be night-time stop/go works on SH29 over the Kaimai Range for resurfacing at the same time, so they should expect delays, NZTA said in an advisory notice.
