“Having to remain closed overnight is disappointing but necessary given the risk of more material coming down.
“Crews from both the northern and southern sides of the slip will be back at site tomorrow morning to re-assess the slip and continue work to clear it.
“Contractors are on-site and geotechnical evaluation is needed,” a Waka Kotahi alert read.
“The route can only be re-opened once it is safe to do so.”
It is the second time in a week the major road has been closed due to slips.
Last Sunday, November 26, a slip on SH2 just south of Wairoa resulted in a fatal crash about 4am that morning, when a car hit the slip in the dark.
The highway has been undergoing road works since Cyclone Gabrielle hit in February, which caused extensive damage to the road which connects Napier and Gisborne.
Waka Kotahi stated its Journey Planner had the closure information up around 5am on Sunday and the first social media posts were up just before 9am, letting people know of the closure.
