The 50m-wide slip at 7pm on Sunday has closed both lanes of Kopu-Hikuai Rd, police say.
It has occurred near Kitahi Rd, close to the summit.
Diversions are being put in place at the intersection with SH25 in Kopu, and at the Whangamata/Tairua intersection with SH25.
It could take until Monday morning to clear the slip and traffic control will remain in place.
