The NZ Transport Agency (NZTA) says that the Rimutaka Hill Road is closed in both directions because of a slip.
Contractors are now on site and estimate that about 50-60 tonnes of material fell from the hill, completely blocking one lane and partially blocking the other.
It’s expected that one lane will be open to traffic later this afternoon on a Stop/Go basis, with both lanes open late this afternoon or in the early evening according to the NZTA.
Motorists are advised to delay travel or use an alternative route.
The slip occurred about one kilometre north of Kaitoke, on the Upper Hutt side of the hill.
