One of the main routes between Central Wellington and the western suburbs will be closed for the rest of the weekend and possibly early next week following landslips this morning.
Two landslips occuring next to each other have thrown debris and large boulders onto sections of Ngaio Gorge Road.
Contractors who were removing the rubble this morning have been pulled back because of further falling debris.
Consultant engineers, Wellington City Council and Police say they won't open the road again until it's safe.
The Council says: "At the moment the engineers are working out how they'll remove the large amount of material that's still above the road, it might involve a helicopter and monsoon bucket but that decision has yet to be made."
Nearby Old Porirua Road is only in use in the downhill direction.
Drivers are being advised to use other alternative routes like the Ngauranga Gorge, Onslow road and Churchill drive via Wadestown.
