The Queenstown Lakes District Council said helicopter sluicing was used this morning to help shift the rock.
However, further assessment was needed to ensure the road linking Queenstown and Wanaka was safe before it could be reopened.
Meanwhile, NZTA said some main highways in the the South have been affected by slips and rock falls today.
Road users were advised to take care and to expect delays.
• State Highway 8 Cromwell to Alexandra: Due to emergency rock face stabilisation works near the intersection with Dairy Gully Rd, the highway will be closed for 10 minute intervals in both directions.
• Other parts along State Highway 8 have also been affected, including Lindis Pass to Raes Junction. Motorists should watch out for debris on the road from rock falls.
• State Highway 6 (Junction SH 8B) to Queenstown: Due to slip clearing works north of Waitiri, the highway will be down to one lane under stop/go traffic management with a 30km/h temporary speed restriction in place.
• State Highway 6 Haast to Kingston: Due to recent weather events, there is an increased risk of rock falls at various locations. Particular areas of caution are along the West Coast, Kawarau Gorge and the Devil's Staircase.
