New Zealand Recovery Underway - continued
Four minor slips near Irongate have already been cleared. The material from these being used to build construction access track to other areas or stockpiled for future use.
There is already a large fleet of heavy machinery – excavators and bulldozers with more arriving all the time as access to more remote areas is made possible.
Helicopters sluicing and rock removal has been used on various slips where there is evidence of substantial loose material.
Nine helicopters are dropping more than one million litres of water on the slips to the north of Kaikoura each day to wash off the loose rock and debris and make these safe for crews to move on-site with machinery to begin removal.
They have used more than 63 million litres of sea water to date and are making good progress. This work continued for a few weeks.
Crews continue the dangerous scaling work, making these areas stable for remote controlled excavators to make their way through to Ohau Point.
The use of remote controlled excavators allows clearance work to proceed more quickly. The risk to site personnel is minimized as they are operating the excavators at a distance from the danger areas.
These slips remain highly unstable and hazardous, with large rocks and other loose material frequently falling.
