Port Hills land damage

The Port Hills suffered significant land damage as a result of the 2010/2011 Canterbury earthquakes.

Assessments of the level of damage and decisions around the future of the land are ongoing. Several hundred homes remain at risk of rockfall, cliff collapse or other geotechnical issues. Notices have been issued under the Building Act prohibiting entry because of the danger.

Determining retaining wall responsibilities

Information on determining retaining wall responsibility - Feb 2014

Christchurch City Council is contacting property owners around the Port Hills and Lyttelton area, with assistance in determining responsibility for retaining walls adjacent to Council assets.

Following the earthquakes the Council, along with Stronger Christchurch Infrastructure Rebuild Team (SCIRT), has worked on retaining walls which posed a danger to public safety or blocked public access routes. The next step we are taking is to determine who is responsible for less-critical retaining walls. This will give clarity to residents about the responsibility for repairing them and what will happen next.

In cases where the Council is responsible for retaining walls, SCIRT will be responsible for their reconstruction and will inform households in the area well in advance of any construction work.

In cases where home owners are responsible for a retaining wall, they will need to work with the Earthquake Commission and to contact their insurer to check whether their insurance policy covers retaining walls.

To assist with this process we have produced a booklet detailing common scenarios: Determining responsibility for retaining walls [PDF 800KB].

If you require further information or assistance, please contact the Christchurch City Council Call Centre on (03) 941 8999 or 0800 800 169 .
