More than 9,700 residential properties in the Christchurch Port Hills area have been rezoned from white to green. About 3,700 properties remain in the white zone as further investigation is needed.  The issues in the Port Hills are different to those in the low lying plains areas where there has generally been widespread land damage from liquefaction and lateral spreading.

In the Port Hills, the issues have largely involved potential rock fall, cliff collapse and land slips.Extensive geotechnical assessment supported the decision to rezone most of the Port Hills to green as it had shown a low geotechnical hazard risk.  More Port Hills land will be rezoned green soon, once further investigation and assessment is completed.
