Following Cyclone Gabrielle, land in some areas remains unstable, particularly after rain. New landslides could occur and existing landslides could reactivate.
Properties next to, above or below those already affected by landslides could also be at an increased risk of further landslides.
In many areas, cliff top properties without extra stability measures, such as deep piled retaining walls, have experienced cliff collapse below them. These properties and nearby properties could suffer further damage.
If in doubt - get out.
If your house has a red ‘entry prohibited’ placard, you must stay out.
If your house has a yellow ‘restricted access’ placard, follow the directions on the placard and consider not entering the property during a severe weather event.
If your house is next to a property with a placard, or if you see any signs of instability, or if you are concerned about the stability of the land around your house, we recommend you are extra cautious during this likely severe weather event. Consider finding alternative accommodation during heavy rain.
Many landslides show some early warning signs in the minutes or hours before they occur. Common warning signs include:
If you feel it is unsafe to remain in your home or you have been ordered to evacuate, go to a designated evacuation centre or other safe place.
Stay away from a slip area. More slipping could occur.
If it’s safe, check for injured and trapped persons without entering the direct slip area. If you find an injured person, phone 111 and direct rescuers to their location.
