Welcome to your source of information about landslides in New Zealand.  This site summarises all you need to know in order to be prepared for a landslide, and what to do if one occurs.

The study and remediation of landslides are part of the discipline of engineering geology. If you need professional advice it is recommended that you contact a registered Professional Engineering Geologist or a Chartered Engineer specialising in geotechnical engineering. You can find out more about engineering geology and geotechnical engineering here.

Report a landslide

In the event of an imminent or actual landslip where lives are in danger or a road is blocked, evacuate, warn your neighbours, then dial 111. You may see signs of a landslide in advance. These can include:

• Unusual sounds such as trees cracking, rumbling or rocks falling or knocking together
• A faint rumbling sound that increases in volume is noticeable as the landslide nears
• Cracks in the ground or buildings growing in size

There are many other longer-term signs. Find out more on the advice for homeowners page.

If in doubt, get out.

Do not try to cross the slip debris as it often contains voids, dangerous materials and other hazards. Trying to stop or dig out the landslide can quickly make it worse, so get expert advice before trying to intervene.

You will then need report the details of the slip to the relevant bodies. These are: 

• For landslides on private land, the landowner (or if you are the landowner, your insurance company)
• For landslides that might affect roads, railways or public land, contact your local authority. You will also need to manually inform the relevant landowners, road operators or local authority, as not all will actively monitor the slip reporting tool. You can find the contact number for your local council here.

You can make things easier for the report by also submitting it on the form below, but it is important that you also make the phone call as this online form does not result in an immediate response:
