As flood-weary Aucklanders continue their clean-up from this week's heavy rain, many are dealing with slips that are affecting their property.

Hills and cliffs around any number of suburbs in the city have been subject to landslides, with homes around them given red or yellow stickers.

But what makes a property vulnerable to slips? 

Are there any warning signs one is imminent, and if so is there anything you can do? One of those who has been out assessing slips around Auckland over the past few days is Paul Fletcher, an associate at geotechnical engineering firm ENGEO.
