Slopes and retaining walls
Slopes and retaining walls can crack, move or even collapse, particularly if they’re affected by pressure from heavy rainfall, earthquakes or other natural disasters.
Types of retaining walls
You'll find information about different types of retaining walls on BRANZ's Build Magazine website.
Retaining wall regulations
Smaller retaining walls may not need consent but must meet Building Code requirements, as explained on MBIE's building website.
Talk to your council
Ask your council for information about existing or new retaining walls. You can find their contact details on the Local Councils website.
