Natural hazard risks

Find out how natural hazards may affect your building consent.

Natural hazards include:

  • erosion (including costal erosion, bank erosion, and sheet erosion)
  • falling debris (including soil, rock, snow, and ice)
  • subsidence
  • inundation (including flooding, overflow, storm surge, tidal effects, and ponding)
  • slippage

Take a look at our Natural Hazards and the Building Act 2004 information sheet (529 kb) for more information.

Section 72 offers a solution by allowing (in certain situations) an owner to take on the risk of building on hazardous land. It requires that a warning is placed on the legal title.  This warns future property owners of the potential hazard, and reduces Council and EQC's liability if the land is damaged because of the hazard.

If Council considers that the land is subject to a hazard, we must:

Before we do this, we will ask the owner to acknowledge (in writing) that they understand the implications of this, and provide an opportunity for further discussion.

If you think natural hazards may apply to your project, we recommend:

  • getting professional or legal advice so you can make fully informed decisions.
  • booking a pre-application meeting with us to help you understand the possible hazards on your site.
