Earthquake Prone Building Information

New Zealand has a relatively high earthquake risk so it is important for safety reasons that buildings are built or upgraded to be safe in an earthquake.


Consultation has closed for submissions on Nelson’s proposed approach to Priority Earthquake Prone Buildings. Deliberations on submissions received will be considered at an ordinary Environment Committee meeting early in 2020.  Priority buildings have shorter timeframes for identification and remediation. The outcome will establish which streets and areas we will look at improving first.

List of Earthquake Prone Buildings

Earthquake-prone buildings in Nelson and throughout New Zealand can be viewed on the Ministry of Business, Innovation and Employment’s EPB Register website.


The Building (Earthquake-prone Buildings) Amendment Act 2016 came into effect on 1 July 2017, amending the Building Act 2004. This overrides and replaces the earthquake-prone provisions of Councils Earthquake Prone Building Policy 2006.

An overview and detail of the new regime is available on the Ministry of Business, Innovation and Employment’s Building Performance website.

In terms of the Act, Nelson City is a medium seismic risk area.
Nelson City Council (NCC) has set timeframes to identify buildings that meet certain characteristics, known as profile categories, as either potentially earthquake-prone or not. The timeframes are:

  • 5 years (expiring 30 June 2022) to identify priority buildings and parts of buildings that are potentially earthquake prone.
  • 10 years (expiring 30 June 2027) to identify other buildings and parts of buildings that are potentially earthquake prone.

Building owners will have 1 year, extendable on application to 2 years, after being advised by NCC that their building is potentially earthquake-prone, to provide an engineering assessment.

If an earthquake-prone building (EPB) Notice is issued:

  • Owners of priority buildings will have 12.5 years from the date of the Notice to complete seismic work.  
  • Owners of other buildings will have 25 years to complete seismic work.
  • Old Notices, issued prior to 1 July 2017, will be reissued with deadline dates based on the original Notice, but limited to the above maximum timeframes.  If the old timeframe is less than those above, then owners can apply to have the timeframe extended.
  • Owners of earthquake prone buildings can apply for an exemption from the requirement to carry out seismic work.
  • Owners of certain heritage buildings can apply for an extension of time to complete seismic work.

Worksafe New Zealand Position Statement

Worksafe New Zealand have issued a position statement dealing with earthquake-related hazards that is directed at employers, owners of workplace buildings and their advisers (such as engineers).

Heritage EQUIP Fund

Funding is available to support earthquake strengthening of earthquake-prone heritage buildings. For more information see our Earthquake Prone Heritage Buildings page.
