Tasman District is in both a high and medium seismic risk area, according to the Building (Earthquake-prone Buildings) Amendment Act 2016.
The high seismic risk area is south of Wakefield and Tapawera and includes Murchison, St Arnaud, Belgrove, Motupiko and Kohatu.
The medium seismic risk area includes Wakefield, Tapawera and all points north.
The Council has set timeframes to identify buildings as either potentially earthquake-prone or not. Likewise, building owners have a set time to carry our seismic strengthening work.
The timeframes are set out in this table
|Seismic risk||Council must identify buildings by||Owner to complete seismic remediation within|
|Category||Priority buildings||Other buildings||Priority buildings||Other buildings|
|High risk||1 Jan 2020||1 July 2022||7.5 years||15 years|
|Medium risk||1 July 2022||1 July 2027||12.5 years||25 years|
If a building failure would have significant impact on public safety or critical transport routes, it may be considered a priority building.
For example, hospital, emergency services, civil defence, or education buildings may be critical to recovery in an emergency or natural disaster. Other earthquake-prone buildings may be priority buildings due to their location, and the potential impact of their failure in an earthquake on critical transport routes.
Priority buildings must be identified and remediated in half the time of other buildings.
We're at the early stages of this process, but over time we will write to affected building owners. Once buildings are identified they are added to the national register.
The register contains earthquake-prone buildings in Tasman District and throughout New Zealand.
Building owners will have 1 year, after being advised by us that their building is potentially earthquake-prone, to provide an engineering assessment. This period can be extended once, to a maximum of 12 months (maximum).
You'll need to write to us so we can consider an extension. The process is subject to strict criteria.
The definition of seismic work includes both strengthening of a building, or demolition.
Funding is available to support earthquake strengthening of earthquake-prone heritage buildings.
The Ministry for Culture & Heritage Manatu Taonga has a Heritage EQUIP fund, to support earthquake strengthening of earthquake prone heritage buildings.
The Building (Earthquake-prone Buildings) Amendment Act 2016 came into effect on 1 July 2017, amending the Building Act 2004 (“Act”). This overrides and replaces the earthquake-prone provisions of Councils’ former Earthquake-prone, Dangerous and Insanitary 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(external link).
The council adopted this policy in March 2019
