A geotechnical report will be required for a resource consent:
- for any excavation, construction, alteration or modification to any structure, building or retaining wall in the Land Stability Assessment Areas (LSAA). You can find out if your property is in the LSAA – visit our online maps and searching for your property address.
- if a consent notice registered against your certificate of title says you require one.
In most instances, a geotechnical report has to be written or reviewed by a suitably qualified and experienced practitioner. For a list of the Council's suitably qualified and experienced geotechnical engineers please see our list of Geotechnical practitioners(PDF, 36KB).
Note: If your property is located in the LSAA and you require a geotechnical engineering report, a suitably qualified and experienced geotechnical engineer is one who has 'geotechnical' listed as one of their practice field on the Engineering NZ register. You can check if your geotechnical engineer meets this requirement by searching for them on the Registration Authority website.
Contact the Duty Planner for confirmation if you are unsure whether you require a geotechnical report for your proposal.
