Environment Canterbury has a statutory responsibility, under the Building Act 2004, for issuing building consents for large dams and ensuring ongoing dam safety. The Building Act 2004 was passed by government to improve the control of, and encourage better practices in, building design and construction.
Environment Canterbury was accredited by International Accreditation New Zealand, and is now registered as a Building Consent Authority with the Department of Building and Housing.
This function means that Environment Canterbury is responsible for ensuring dams are well constructed, that dams are regularly monitored and that the potential risks to people and property are minimised. This function does not replace the requirement for resource consents for damming, taking or diverting water under the Resource Management Act 1991. Any applicable resource consents will still be needed before a dam project commences.
