Proposed regulations for dam safety

Days left

Submissions due: 06 August 2019, 5pm

We are seeking your comment on proposed safety regulations for large dams.

These regulations propose to establish a nationally consistent approach that will protect people, property and the environment from the potential impact of a large dam’s failure without imposing undue compliance costs.

This will bring New Zealand into line with the majority of OECD countries that already have dam safety schemes in place.


The proposed new scheme pulls together post-construction regulatory requirements into a single, consistent nationwide framework. The owners of dams will be responsible for ensuring that their dams are being managed appropriately, proportionate to the risk they pose.

The proposals aim to ensure that classifiable dams are well maintained and regularly monitored, and that potential risks of dam failure are reduced.

The scheme also recognises that the dam safety requirements need to be regularly reviewed because the consequences of dam failure can change over time due to factors such as site conditions, urban development or population growth.
