What they do

NZSOLD aims to protect people, property and the environment, present and future, from the harmful effects of a dam failure or an uncontrolled release of the reservoir contents.

It develops and provides information to members and represents the industry at government level. It actively reviews and shares information on an international stage to best represent dam practice in New Zealand.
