Major Hazard Facilities and Regulations

In 2015 a new Health and Safety at Work Act was introduced, which included specific regulations for Major Hazard Facilities (MHFs). If a facility has certain hazardous substances present in quantities above a set threshold, then it is classed as a MHF under the MHF Regulations. The Regulations are overseen by a specialist group within WorkSafe New Zealand and are designed to provide oversight and safety assurance of MHFs.

We operate two geothermal power stations which are classified as MHFs. MHF facilities may be either an upper tier or lower tier facility depending on the quantity of specified hazardous substances onsite.
