New Zealand’s removal of a ban on modifying electrical earthing systems is under review due to safety risks, including potential electrocution.
A New Zealand rule change allowing switches or fuses in mains earthing systems is under review after electrical inspectors warned it could make safe installations lethal by risking electrocution.
The change, which removed a ban on modifying the protective earth neutral (PEN) conductor, aims to support electric vehicle charging and disaster resilience.
Inspectors call the move "very dangerous," saying it could raise earth connections to dangerous voltages even without faults.
WorkSafe commissioned an international review, issued initial guidance, and is developing further technical advice, while the government continues evaluating the findings amid ongoing safety concerns.
