Electrical and wiring regulation U-turn welcomed

Last year, in an effort to reduce barriers to the installation of renewable energy technologies including solar panels and EV chargers, the Government made a number of regulatory modifications, including removal of rules that prohibit the switching of protective earth and neutral (PEN) conductors.

Electrical safety experts from across the sector warned this would have put Aotearoa in stark contrast to international standards and minimum practice – putting electricians, inspectors and all users of modern electrical installations at risk of electrocution.

Engineering New Zealand strongly advocated against the law change, raising concerns directly with MBIE, Worksafe and the Minister for Energy, Hon Simeon Brown. MBIE has today confirmed the decision to reverse the PEN conductor regulatory change.

“This is an excellent outcome for public and industry safety. It should also give confidence to both wider industry and the public that expert advice has been listened to, considered and acted upon,” said Dr Richard Templer, Chief Executive of Engineering New Zealand.

“Ultimately this outcome demonstrates the importance of engaging closely with engineers and industry experts when regulatory changes are considered.”

“A lot of credit must go to the tireless work of some of our members, particularly in the Electrical Engineering Group, as well as wider organisations including the New Zealand Electrical Inspectors Association, Solar Association and Master Electricians, who have consistently pushed for this change for the safety of their own members, colleagues, wider industry and the public.

Engineering New Zealand thanks all those involved in the process, including the Minister and MBIE officials, for helping ensure New Zealand's electrical safety standards remain aligned with international good practice.
