A Certificate of Compliance electrical work NZ homeowners receive after a job is completed is more than a piece of paper. It is a legal document confirming that the electrician carried out your electrical work safely, correctly, and in accordance with New Zealand’s electrical safety regulations.
If you have recently had electrical work done and are wondering what this certificate means, why it matters, and what to do with it, this guide covers everything you need to know.
What Is a Certificate of Compliance in NZ Electrical Work?
A Certificate of Compliance, often called a CoC, is a formal document the licensed electrician who completed your work must issue. It confirms the work meets the requirements of the Electricity (Safety) Regulations 2010 and the NZ Wiring Rules (AS/NZS 3000).
The CoC covers what is known as prescribed electrical work. This includes most fixed wiring tasks: installing new circuits, adding power points, upgrading switchboards, and connecting hardwired appliances. It does not apply to minor maintenance tasks such as replacing a light fitting or a socket.
Your electrician must provide the CoC within five working days of completing the job. They must also keep a copy for their own records.
Keep your copy somewhere safe. You may need it if you sell your home, make an insurance claim, or have further electrical work carried out in the future.
Why Does Certificate of Compliance Electrical Work NZ Documentation Matter for Homeowners?
There are three practical reasons this document matters to you as a homeowner or property owner.
Insurance. Most home insurance policies require a licensed professional to carry out electrical work. If something goes wrong and you cannot produce a CoC, your insurer may decline the claim. Having the certificate on file protects your position.
Property sales. When you sell your home, buyers and their solicitors often request CoCs for any electrical work carried out on the property. Missing documentation can delay a sale or reduce buyer confidence.
Safety verification. The CoC confirms your electrician tested the work before signing off. It is independent proof that your wiring is safe and compliant, not just their word for it.
A Note for Landlords
Landlords also need to pay attention here. CoC records form part of your broader compliance responsibilities under the Healthy Homes Standards and the Residential Tenancies Act. Keeping these on file helps you demonstrate that your rental property meets its legal obligations.
What Should a CoC Include?
A valid Certificate of Compliance for electrical work in NZ must include specific information. Look for the name and registration number of the electrician, a description of the work, the address where it took place, the date of completion, and a declaration confirming compliance with the relevant regulations.
If your CoC is missing any of these details, contact your electrician and ask for a corrected version.
What If My Electrician Did Not Provide a CoC?
If your electrician completed prescribed electrical work and did not provide a CoC, follow it up. NZ law requires them to issue one. Failing to do so can result in fines of up to $10,000 for the electrician and leaves your property without proper documentation.
If the work was recent, contact the electrician directly and request the certificate. If you cannot reach them, or the work took place some time ago, a licensed electrical inspector can assess the installation and advise on the right path forward.
Working with a registered, licensed local electrician from the start avoids this situation entirely.
Common Questions About Certificate of Compliance Electrical Work NZ
Do I get a CoC for every electrical job? Not for every job. CoCs cover prescribed electrical work, which includes most fixed wiring tasks. Electricians do not issue them for minor maintenance work such as replacing a socket or a light fitting.
How long should I keep my CoC? Indefinitely. A CoC has no expiry date, and you may need it years later for an insurance claim, a property sale, or when planning future electrical work.
Can any electrician issue a CoC? No. Only licensed electricians registered with the Electrical Workers Registration Board (EWRB) can issue a Certificate of Compliance in New Zealand. You can verify your electrician’s registration through the EWRB online register.
What is the difference between a CoC and a Certificate of Verification? The electrician who did the work issues the CoC. A licensed electrical inspector issues a Certificate of Verification after independently checking the work. Some high-risk jobs, such as work on a main switchboard, require both.
What happens if electrical work has no CoC? Work without the correct certification may not meet NZ safety standards. It can affect your insurance cover, create issues when selling your property, and may present a safety risk. If you are unsure whether previous work has proper certification, a licensed electrician can assess the installation.
