Electrical Consent in NZ: What You Need and When
There is no single thing called an “electrical consent” for a typical home job in New Zealand. Depending on what you are doing, you are dealing with one of three things: a building consent from your council, the electrical certificates your electrician must issue (Certificate of Compliance and Electrical Safety Certificate), or a close approach consent from your local lines company if work happens near overhead power lines. This guide explains which applies to your project and what to ask for.
TL;DR
Most fixed-wiring work must be done by a licensed electrician, who issues a Certificate of Compliance (CoC) when the work is finished and tested.
A building consent is a separate council process. Electrical work is not automatically consented, but it becomes part of the paperwork when your wider project (a new bathroom, for example) needs a consent.
Close approach consent comes from your local lines company, not your council, and applies to work near overhead lines.
Homeowners can do only a limited amount of their own electrical work, and it must be tested and certified by someone qualified.
Keep every certificate. Insurers and buyers ask for them.
Table of Contents
Three different approvals people call “electrical consent”
The search term covers several processes run by different bodies. Mixing them up is the most common source of delays.
What it is | Who issues it | When it applies |
Building consent | Your local council | Building work that is not exempt, including some projects with electrical elements |
Certificate of Compliance and Electrical Safety Certificate | The licensed electrician | Prescribed electrical work done by a professional |
Close approach consent | Your local lines company | Work or machinery near overhead power lines |
A council consent does not replace the other two. Lines companies are clear that having a building or resource consent does not give you approval to work near power lines.
Electrical certificates: what your electrician must give you
For most work done by a professional, the paperwork is the electrician’s job, but it is your record, so you should know what to expect.
Certificate of Compliance (CoC)
WorkSafe says electricians must give customers a CoC when doing any fixed wiring work, including fitting new power points. The CoC shows the work was tested and carried out to New Zealand’s electrical safety standards. If you searched for “certificate of compliance electrical NZ”, this is the document you want.
WorkSafe also advises keeping it somewhere safe, because it may be needed for insurance claims or when you sell.
Electrical Safety Certificate (ESC)
Once the installation is connected to the supply, the electrician issues an ESC. The WorkSafe guidance sets this at typically within 20 working days of connection. If you do not receive it, ask for it in writing.
Record of Inspection (RoI)
Higher-risk work, such as work on main switchboards or cables, also needs a Record of Inspection from a licensed electrical inspector, per the same WorkSafe page. Ask your electrician at quote stage whether your job falls into this category, because it adds an inspection step to your timeline.
Energy work certificate for building consent projects
If your project has a building consent, Building Performance explains that owners should receive an energy work certificate from any electrical worker or gasfitter on the property, certifying the work is safe, legal and complete. These certificates need to go in with your application for sign-off.
When electrical work sits inside a building consent
Electrical work on its own is regulated mainly through the licensing and certification system above. Building consent enters the picture when the project around the wiring needs one.
The usual example is a bathroom. Building Performance notes that new wet areas and added sanitary fixtures involve waterproofing and other requirements that trigger a building consent. The electricians’ certificates then become part of the file the council reviews at the end.
The end of the process is the Code Compliance Certificate (CCC). Building Performance advises applying to council for sign-off as soon as you believe the work is complete. If your contractors have met all consent requirements, including scheduled inspections, getting a CCC should be straightforward. Missing electrical certificates are an easy way to stall it.
For more on what does and does not need a council consent, see our guide to building consent exemptions in NZ. If you are adding a bathroom, our article on drainage and consent for a second bathroom covers the costs people miss.
Typical jobs and what they involve
This table is a planning aid, not a ruling. Your council and electrician confirm the detail for your property.
Job | Electrician and certificates | Building consent |
Adding power points or lights | Licensed electrician, CoC and ESC | Check with your council |
New bathroom or wet area | Licensed electrician, certificates go to the CCC file | Required for new wet areas and added fixtures |
Kitchen renovation with new circuits | Licensed electrician, CoC and ESC | Depends on the other building work |
Work near overhead lines | Electrician as above | Separate close approach consent from the lines company |
Can you do your own electrical work?
Partly. WorkSafe states the law allows a member of the public to carry out some of their own electrical work, but it does not recommend this unless you have the skills and knowledge. The limits are tight:
The exemption applies to your own private residence. It does not cover rentals, or a family member’s home where you do not live.
The work must be done without payment or reward and follow NZECP 51:2004.
You must not enter enclosures where live conductors are present or do any work on switchboards.
The work must be tested, certified and connected to supply by a licensed electrical inspector.
The detail is set out in regulation 57 of the Electricity (Safety) Regulations 2010. The Electrical Workers Registration Board also reminds readers that registered non-licensed persons may not carry out prescribed electrical work for others, whether paid or not.
In practice, once you factor in testing and an inspector, a licensed electrician is usually the simpler route. If you hire a handyman for “a quick power point”, check first that they are a licensed electrician and will issue a CoC.
Close approach consent: working near power lines
This is the consent most closely tied to the phrase “consent” in the electrical world, and it catches homeowners off guard on sites with overhead lines, such as a digger for a new driveway, a crane lift, or scaffolding.
The New Zealand Electrical Code of Practice for Electrical Safe Distances (NZECP 34) sets minimum distances. Vector explains that use of mobile plant within 4 metres of power lines is restricted, and if you cannot stay clear you need a close approach consent. The code itself also covers building or excavation near line support structures such as poles and stay wires.
A few practical points:
Apply to your local lines company before work starts, not after the contractor arrives.
These consents can have short validity periods and specific conditions that the on-site supervisor must understand, according to MainPower.
Tell every contractor on site about the lines. The person doing the work carries the legal obligation, so it needs to be on the job plan.
Which lines company applies depends on your address. Your power bill or council can tell you.
Why the paperwork matters later
Certificates are legal and practical records. If you sell, buyers and insurers often ask for them. WorkSafe’s advice to buyers is to ask the vendor about all electrical work and sight all CoCs. Missing records can slow a sale or leave you exposed if something goes wrong.
Storing them well is part of the job. Some builders now collect signatures and completion records digitally, and there is a useful walkthrough on signing off practical completion electronically if you want a tidy audit trail of what was signed and when. Whatever method you use, store the CoC, ESC, energy work certificate and CCC together.
If you already have electrical or building work done without paperwork, see our guide to legalising unconsented work in NZ. For the insurance angle, read what to check before you hire a renovator.
Our view on electrical paperwork in renovations
We manage kitchens, bathrooms and full renovations in Auckland, and electrical certification is one of the items that gets lost most easily when several trades work in sequence. The electrician finishes, the plasterer and painter follow, and weeks later nobody can say who holds the CoC.
Our approach is simple. One point of contact tracks the certificates the same way we track everything else on the job. Licensed trades are coordinated through us, so you are not chasing an electrician, a plumber and a council officer separately. Where a project needs a building consent, we manage that process as part of the job.
Our advice to any homeowner, whoever you hire:
Ask at quote stage which certificates you will receive and when.
Do not make the final payment until the CoC is in your hands.
Keep digital copies of everything in one folder.
If your site has overhead lines, raise it before the first day of work.

Getting the whole renovation sorted
If your electrical work is part of a larger project, it is easier to have one team manage the trades, the consent and the certificates. We offer fixed-fee renovation packages for kitchens and bathrooms, as well as full home renovations. For smaller jobs such as vanity and fixture swaps, see our small jobs services.
FAQ
Do I need building consent to add a power point in NZ?
The electrical side is controlled by licensing and certification: a licensed electrician fits it and issues a CoC. Whether the building consent applies depends on the surrounding building work, so check with your council if the job involves more than the wiring. Your electrician can usually tell you quickly.
What is a Certificate of Compliance for electrical work?
It is the document an electrician gives you after fixed wiring work, confirming the work was tested and meets New Zealand’s safety standards. WorkSafe says to keep it as a record, since insurers and buyers may ask for it.
Can I do my own electrical work in NZ?
Only a limited amount, on your own private home, without payment, and following the code. The work must be tested and certified by someone qualified, and you cannot work on switchboards or enter enclosures with live conductors. WorkSafe recommends using an electrician unless you have the skills.
Can I put a shower and toilet in my garage in NZ?
Adding a shower or toilet creates a new wet area with added sanitary fixtures, which Building Performance says triggers a building consent. Any electrical work in it also needs a licensed electrician and certificates. Speak to your council before starting.
Does a building consent cover work near power lines?
No. You may still need a close approach consent from your local lines company if work or machinery comes within the restricted distances of overhead lines.
