Once work is complete, you might be issued certificates to prove it was done legally and safely. You'll also need to update your insurance cover.
Certificates prove work has been:
- carried out by an authorised person
- it complies with NZ laws and safety requirements.
These are legal documents and so you should keep them — you might need them when you come to sell your house.
Code compliance certificates
If your building work required council consent, you'll get a Code Compliance Certificate when the job is finished and the Council is satisfied the building and plumbing work complies with the Building Code and the consent.
Discuss with your contractor whether they'll apply for the code compliance certificate or if you need to do it yourself.
Your local council's website might have more information about their process.
All electrical work must be tested and certified, whether it’s a repair, replacement or new wiring. When work is finished, you must be given a copy of the certification.
The type of certification will depend on the work that was done. It could be all or a combination of:
- a Certificate of Compliance (COC)
- an Electrical Safety Certificate (ESC)
- a Record of Inspection — for work that needs to be independently inspected (ROI)
- a safety tag for any repaired appliances.
Energy works certificate
When gasfitting work is done, you must be given a signed copy of the gasfitting certificate (also called an energy works certificate).

If you didn't have a written quote or contract
If you didn’t have a quote or contract, you can ask for an itemised account or invoice for work that has been done. Service providers don't legally have to provide an itemised invoice but most will if asked.
If the work you've had done will increase the value or rebuild cost of your home, make sure you speak to your insurance company about increasing your cover.
