CCTV & the Privacy Act NZ — the Auckland installer's plain-English guide
CFU has installed 350+ Auckland camera systems since 2018. This is what we tell every client before we quote. Not legal advice — real installer's read on the NZ Privacy Act, Crimes Act audio rules, boundary aim, footage retention and signage.
Important: We install cameras for a living, we're not lawyers. This is what we've learned across 350+ NZ installs and what the Privacy Commissioner's own guidance says. For a specific legal issue, call the Office of the Privacy Commissioner (0800 803 909) or a lawyer.
The 5 questions we get on every install
Is it legal to have security cameras at home in NZ?
Yes. On your own property, filming your own home, driveway and yard is legal. The care point is aim: point cameras away from neighbours' windows, their private areas and public spaces beyond your boundary. The Privacy Act applies once you capture other people's footage, so treat what you record responsibly.
Can my security camera record audio in NZ?
Be careful here. Under the Crimes Act 1961 it is generally unlawful to record private conversations you are not part of, which is why most cameras sold in NZ ship with audio off. Our standard advice for home systems: leave audio recording off unless you have taken specific advice.
Can my neighbour point a camera at my property?
They can film their own property, and incidental capture of the boundary is usually fine. A camera deliberately aimed into your windows or private outdoor areas may breach the Privacy Act. Best first step is a conversation over the fence; after that, the Privacy Commissioner handles complaints.
How long can I keep CCTV footage in NZ?
Only as long as you need it. The common practice is around 14 days for homes and around 31 days for commercial sites, with older footage overwritten automatically. Holding footage indefinitely without a reason can put you on the wrong side of the Privacy Act. A correctly sized NVR does the deleting for you.
Do I need a sign if I have CCTV at my business?
Under the Privacy Act you must tell people they are being filmed at a business, and clear signage is the standard way to do it. It also does double duty: the sign itself is part of the deterrent. We can point you to compliant signage as part of a commercial install.
How CFU handles this on every install
Four things we do on every job so the legal side stays clean without you having to think about it.
Aim
We walk the property with you and angle every camera 15° in from the boundary line. If a camera has any chance of capturing a neighbour's window or public footpath, we adjust it on the spot.
Audio
Every camera we install ships with audio recording off by default on residential jobs. If you specifically want audio enabled we ask you to sign off on the Crimes Act 1961 note first.
Signage
Every commercial install includes compliant Privacy Act signage — supplied and mounted at the entry points. Kills the "I didn't know I was being filmed" complaint before it happens.
Retention
We size your NVR drive to 14 days residential or 31 days commercial by default, so old footage overwrites automatically. No indefinite storage, no manual delete, no Privacy Act headache.
