CCTV and the NZ Privacy Act: what businesses need to know

CCTV footage of people is personal information, so the Privacy Act 2020 applies. Here is what the Office of the Privacy Commissioner expects, translated into practical steps for an Auckland business.

By the Com4 team, Penrose · Updated 18 October 2026

In short: have a clear purpose, tell people with signage, avoid audio, collect only what you need, keep footage secure, delete it when you no longer need it and be ready to give people access to footage of themselves. The Privacy Commissioner recommends doing a Privacy Impact Assessment before you install.

Does the Privacy Act apply to my CCTV?

Yes, if your cameras capture identifiable people. The Office of the Privacy Commissioner (OPC) states that CCTV records footage of people, which can be stored, shared or changed, so how you use it must comply with the Privacy Act 2020. The Act applies to "agencies", which includes businesses, schools and organisations of every size.

Before you install: decide and document

The OPC says that before installing cameras you need to know:

  • your purpose for using CCTV
  • whether the cameras need to record audio as well as video
  • how you will use the footage
  • how you will tell people the cameras are there
  • who can access the cameras and footage
  • how long footage will be kept
  • how it will be kept secure
  • how you will handle someone asking to see footage of themselves

The OPC recommends a Privacy Impact Assessment (PIA) and publishes guides and templates for it. A PIA does not need to be long for a small site, but writing these answers down and turning them into a short CCTV policy is good practice and helps if your system is ever questioned.

The privacy principles that matter most for CCTV

Purpose and necessity (IPP 1)

Collect personal information only for a lawful purpose connected with your business, and only if it is necessary for that purpose. Theft prevention, staff safety and investigating incidents are common purposes. The OPC advises collecting the least amount of information you can.

Telling people (IPP 3)

People need to know they are being recorded. Most businesses use signs. The OPC says signs should be clear and obvious, say who owns and operates the system, and give contact details if that is not already obvious. If you record audio, you must tell people.

Fair and not unreasonably intrusive (IPP 4)

CCTV cannot be used in a way that is unlawful, unfair or unreasonably intrusive. The OPC says cameras should not record audio if video is enough, and should not move if a fixed view will do. Areas where people expect privacy, such as toilets and changing rooms, are generally not appropriate places for cameras. Hidden cameras are only justified in limited situations and need a very strong case.

Security (IPP 5)

Protect footage from loss and misuse: limit access to authorised people, use individual logins, secure the recorder physically and keep remote access locked down.

Access requests (IPP 6)

People have the right to ask for personal information about themselves, and that includes CCTV footage. The OPC's guidance is that your starting point should be to give the person access to footage that identifies them. The first step is to secure the footage immediately so it is not overwritten. You can crop or pixelate other people to protect their privacy, and the OPC is clear that not having the technology to redact footage is not a good reason to refuse access. Check the requester's identity before releasing anything.

Retention (IPP 9)

Do not keep footage longer than you need it for your purpose. The OPC recommends securely disposing of information once it is no longer needed. Set a defined retention period on your recorder so old footage is overwritten automatically, and preserve specific clips only when there is a reason, such as an incident or an access request.

Disclosure (IPP 11)

Only share footage in ways the Act allows, for example with Police when it is needed to help prevent, detect or investigate an offence. Keep a record of what you shared, with whom and why.

What changed in 2026: IPP 3A

The Privacy Amendment Act 2025 added a new principle, IPP 3A, which came into force on 1 May 2026. It requires agencies that collect personal information indirectly (from someone other than the person concerned) to take reasonable steps to tell that person, unless an exception applies. Most businesses' own CCTV is direct collection, but if you receive footage or personal information from another organisation, such as a landlord, neighbouring business or another agency, check the OPC's IPP 3A guidance.

Privacy breaches

If footage is hacked, leaked or shared inappropriately, that can be a privacy breach. Under the Privacy Act 2020, a breach that has caused, or is likely to cause, serious harm must be notified to the Privacy Commissioner and the affected people as soon as practicable. Good system security is the best prevention.

A practical checklist

  1. Write down why you need each camera and what it should see.
  2. Aim cameras at your own property and avoid neighbours' windows and private spaces.
  3. Turn audio recording off unless you have a strong, documented reason.
  4. Put clear signs at entrances saying CCTV operates, who runs it and how to contact you.
  5. Tell staff about workplace cameras and include them in your policies.
  6. Set a retention period on the recorder and limit who can view and export footage.
  7. Use individual logins, change default passwords and keep firmware updated.
  8. Have a simple process for access requests and Police requests.

When we install CCTV, we set systems up to support this: audio off by default, individual user accounts, defined retention and camera views agreed with you.

Frequently asked questions

Do I legally need CCTV signs in New Zealand?
The Privacy Act requires you to take reasonable steps to make people aware they are being recorded, who is collecting the footage and why. The Privacy Commissioner notes that most organisations do this with signage, which should be clear, obvious and say who owns and operates the system.
Can my business CCTV record audio?
The Privacy Commissioner advises that CCTV generally should not record sound, because audio is much more intrusive. If your equipment can record audio, the OPC suggests switching it off. If you do record audio, you must tell people.
How long should we keep CCTV footage?
The Privacy Act does not set a fixed number of days. You must not keep footage longer than you need it for your purpose. Choose a retention period that suits your purpose, document it and set the recorder to overwrite automatically.
Someone has asked for footage of themselves. What do we do?
First, secure the footage so it is not overwritten. Then check the person's identity and confirm they appear in the footage. The Privacy Commissioner's starting point is that you provide footage that identifies them, while protecting other people in it, for example by cropping or pixelating.
Can we give footage to the Police?
Generally yes, where disclosure is needed to help prevent, detect, investigate or prosecute an offence. Keep a record of what was released and why.
