Can my NZ business collect biometric information from staff or customers?
Yes, but only if you comply with the new Biometric Processing Privacy Code, which took effect in 2025. The Code sits on top of the Privacy Act 2020 and adds specific rules for any agency that collects or processes biometric information. You must carry out a proportionality assessment (essentially a PIA), have clear notification, consider less privacy-intrusive alternatives, and meet heightened transparency requirements. Retail, workplace and identity verification use cases are all in scope.
What did the Biometric Processing Privacy Code change?
The Code introduced specific obligations for biometric processing that don't apply to ordinary personal information. The most important changes are: a mandatory proportionality test before deployment, specific notification requirements, restrictions on certain use cases, and a requirement to consider alternatives. The Code applies to biometric identification and categorisation, including facial recognition, fingerprint, voice and behavioural biometrics. If your business uses any biometric technology, you need to document your compliance now.
Do I need consent to use facial recognition in my business?
Consent is not always required, but it is usually the safest legal basis. The Privacy Act 2020 allows collection of personal information for a lawful purpose connected to a function or activity of the agency, but the Biometric Processing Privacy Code adds a proportionality test. For retail loss prevention, that test is particularly demanding and the Privacy Commissioner has issued guidance indicating that many deployments will not meet it. Don't deploy facial recognition without a written assessment and, ideally, legal sign off.
