Consultation closes on 8th May

We’re asking New Zealanders to have their say about new draft rules that would outline how biometrics can be used. Biometrics are physical and behavioural characteristics (face scans, fingerprint scans, voice recordings) that can be used to identify individuals or work out things about them using technology like facial recognition.

New Zealand doesn’t have specific rules for biometrics. We’re proposing that we create some, in a code of practice under the Privacy Act 2020.
