NZ Traffic Stops & Breath Tests — Your Rights (2026)
About this article
Sourced from New Zealand Acts of Parliament (legislation.govt.nz), regulations, and official government guidance. Written in plain language for general understanding — this is educational content, not legal advice. Our editorial standards
What is this right?
Driving carries duties that ordinary public encounters do not. Under the Land Transport Act 1998, you must stop when signalled by an enforcement officer and give your name, address and date of birth and produce your driver licence (s 114). Police can run compulsory breath testing, including at checkpoints set up with no individual suspicion.
If you fail or refuse a breath or blood test, the consequences are the same — refusing is itself an offence and leads to penalties including disqualification. You can, and often should, get legal advice before deciding anything beyond the compulsory tests, but you cannot lawfully refuse the screening test itself.
When does it apply?
- You are pulled over while driving.
- You are stopped at a checkpoint.
- You are asked to take a breath screening or evidential test.
What to do at a traffic stop or checkpoint
- Stop, and give your name, address, date of birth and licence.
- Take the breath screening test — it's compulsory.
- Ask to speak to a lawyer before an evidential breath/blood procedure if you're unsure of your rights.
What should you NOT do?
- Don't refuse the breath test — refusal is penalised like failing, with automatic disqualification.
- Don't drive off or argue at the roadside.
- Don't give false details — it's a separate offence.
About Police Encounters in New Zealand
New Zealand has no single written constitution. Your rights when dealing with Police come from the New Zealand Bill of Rights Act 1990 (NZBORA), the Search and Surveillance Act 2012, the Policing Act 2008 and the common law. NZBORA protects you against unreasonable search and seizure (s 21), arbitrary detention (s 22), and guarantees rights on arrest — including the right to a lawyer (s 23). There is no general power to demand your name just for being in public; that only applies in specific situations such as driving. If your rights are breached you can complain to the independent Independent Police Conduct Authority (IPCA).
Emergency: 111. Police non-emergency: 105.
