§ Country Overview & Administrative Framework

Alcohol Interlock Programme in NZ: Sentences, Smart Start Devices & Zero Alcohol Licences

Under Section 65A of the Land Transport Act 1998, New Zealand courts are statutorily required to sentence qualifying drink-driving offenders to an Alcohol Interlock Order. This mandatory sentencing regime applies to repeat drink-drivers convicted within 5 years, or first-time offenders convicted with very high breath alcohol readings (exceeding 800 micrograms per litre of breath) or blood alcohol levels exceeding 160 milligrams per 100ml.

Core components of the Interlock Programme :

  • 28-Day Disqualification Phase : The court first disqualifies the driver for 28 days. After day 28, the driver can apply for an Alcohol Interlock Licence ;
  • Ignition Interlock Device Installation : An approved electronic breathalyzer unit (provided by certified vendors like Smart Start or Draeger) is wired into the vehicle's ignition system. The vehicle will not start if alcohol is detected on the driver's breath ;
  • Rolling Retests & Data Downloads : The device requires random re-tests while driving and logs all attempts. Monthly data downloads are transmitted to Waka Kotahi to verify zero alcohol compliance ;
  • Exit to Zero Alcohol Licence : After completing at least 12 months with a clean record (no positive alcohol attempts in the final 6 months), Waka Kotahi grants an exit certificate allowing the driver to hold a Zero Alcohol Licence for 3 years.

Driving a Non-Interlock Vehicle Violation

Driving any vehicle not fitted with an approved interlock device while holding an Interlock Licence is a criminal offence under Section 32, resulting in immediate vehicle impoundment and cancellation of the programme.

Resetting the 6-Month Clean Clock

Any positive alcohol breath reading or missed calibration download resets the required 6-month clean violation-free period back to day zero, delaying full licence recovery.

Frequently Asked Questions & Answers
