Understanding the Alcohol Interlock Programme in New Zealand
The Alcohol Interlock Programme is a Waka Kotahi (NZTA) mandated pathway designed to help drivers safely return to the road.
Rather than a punishment, it’s a structured, monitored system that supports long-term behaviour change and road safety.
How the programme works
- You begin with an interlock licence, allowing you to drive with an approved interlock device
- Your driving behaviour is monitored through data logs when you apply to exit the programme
- After meeting NZTA’s requirements, you progress to a zero alcohol licence
- You can then apply for your full licence after a period of 3 years
This process creates a clear, achievable path back to unrestricted driving.
What the Interlock Licence Allows You to Do
An interlock licence enables you to:
- Drive legally after your disqualification period
- Operate any vehicle fitted with an approved interlock device
- Demonstrate safe, alcohol-free driving behaviour
The interlock device acts as a safety safeguard, preventing the vehicle from starting unless a clean breath sample is provided.

Frequently Asked Questions
What is an alcohol interlock licence and how do I get one?
An alcohol interlock licence allows you to drive a vehicle fitted with an approved device. After your 28-day disqualification, you apply through a licensing agency and begin the programme once approved.
What does the interlock device do?
The device prevents your vehicle from starting unless you provide an alcohol-free breath sample using police-grade technology. If you have alcohol in your breath, the interlock will prevent your vehicle from starting.
What are my responsibilities during the programme?
You must get your interlock serviced every month, provide clean breath samples, and follow all licence conditions. Non-compliance may extend your time in the programme.
How long do I stay on the programme?
Most drivers remain on an interlock licence for at least 12 months, followed by a zero alcohol licence period before applying for a full licence.
What happens after interlock removal?
After completing the programme and meeting all conditions, your device is removed, and you transition to the next licence stage.
How much does an interlock licence cost?
The interlock licence cost varies depending on installation, monthly fees, and eligibility for subsidies. Contact us for a tailored breakdown.
