Do you need a fast set up and interlock installed?
If you have been issued an Alcohol Interlock Order, the interlock is the legal pathway to driving again in New Zealand. While the process can feel technical and overwhelming at first, it follows a clear sequence. Once you understand each step, from approval through installation and into the transition phase, it becomes far more manageable.
This guide explains the full process in plain language, with a focus on what matters most to licence holders: timelines, costs, and how to avoid delays so you can legally regain your independence.
An alcohol interlock is a breath-testing device installed in the ignition of your vehicle. Before the engine starts, you must provide a breath sample that registers zero alcohol. The system also requires random tests while driving, it beeps to let you know a test is required and it gives you 5 minutes to take the test.
The interlock NZ programme is designed as a safety measure. It allows you to drive legally under supervision, while demonstrating consistent compliance with zero-alcohol requirements.
For licence holders, the device quickly becomes part of your daily routine. You feel the click of the handset connecting, hear the beep prompting a test, and wait a few seconds for the clear signal to start the car. Over time, it becomes familiar and predictable.

The process to obtain an interlock licence follows a set order. Missing a step can delay approval, so accuracy matters.

Many drivers want to understand the cost of an alcohol interlock device cost in NZ before booking an installation. Monthly leases start from $149 and include more than just the device. Your lease covers warranty for theft or faults, along with the required monthly calibration and servicing.
The standard installation fee is $199, with removal at the end of the programme costing $149. If you qualify for the NZTA subsidy, both of these fees are free. The subsidy also covers licence fees and contributes $50 per month toward your lease. The interlock device must also be serviced regularly to remain compliant. These visits are a NZTA requirement to download your interlock data, check the device, and calibrate it to detect and prevent faults that could affect your licence status.
Not sure if you qualify for the subsidy? Smart Start can help check your eligibility for financial assistance that may be available through the alcohol interlock programme subsidy. Eligibility depends on individual circumstances and Smart Start can explain how you can apply.

Support is available 24/7. If you have any questions about the device or compliance, local Kiwi staff are available tohelp quickly. All Smart Start staff have lived experience (they’ve all had an interlock installed in their vehicle). This means you’ll always be dealing with someone who truly understands the process and this ongoing, expert support is critical to completing your alcohol interlock program smoothly.
One of the most misunderstood steps comes after the interlock period ends. Completing 12 months with an interlock does not automatically qualify for your next licence (zero alcohol licence).
Once you’ve had your final interlock service, you must apply for your Zero Alcohol Licence. NZTA will review your data, and once they give you approval, you need to get your zero alcohol licence from a licencing agency. You must have your zero alcohol licence in hand before you can book your interlock removal. Your zero alcohol licence is held for three years. Please note that during this period, any alcohol detected while driving would have serious consequences.
Understanding this transition early helps avoid frustration and setbacks. Planning for licence changes ensures there is no gap where you are unable to drive legally.
If you are ready to move forward, booking early helps prevent delays. Smart Start Interlocks offers NZTA approved interlocks, nationwide service centres, and local Kiwi support throughout the process. Book your installation today and take the next step toward getting back on the road.
