Do you need a fast set up and interlock installed?
Most people who call us have never dealt with an interlock before and that's why we're here. We'll get you set up fast and walk you through each step.
We're ready to help! Call our team to get set up within minutes.
You've probably got questions... what will it cost, are they easy to use, who sees my data, what if other people need to use my vehicle? Those are examples of the questions we answer every day. When you call us you'll talk to a Kiwi and you won't feel judged. We've been installing interlocks in New Zealand since 2012 and so far we've helped more than 20,000 drivers through the interlock programme.
We're New Zealand's largest interlock provider and we got there one driver at a time, by treating every person who called us the way we'd want to be treated.
Using an interlock is easy, easier than most people expect. An interlock is a small breathalyser wired to your car's ignition. Before you start the engine, you blow into it and as long as it doesn't detect alcohol, the car starts as normal. Every so often while you're driving the interlock will call for a test to confirm you're still good to go. All interlock data is recorded for NZTA as part of your licence conditions.
Our Kiwi support team is here from 7am to 5pm to help you understand your interlock device, prevent violations, and stay compliant. Whether you are unsure about morning after readings, multiple drivers, or servicing, we provide clear, pressure-free advice.
Contact us for friendly help with any part of the interlock programme.
People tell us the process was easier than they thought — supportive, straightforward, and a relief during a stressful time. We've installed over 20,000 interlocks in the last decade, and our goal is to make it as simple as possible for you.

An alcohol interlock is a breath testing device connected to your vehicle that prevents the engine from starting if alcohol is detected.
You take a breath test before driving and during random prompts. All activity is recorded for NZTA review.
Costs depend on subsidy eligibility, monthly lease fees, installation, and removal.
Most installations take about an hour and can usually be booked within one to two days.
No. The vehicle will only start once you provide an alcohol free sample.
Removal only occurs when the NZTA confirms programme completion.
Each driver must provide their own breath sample. All activity is logged.
The NZTA reviews monthly reports through the approved service centres.
The device is small, discreet, and similar in size to a handheld breathalyser.
A breathalyser checks your level, while an interlock device controls vehicle ignition and records data for compliance.
