Land Transport Act 1998, s 65B
A zero alcohol licence is a three-year stage that repeat drink-drive offenders and serious first-time offenders must go through after being on an alcohol interlock licence for at least 12 months (see above). After this zero alcohol stage is over, they can then apply for a standard licence.
With a zero-alcohol licence, you can’t drive with any alcohol in your breath or blood at all. The licence lasts for three years; after that you can apply for a standard licence.
