Land Transport Act 1998, s 119
The police can pursue you onto your property and into your home to carry out a breath-alcohol test if:
they suspect you’ve been driving recklessly or dangerously, or driving under the influence of drink or drugs, and
you failed to stop and stay stopped for the police, or failed to give them your details and other necessary information when required.
If necessary, the police can use force to get onto your property or to enter your home.
