More than 3 million breath tests were carried on on New Zealand motorists in 2023 - the most in a decade - and police have now revealed who and where the worst drink drivers were. Provisional figures show there were 3,097,698 breath screening tests performed across the country in 2023, up 26 per cent from the 2.4 million completed in 2022. Police performed more breath screening tests in 2023 than the year before.

For drivers 20 and over, the limit is 250 micrograms of alcohol per litre of breath.
