Query Information

In New Zealand, the alcohol limit for drivers aged 20 years and over is 250 micrograms (mcg) of alcohol per litre of breath and the blood alcohol limit is 50 milligrams (mg) per 100 millilitres (ml) of blood. If you are under 20, the alcohol limit for drivers is zero. You must not drive if the amount of alcohol in your breath or blood exceeds these limits.
