Research by the University of Waikato showed:
If you blow above 250mcg you will be taken to the police station for a more conclusive breath test. If you are over the new limit, you could receive an infringement notive of $200 and 50 demerit points. You may also be forbidden to drive for up to 12 hours. Drivers who are over 400mcg of alcohol per litre of breath, or 80mg of alcohol per 100ml of blood, will face criminal sanctions.
Your limit is ZERO - that means you're not allowed ANY alcohol when you drive.
From 1 December 2014 the alcohol limited for drivers aged 20 years and over lowered from 400mcg of alcohol per litre of breath to250mcg.
The blood alcohol limited lowered from 80mg per 100ml of blood (0.08) to 50mg (0.05).
Alcohol is a factor in around 30 percent of New Zealand's fatal road crashes.
For every 100 alcohol- or drug-impaired drivers or riders who die in road crashes, 47 of their passengers and 16 sober road users die with them.
Over the last 10 years, fatal crashes caused by drink-driving have claimed the lives of around 1,100 people and caused serious injuries to another 5,300.
The average annual social cost of alcohol related crashes is $446 million.
How many people are killed in crashes involving drivers in the new adult infringement offence range (51 - 80mg of alcohol per 100ml of blood)?
Road crash data collected by police over 22 months recorded 53 drivers involved in fatal and serious injury crashes with a blood alcohol concentration level in the range of 51-80mg per 100ml of blood. These crashes resulted in 5 fatalities and 62 serious injuries.
