"He had done all his drinking in Auckland and could have easily crossed the centre line and smashed into an oncoming vehicle and killed someone."
The legal limit for motorists aged 20 and over fell from 400mcg to 250mcg on December 1 last year. Those with readings of between 251mcg and 400mcg are fined.
Mr Burrows said the driver has been bailed to appear in the Whangarei District Court on Wednesday.
In another case, a 26-year-old allegedly blew 633mcg when stopped by police on Marsden Pt Rd in Ruakaka on Friday evening. He was bailed to appear in court on March 25.
Both cases followed an 18-year-old who allegedly recorded 1301 micrograms of alcohol per litre of breath.
The limit for motorists under 20 is zero and for drivers aged 20 and over the limit is 250mcg.
The man, from Morningside in Whangarei, was stopped on Fourth Ave about 1am on Wednesday last week.
Police are shocked the teenager - with fives time the legal adult alcohol level - was able to actually drive.
