He blew 771 micrograms of alcohol per litre of breath.
His driving licence has been suspended for 28 days.
He is facing two charges of drink driving, careless use of a motor vehicle and driving while forbidden and will appear in the Whangarei District Court this week.
In another case, an Auckland man was arrested and charged with dangerous driving, failing to stop, driving while forbidden and unlawfully taking a motor vehicle after a police pursuit in Whangarei.
Ms Rouse said the 18-year-old allegedly stole a Subaru Legacy from Henderson, in west Auckland, on Friday and was seen speeding about 20km south of Whangarei that afternoon.
He reached speeds of 160km/h during a police pursuit when he also conducted passing manoeuvres.
Police abandoned the chase but he pulled over when police next sighted him.
He appeared in the Whangarei District Court on Saturday and was remanded in custody. Police opposed bail.
