Troy said one person blew over twice the legal limit when they were breath-tested shortly after picking a child up from school.
“This behaviour is not only unacceptable and irresponsible, but it puts all road users at risk.”
Another driver was stopped in Taupō about 12pm and blew over four times the legal limit.
The legal alcohol limit for a fully licensed driver over 20 years of age is 250 micrograms per litre of breath.
The limit for anyone under 20 is zero.
Troy urged the public to make better decisions before getting behind the wheel.
“If you are drinking, don’t drive. Even if you have only had one or two, it is not worth the risk.
“These results continue to demonstrate why you can expect to see police breath-testing motorists anywhere, at any time of the day.”
Troy said infringement notices had been issued for the drivers.
