A woman with two children in her car was caught driving almost four times over the legal breath alcohol limit.
Police said the woman was among a disappointingly large number of drivers caught drink driving in the Wellington and Wairarapa regions in the last week.
District road policing manager Inspector Mike Wright said the woman, who was stopped in Wairarapa last Friday, blew a breath alcohol reading of 935mcg per litre of breath - almost four times the legal limit of 250mcg.
A pensioner was also among those caught drink driving.
Police said the 74-year-old woman was stopped in the Wellington suburb of Lyall Bay on Sunday afternoon. She blew 685mcg - almost three times the legal limit.
The latest incident happened this morning, when a woman was stopped after a member of the public complained about how she was driving.
When breath tested the woman's reading was 725mcg.
Seventeen other motorists are facing drink driving charges laid in the last week.
Mr Wright urged those getting into their cars this weekend to heed drink driving messages.
"To the motoring public this weekend, the Wellington District road policing team asks you not to drink and drive - get a sober driver.
"Drive to the posted speed limit and have a great weekend."
