At the Whangarei police station she was unable to complete an evidential breath test so a blood sample had to be taken.
She refused to tell police what type of alcohol, or how much, she had been drinking. The blood test recorded a level of 424 milligrams of alcohol per 100 millilitres of blood, more than five times the legal limit of 80mg.
Ash was sentenced to three months' community detention, 150 hours' community work, 15 months' supervision and indefinitely disqualified for her third drink-driving conviction.
Northland has some of the highest rates of drink-driving in the country, particularly repeat offenders.
