A woman caught driving while allegedly almost seven times the legal alcohol limit told police she had been drinking wine at a funeral.
Senior Sergeant Anthony Bond said police were called to a Perth St address in Oamaru at 2pm on November 10.
They had received complaints that a vehicle was crossing the centre line.
Police tracked the vehicle to Greta St where it was stopped in the middle of the road before being parked in a driveway.
Police spoke to the driver, a 57-year-old woman, who showed signs of intoxication.
Snr Sgt Bond said she admitted to drinking wine at a nearby funeral.
The woman recorded a breath alcohol content of 1680mcg, nearly seven times the legal limit of 250mcg.
Her licence was suspended for 28 days and police were awaiting blood results before a charging decision was made, Snr Sgt Bond said.
