Palmerston North police are concerned about the high number of booze-fuelled crimes in the city at the weekend.

Nine people were caught drink driving between Friday night and Sunday morning - a number described as "disturbing'' by Acting senior sergeant Mike Yates.

The legal drink driving limit for an adult is 400mg of alcohol per litre of breath but the offending drivers had readings ranging from the mid 400s to 1100, Mr Yates said.

"It's concerning that people are still consuming alcohol and driving and putting the public at risk'', he said.

One of the alleged drunk drivers was also facing reckless driving and failing to stop charges, he said.

Mr Yates said the arrests were not part of an operation targeting drink drivers.

Three rowdy parties, two on Colombo St and one on Church St, were shut down after neighbours reported fighting, excessive noise and disorderly behaviour.

No arrests were made but Mr Yates said it was disappointing to see the continued messages about host responsibility were not getting through to some people.

Police made 33 arrests made at the weekend.
