The Government's being told it shouldn't be bringing in Police to monitor people in managed isolation and quarantine facilities.

An officer will be now stationed at each facility 24/7, after a second person escaped from managed isolation.

There were 5648 people in quarantine and managed isolation facilities at the moment, Air Commodore Darryn Webb told media earlier.

He said 99.97 per cent of people who had been through quarantine and managed isolation facilities since lockdown had followed the rules.

"Our job is to make sure the law is backed up by as many preventative measures as practicable."

New Zealand Police Association president Chris Cahill told Heather du Plessis-Allan it's not a good use of Police officers, when there are other people to do the job.

"Police can be called to deal with those one or two who don't follow the rules. And these people are humans, they are not criminals, they are not locked away in a jail."

He believes there are other highly trained and qualified people available to do the work.

"Police still have their day job to do. That demand for police resources continue.

"I believe they are better deployed elsewhere and other highly trained people can take over this role."
