Local principals say a bottleneck of police checks on staff and parents is jeopardising school camps and stalling new teacher registrations.
Hastings Intermediate principal Andrew Shortcliffe said the lengthy wait times were the reason his pupils were tenting on the school's back field for camp this week.
It was taking too long to get police checks on parent volunteers.
"We were doing a 3-day away camp but we changed it to a 3-day at-school camp with the tents on the back field. The teachers are the only ones who have a police vet."
The school had received a note saying the police vetting service was experiencing "unprecedented demand" this year, and the wait time was 21-28 working days.
