North Shore students have been banned from hugging during school hours because too many of them - mainly girls - were consistently arriving late to their classes.
Takapuna Normal Intermediate School deputy principal Sue Cattell said teachers last week suggested to students that they keep the hugs outside of the school day.
A trend among groups of year 8 students - 12- to 13-year-olds - had driven the call, Mrs Cattell said.
"It's just a little thing that they're doing. It got out of hand towards the end of morning tea time especially. There would be groups that got back to class 10 to 15 minutes late because they were going around making sure they'd hugged the whole group before they got back to class.
"Obviously they'll see their friends again at lunchtime so there's not a need for a great big hug. [The teachers' talk] was to remind them that this is like their place of work and they need to be back on time."
