More than 600 attend the school and there were also concerns that some children's feelings could be hurt if they were left out.
Parent Lorna Subritsky, whose daughter attends the school, said she could understand it might be annoying for teachers for have stragglers to their classes but the issue could be dealt with by addressing the lateness, not the physical contact. Parents could have spoken to their children in order to cut down the time-wasting.
"It's like using a sledgehammer to squash an ant. I thought it was pretty bizarre," she said.
President of the New Zealand Association for Intermediate and Middle Schooling Gary Sweeney said he'd noticed the same trend in his own school, Pukekohe Intermediate.
"I do not really have a comment about whether another school is right or wrong with how they approach various issues. Being late to class is certainly an issue and if the school has put in place a rule to help hurry kids along to class, then I would support that."
