Fractures, dislocations and soft tissue injuries were among the most common reasons for claims.
Greytown School principal Kevin Mackay said mishaps were important to learning.
"There will always be accidents in school playgrounds," he said. "It's just not possible to wrap all the kids up in cotton wool and nor would we want to.
"Accidents are a part of life and a part of learning. Almost always a child who falls off a particular piece of equipment and hurts themselves, usually not seriously, will think much more carefully about how they do it next time."
The school encouraged children to engage in active play, he said. "It's all about managing risk and keeping it all in perspective.
"Our kids are still allowed to climb the trees within reason. If we see them miles up a tree they won't be allowed to do it for some time but it's fine if they're within reason - they love it.
"Occasionally we get a kid fall out of a tree, it's a part of what happens, but I've never had a kid fall out of a tree twice."
Mr Mackay didn't think teaching was any more dangerous than other professions.
"I had a teacher on ACC earlier in the year for quite some time. All she was doing was leaning on a chair and she slipped, put her hand out to stop herself and broke her wrist. There's just no way of preventing those things."
Nationally, 361,450 ACC claims were made by students in the past five years. The claims cost more ACC more than $100,000,000 in total.
The number of claims increased each year to 79,622 in 2014. The total cost of claims was higher in 2013, at $19,390,681.
The national figures for teacher claims were not readily available.
