The humble family trampoline is under the spotlight, with calls for compulsory safety standards for the backyard favourite.

Standards New Zealand axed the voluntary trampoline safety standard just before Christmas.

Safekids Aotearoa director Ann Weaver is concerned by the move, saying around 300 children are hospitalised every year with trampoline-related injuries.

"That's a serious injury. We're not talking about the little bumps and scrapes and small sprains and things like this."

Safekids Aotearoa wants to see a mandatory safety standard introduced, to help reduce injury numbers.
