Trampolines throughout the country are not up to standard, Consumer NZ has found.
Five popular trampoline brands were tested and only one met critical safety checks.
The tests assessed the risk of brain injury from a child's head colliding with the safety padding above the frame.
The Springfree R54, a soft-edge trampoline with its frame and springs beneath the jumping mat, was the only trampoline to pass the impact tests.
None of the traditional trampolines (those with the springs around the edge of the jumping mat) passed the impact tests.
Two trampolines were also rated poor for bounce quality.
These were the Parklands TC-1004S and the Gametime TR-10 Combo-L.
ACC statistics show about 7600 people injure themselves on or around a trampoline each year.
