The woman, in her 20s, was flown by helicopter to Christchurch Hospital’s emergency department on Wednesday after being injured in a fall at Leap Dunedin Trampoline Park.
In a statement issued yesterday, management said the injury happened when the woman "landed awkwardly" while attempting an acrobatic trick.
The park’s staff were concerned for the woman’s health.
"Our immediate thoughts are with the woman and her partner, and we are deeply concerned for her welfare," management said.
Park users were given a safety briefing before every session.
"There was no failure of any of the park equipment, which undergoes regular inspection and maintenance."
Since the park opened in November 2014, 100,000 people had visited and the injury was the first of "this nature", management added.
A WorkSafe New Zealand spokesman said the department had been notified of 28 incidents at the park since the start of 2015. However, only Wednesday’s accident was serious enough to require an investigation.
A WorkSafe inspector visited the park after the incident.
In October, WorkSafe announced it would send inspectors to trampoline parks across New Zealand in response to "a spike in trampoline injuries since 2014".
WorkSafe general manager operations and specialist services Brett Murray said park operators would be given a bulletin containing information on meeting obligations around health and safety.
"We will also be taking a closer look at the designers and installers of these parks to make sure they are all doing everything reasonably practicable to manage the risks for staff and users of the parks."
Figures from ACC revealed trampoline injury claims in Dunedin city soared from 157 in 2014 to 459 in 2015.
Claims were for injuries received on private and commercial trampolines.
More than 10,000 people nationally made claims for trampoline-related injuries last year, costing more than $4million, the data showed.
