Members of Sunday night's Dancing with the Stars live audience suffered minor injuries after falling backwards from stepped seating.
An audience member told the Herald that three people fell "from a reasonable height" during the night.
Another witness said they saw two people in the third row fall backwards, disappearing from view.
"It was pretty dramatic at the time. We didn't see them again."
A MediaWorks spokesperson said it was a minor incident.
"Three people were so engrossed in the show they lost their balance and fell a short distance.
"It is unlikely to happen again, however we have handled this in accordance with our OSH policy and we are modifying that part of the seating to ensure there are no repeats."
According to the witness, a spokesperson came out shortly afterwards and said they had been checked by St Johns, were fine and had gone home.
But more audience members have spoken out about the incident.
Lesley Lomas was sitting three seats away from one of the ladies that fell and said the crew initially blamed them, claiming "they must have been swinging on their seats''
"This was not the case at all as it was a bit of wood on the floor that gave way. It was very traumatic and I ended up leaving not long after as I didn't feel comfortable in my seat after that. I was encountered by an older crew member outside who gave me and my mother grief for leaving early [10 minutes early] and also gave attitude to a pregnant lady who left early as she could no longer take sitting down. Was not impressed."
Bev Lomas was sitting two seats away and said there was no backing wall behind them, "just a rail with a big gap in the middle".
"It was not the ladies fault. As crew said, we were not allowed to leave, although we were all shaken. All they were interested in was recording, not impressed with the way they handled things."
St John Ambulance confirmed they arrived at South Pacific Studios Tolich Pl studios in Henderson at 9.05pm.
The patients were treated for minor injuries at the scene and were not transported to hospital.
