Guilt is wracking an untrained amusement ride worker who "swapped" his post at a giant inflatable slide shortly before it collapsed and injured six children at the Masterton A&P Show on Saturday.
Carterton man Matthew Martin said he and partner Jessica Knutson had been part of a group of 11 casual operators who worked for Waikato-based company Event Fun Unlimited at the annual event at the Solway Showgrounds.
He said nine people had failed to appear for a cursory induction meeting for casual operators of the free rides on Saturday, and he blamed the under-staffing for the "solid" 12-hour shift he and his partner were forced to work without any breaks.
There were also five trained operators and Event Fun Unlimited manager Eric Gerritsen on hand as well, Mr Martin said, although he only once sighted Mr Gerritsen and could not find any experienced crew members when needed.
"There was no safety meeting, no training and nobody said anything about age limits or how many children could go on the ride at a time. It was so unorganised," Mr Martin said.
