The victim sustained compression fractures of several vertebrae and fractures to his thumb. He was off work for three months.
The gate was installed in mid-2013. Investigation showed about a month later two employees found bolts securing a "stop" were coming loose. On two occasions, they tightened them. Another time they got petty cash through a service administration manager for a type of glue and a spring washer for the gate.
Carrying out repairs and maintenance work on the gate was not a task within their duties and responsibilities. While they and the service and administration manager were aware there were issues with the gate, a work order was not raised.
Judge Turner said the consequences for the victim were emotionally, physically and, to a lesser extent, financially significant. The victim was in hospital for five days and in a body cast for three months. He was still recovering. He was now on light duties two days a week. Whether he had any permanent disability remained to be seen.
"He and his partner struggle to plan for the future. He feels his life remains in limbo."
Prosecuting counsel Sarah Backhouse, of Wellington, said the practicable steps the company failed to take were identifying the gate as a potential hazard, and ensuring the defects found in the gate were repaired by suitably qualified people.
Counsel Tim Clarke, of Auckland, said a large number of remedial steps had been taken to ensure nothing like the accident would happen again. He also made a formal apology to the victim and his partner, who were both present in court.
Imposing sentence, the judge said the company's level of culpability was increased by its failure to take steps although aware of the potential hazard.
