"They get many of these types of things."
Although Motat is loved by families with children fascinated by old technology, behind the scenes its board has a history of infighting. Veteran volunteer Alan Curtis took Motat Society chair Ian Hambly to the High Court last year and chief executive Jeremy Hubbard was "locked in a dispute" with Hambly for more than a year over Hambly's conduct as a road transport collection manager, the New Zealand Herald reported.
Bayly said there was no link between the complaint and the infighting.
One Motat insider said an issue could be pest control, with unusual contracts in place. Motat chief executive Jeremy Hubbard denied being aware of that being a problem.
The anonymous worker also said the general mood among staff was not good and people were quitting every month.
"It's an unhappy place to work."
