Unionised firefighters in Auckland are refusing to use their lead fire truck because of concerns about its safety.
A "long list of faults" had led the New Zealand Professional Firefighters Union to blacklist the MAN appliance - which also carries the jaws of life crash tool - at the Auckland City station.
It's the first time in 20 years that firefighters have been forced to blacklist an appliance due to safety concerns, the union says.
"The union considered the risk to firefighters and the public to be too high," said northern branch secretary Boyd Raines.
The union didn't specify what was wrong with the appliance, but a newsletter says a "spreadsheet of faults and failures" is being compiled.
The Fire Service wasn't immediately available to comment on the problems, but a spokesman told media a spare appliance had been brought in while the MAN was out of use.
