A Central Hawkes Bay horse coach manufacturer has been fined $23,000 after pleading guilty to two cases of dangerous gasfitting.
The firm Classic Horse Coaches designs and builds customised horse coaches.
The Plumbers, Gasfitters and Drainlayers Board said two customers of Classic Horse Coaches complained they had problems with their refrigerators overheating.
When they were checked by licensed gasfitters and electricians the work was found to be unsafe and posed a danger to life from gas leaks.
The Board described the cases as ticking time bombs and said it hopes the sentence will serve as a deterrent to others.
