Papamoa Village Park Ltd's lawyer Kate Barry-Pacino argued a fine starting at $25,000 fine was appropriate given the special and unique circumstances of this case.
The defendant had not made a profit from these dwellings, and the intention was to improve the buildings to make them safe and affordable homes for unit owners, she said.
Judge David Cameron said this was clearly not a mere oversight.
"I agree with the council's prosecutor there was a high degree of carelessness by the park director who gave incorrect advice to Venture Developments when a simple phone call to the council would have elicited the correct information," he said.
In October Venture Developments was fined $54,000 for the same charge in relation to all 28 units built at the park between October 2016 and February 2018.
