Ratepayers in Central Hawke's Bay lost almost $4 million when civil contracting company Infracon went belly-up in 2014.
At the time of the liquidation, the council was a 34 per cent shareholder of the company.
According to Earnest&Young Partner Stuart Mutch, who audited the Central Hawke's Bay District Council (CHBDC) for 2015, the local-government body wrote off its investment in Infracon last year due to the uncertainties associated with the recovery of funds.
Council chief executive John Freeman said as a result it lost its share of the company, which amounted to $3.7 million.
"At the end of the day it's a ratepayer loss because it was a ratepayer-owned company or our share of a ratepayer-owned company," he said.
