ACC regrets its handling of hunger striker who has been living on the street outside its head office in Wellington, the agency's chairwoman says.
Mike Dixon-McIver, 75, has been locked in a six-year battle with the corporation since it tried to prosecute him for fraud and he had a mental breakdown.
The case was thrown out in 2008, with Dixon-McIver declared bankrupt two years later.
He pursued the case and in January this year was awarded full recovery of costs by the District Court, which heavily criticised ACC for its action.
Dixon-McIver wants compensation for his mental injury and financial loss, and rejected a previous apology and settlement offer from ACC.
ACC chairwoman Dame Paula Rebstock was asked about the case at the transport and industrial relations select committee review of ACC's financial performance today.
"The case was ultimately thrown out and we were not found to have handled the case the way we would like to have or should have and for that reason the court ordered a payment be made and we made that payment," she said.
"Having said that the board and management and staff of ACC are very concerned about Mr McIver's health and wellbeing.
"We are engaged with him - I don't want to discuss the particulars of the case here - other than to say we have offered mediation ... we want to work with him and we need to be constructive about that."
