Civil proceedings are expected to be laid in the Hanover case as early as this week - but Eric Watson says they will "lack substance" and will be defended.
Mr Watson confirmed to the Herald yesterday that he expected a decision shortly on charges laid by the Financial Markets Authority.
"While I have not had any direct contact with the FMA regarding when they will deliver a decision, I understand that the FMA may issue civil proceedings in the near future.
"If this does in fact occur, it will be after a detailed investigation by the Commerce Commission, the Serious Fraud Office, the Securities Commission and then the FMA that began almost three years ago and concluded that there was no case for criminal charges."
He said the FMA concluded that there was no deliberate intention on the part of the directors of Hanover to mislead investors and that "while civil charges may follow, they [FMA] had a preference to settle rather than go through a lengthy legal process".
