Former Hanover director Mark Hotchin has labelled civil action against the company's former directors and promoters as "ill conceived".
The Financial Markets Authority is suing Hotchin, Eric Watson, Greg Muir, Bruce Gordon, Sir Tipene O'Regan and Dennis Broit over allegedly misleading or untrue statements made in Hanover offer documents.
The FMA is seeking compensation for investors who put $35 million into Hanover Finance, Hanover Capital and United Finance between December 2007 and July 22, 2008.
The market watchdog is also seeking penalty orders against the defendants, and if the claim is successful, the former directors and promoters could each face fines of up to $5 million.
The amount of the fine, if any, is determined by the court but the 10 causes of action filed against the six men each carry maximum pecuniary penalties of $500,000.
