Mainzeal's Richard Yan is appealing the High Court ruling which demanded he and other directors pay $36 million, saying the decision had erred in law in its findings.
David Chisolm, acting for Yan, this morning confirmed the case going to the Court of Appeal.
The position of ex-Prime Minister Jenny Shipley, ex-Mainzeal chief executive Peter Gomm and director Clive Tilby is yet to be announced. They are all represented by Chapman Tripp.
Yan's notice of appeal outlined the grounds for taking the matter to the higher court, including claiming there was no deterioration in Mainzeal's financial position between when breaches of the Companies Act were said to have occurred in 2011 and when the company went into liquidation in 2013.
Yan was found to have breached the act and caused loss to others including creditors.
