Three directors of failed finance company Capital + Merchant are appealing against their jail sentences.
The company collapsed in 2007 owing $167 million to 7500 debenture holders.
Directors Neal Nicholls and Wayne Douglas were sentenced in August to seven years and six months in jail on fraud-related charges.
Owen Tallentire, who was the chief executive, is serving a five-year sentence.
Their appeals will be heard in the Court of Appeal on 7-8 November.
