Jailed National Finance director Trevor Ludlow will remain behind bars after the Court of Appeal rejected his appeal against his sentence.
Ludlow was convicted in 2011 of seven charges brought by the Serious Fraud Office, including six charges of theft by a person in a special relationship and one of false accounting.
He was sentenced in Auckland District Court by Judge Josephine Bouchier to five years and seven months in jail.
Ludlow later pleaded guilty to eight charges brought by the Financial Markets Authority, including one count of misstatement in a registered prospectus and seven counts of making false statements.
An extra nine months was added to his sentence by High Court Justice Kit Toogood, bringing his total sentence to six years and four months in prison.
