The former chief executive of Capital + Merchant Finance Ltd has been given an extra prison term and two other directors have been sentenced to home detention for misleading investors.
All three pleaded guilty to charges laid by the Financial Markets Authority.
Capital + Merchant Finance collapsed in 2007 owing $167 million to about 7500 investors.
Former director Colin Ryan was given a sentence of seven months home detention and 300 hours of community work.
He will pay $100,000 in reparation to the company's receivers.
Another former director Robert Sutherland received six months home detention and 300 hours of community work and will pay $60,000 in reparation.
Former chief executive Owen Tallentire, who is already in jail on serious fraud charges, received an extra 12 months for the latest charges.
They relate to untrue statements made in Capital + Merchant's prospectuses in 2007 and misleading statements made in some advertising material.
Justice Venning told the High Court in Auckland written statements from many investors showed they had suffered depression, financial hardship and health problems following the loss of their funds.
