The Shareholders Association is pointing to the long period of time it is taking to resolve fraud cases.
Two former directors of Five Star Finance, Nicholas Kirk and Marcus McDonald, were each sentenced in the Auckland District Court to more than two years in prison on Tuesday on charges of theft and lying to investors.
Five Star went into receivership in 2007 owing the investors about $46 million.
Shareholders Association chairman John Hawkins told Morning Report the sentences mean there will be some nervous people awaiting the outcomes of their fraud prosecutions.
It has taken about three years for the directors to be punished.
Mr Hawkins said he hopes that the wheels of justice will move a great deal faster when the new Financial Markets Authority starts operating next year.
