Earlier this year, former Belgrave Finance Director, Stephen Charles Smith, 43, and an associate, Raymond Tasman Schofield, 49, were committed for trial on similar charges. A trial date has not yet been set.
A total of 60 charges have been laid against all three by the SFO, relating to $18 million in loans made by Belgrave Finance between June 2005 and March 2008.
The SFO alleges the defendants misrepresented to investors how their investments would be used and then used the money without authorisation.
Charges against the three have also been laid by the Financial Markets Authority (FMA). The charges will be prosecuted jointly with the SFO.
Mr Feeley said the two agencies had been working closely.
"We have a number of major cases coming to trial this year and, when coupled with ongoing investigations, it is a matter of commonsense to ensure that we maximise the skills and resources available across the public sector.''
Belgrave Finance went into receivership in May 2008, owing around 1000 investors more than $20m. It was liquidated in April 2010.
Mr Buckley was remanded at large and will appear for sentencing on August 30.
