The parole board described Bennett's conduct in prison as "above reproach" and said he had been working in the garden.
Bennett was ashamed of what he had done and took responsibility for his offending, the board said.
But there remained questions in the mind of the board about Bennett's insight into his offending.
"The senior psychologist who undertook the assessment noted that the nature of Mr Bennett's offending and his low risk of re-imprisonment, mean that he is not eligible for any intervention offered by the prison...we are in no doubt that such an intervention is required before he leaves prison," the board said.
"Accordingly, we request that Mr Bennett's case manager engage with him in the preparation of an appropriate safety plan identifying his warning signs, high risk situations and the strategies Mr Bennett and his supporters can take to minimise his risk of returning to the situation that led to this offending...the board could not be satisfied that Mr Bennett would not pose an undue risk to the safety of the community until this crucial step is undertaken," the board's decision said when rejecting parole.
Bennett is due to come back to before the parole board in December.
Bennett, in 2012, pleaded guilty to six representative charges under the Crimes Act relating to more than 900 separate incidents of dishonesty using a document, and a further two charges of false accounting.
Between April 2005 and March 2011, he was the sole director of Christchurch-based DataSouth Group, where he orchestrated the bold scam.
The trained accountant created false documents relating to the lease of IT equipment to fraudulently obtain funds from SCF totalling $65.5 million and falsified entries in DataSouth Finance financial statements by an estimated $38 million to retain the ongoing finance facility.
The resulting loss to SCF was at least $23 million.
Bennett used the dishonestly obtained funds to repay earlier false lease agreements, similar to a Ponzi scheme, and to meet business expenses.
He also used the money to fund his high-rolling lifestyle.
He partied in luxury Sydney waterfront apartments, surrounded himself with models and actresses, was chauffeured in BMW and Mercedes-Benz cars and "drank Dom Perignon like it was Speight's".
