The commission said that in sentencing, Judge David Sharp said it was "cynical and deliberate" offending. He said the repossessions were "reprehensible" and were "used as a direct means of coercion".
Twenty-nine charges were for adding interest and costs to a loan balance after repossession, when that is not allowed under the Credit Repossession Act.
"One borrower declared herself bankrupt when told her loan had ballooned from about $9,000 to $57,000. In fact she had less than $2,500 to pay at that time," Borrowdale said.
Ten charges were for misrepresentations about adding interest to loans, beyond amounts in attachment orders issued by the courts. The final three charges were for misrepresentations about the benefits of refinancing with Budget Loans.
"These were particularly serious breaches of the Fair Trading Act," Borrowdale said.
"Lenders must not misrepresent their rights under loan contracts and they must act within the law. They cannot require borrowers to pay amounts and extra costs they do not owe, as happened time and time again with Budget Loans."
During the relevant period the directors of Budget Loans were Allan Hawkins and his son Wayne Hawkins.
"The commission is seeking banning orders against both men, following this sentencing and the earlier conviction of Budget Loans on 34 charges under the Fair Trading Act in 2010," Borrowdale said. "As our application is before the courts the commission will make no further comment on it at this time."
