In the first case, a beneficiary was given a loan despite telling NTMC she had personal debts of $30,000.
Another case saw a beneficiary given a loan despite having only $1.65 in her bank account at the time of entering into the agreement.
And in the third case, NTMC staff approved a loan to a sickness beneficiary without asking for any documentation other than her passport and driver's licence.
"In all these cases the commission is concerned that either DFL obtained insufficient information about the borrower's financial affairs, or it didn't sufficiently take into account other relevant information," Rawlings said.
"While NTMC was DFL's agent in all three cases, in our view NTMC did not make sufficient enquiries about the borrowers' ability to repay the loan to ensure that DFL complied with its obligations."
DFL has advised the commission that it now ensures its dealers satisfy a checklist of reasonable inquiries before approving finance. It now also reserves the right to undo agreements made by dealers upon review of documentation.
Rawlings said: "We acknowledge that DFL had begun developing its procedures before our investigation and that it has settled the debt of two borrowers."
