Former NAB banker Andrew Matthews has been committed to stand trial after entering a guilty plea to one count of obtaining financial advantage by deception and one count of attempting to obtain financial advantage after rorting the bank's infamous introducer program.

NAB blew the whistle on the award-winning mobile banker alleging he and an accomplice defrauded the bank of more than $800,000 in the scam, and Mr Matthews allegedly used the proceeds to buy a Ferrari 430, the same model once owned by Donald Trump.
