The Inland Revenue Department will be able to recall student loans in full under legislation passed by Parliament today.
Revenue Minister Peter Dunne said the vast majority of borrowers met their repayment requirements and had no reason to worry, but serious defaulters would be dealt with.
"This bill allows Inland Revenue to recall those loans in full, with outstanding interest and penalties," Mr Dunne said during the third reading debate on the Student Loan Scheme Bill.
"This is not a harsh move. It is about fair and appropriate, real world consequences of the same sort you would face if you continued to remain in serious default on your mortgage."
Mr Dunne said it was "the last option" for dealing with those who consistently reneged on their repayment responsibilities, and would only be used when all reasonable efforts had failed.
