Students are borrowing more than ever as tertiary fees rise - and those who head overseas after study are likely to take much longer to repay their loan.
The annual report on the student loan scheme shows the average amount borrowed in 2013 was $8315, an increase of 6.3 per cent ($493) on the previous year.
The increase has been driven mainly by fee rises. In recent years New Zealand universities have hiked fees by the maximum 4 per cent allowable.
At June 30 this year, 721,437 people had a student loan. The average loan held by Inland Revenue was $19,731.
The median repayment time for all borrowers who finished study in 2011 is forecast to be seven years. Those who stay in New Zealand have an expected median repayment time of 5.8 years, compared with 15.2 years for those who will not always be based in the country.
