The Government plans to increase pressure on New Zealanders overseas to repay their student loan debt, but Labour fears a scheme that has student loans linked to some courses and not available to others.
Prime Minister John Key said the Government would rein in the student loan scheme "in a big way" while addressing the Colliers International "Research Hits the Road" event in Auckland today - though he committed to keeping them interest free.
He said the scheme was politically popular, even if it "may not be great economics".
"That is about the only thing that will get [students] out of bed before 7 o'clock at night to vote, but it's not politically sustainable to put interest back on student loans. It may not be great economics, but it's great politics.
"It is a bit of a tragedy because it sends the wrong message to young people, it tells them to go out and borrow debt."
