John Gerritsen investigates the rise in overseas student numbers and the opportunities and risks.
International student numbers are rising again and nearly 100,000 foreign students are expected to study in New Zealand this year.
With annual spending approaching $3 billion a year, the students are good news for the economy.
But some warn there is trouble ahead because enrolments are growing too fast.
Radio New Zealand's Education Correspondent, John Gerritsen, investigates what is driving the growth, the risks it poses, and the blurring lines between education and immigration.

Radio NZ International's Johnny Blades looks at what's driving China's foray into the Pacific and what it means for the people of the region, New Zealand, Australia and others with long term connections in this part of the world.
8:12 am Sunday 5 April: Insight: Demands for Elective Surgery

More than 165 thousand New Zealanders had non-urgent or elective surgery last year -- 60 per cent more than in 2003.
They were the ones who got through the complex and poorly understood system for choosing which patients are most in need of non-acute hip or knee replacement surgery, or treatment for hernias, varicose veins or cataracts.
Many others failed to make it onto public hospital waiting lists for surgery but were returned to the care of their family doctor to wait and hope for a better outcome in six months' time, or later.
No one knows how big this group representing so-called unmet need is, but surgeons say it's rising as the population grows and ages.
Radio New Zealand's Health Correspondent, Karen Brown, has been exploring what, if any, changes are needed.
