Twelve foreign nationals who have applied to study or work here are under investigation over fears that they're coming here to make weapons of mass destruction (WMD), Newshub reported.
These international students, who are being investigated by Immigration New Zealand, are from countries that have not signed Nuclear Proliferation Treaties or have access to WMDs.
Seven students were denied visas over concerns their study could contribute to a WMD programme.
All 12 are from nations that have not signed special treaties which aim to prevent the spread of nuclear weapons, such as India, Pakistan, Israel and South Sudan.
But they could have also come from countries that have WMDs or WMD programmes like North Korea, China, France, Russia, the UK and the US.
