"Student visa holders are the most affected group in migrant worker exploitation," said national co-ordinator Dennis Maga.

Mr Joyce said the amendments to rules relating to international students working will bring New Zealand in line with similar countries such as Australia.
Immigration no longer issues visas to students wanting to enrol with providers given a category four rating, the lowest status, by the New Zealand Qualifications Authority.
Last week, St George Institute of Learning in Auckland became the fifth private training establishment to be shut down by the New Zealand Qualifications Authority, along with at least 38 other institutions that faced "voluntary" closures since January.
