Immigration New Zealand will be asked to tighten controls and checks on international students and their agents at a seminar in Auckland today.
About 116,600 applied for student visas in the year to June with more than 99,000 approved to study here.
Over the period 912 student visa holders were declined a further student visa, with India topping the list on 209 declines followed by China with 205 and Fiji with 92.
Immigration New Zealand said the students were declined because they cannot prove they are bona fide students. Reasons for rejection included being unable to prove a genuine intention towards their stay or study plans, and failure to show they had access to enough money to support their study plans.
June Ranson, New Zealand Association for Migration and Investment (NZAMI) chairwoman, said the student visa was seen as an easy pathway to gain permanent residence.
