Allegations of cheating at universities and other tertiary institutions have prompted 22 complaints to government agencies in the past month.
The complaints follow Tertiary Education Union warnings that lecturers are under increasing pressure to pass students.
The Tertiary Education Commission said it had received 17 complaints in the month since union members warned that institutions were lowering standards in order to pass students who should be failed.
It said it was working on seven of those cases and the remaining 10 required no further action or would be resolved by other agencies.
The Qualifications Authority said it had received nine complaints in the same period, four of which came to it from the Tertiary Education Commission.
The authority said one of the complaints had been referred to Universities New Zealand and it would not comment on the remaining eight.
