A private tertiary school in Auckland has been told to stop enrolling students amid doubts about its courses.
The New Zealand Qualifications Authority (NZQA) has ordered the temporary halt at the International College of New Zealand (ICNZ).
NZQA said it had looked at how the college was assessing students in its Level 7 Diploma in Business Management, and had concerns about its validity.
It had already raised concerns with the school about its Level 5 and Level 6 business diplomas.
The compliance notice also put a stop to any reporting of students' results in the business programmes while more checks were carried out.
ICNZ head Chirag Solanki was unavailable for comment.
