The New Zealand Government requires international students to be covered by an NMIT-approved current medical and travel insurance. As an international student on a student visa you are unlikely to be entitled to publicly funded health services and as such you may be liable for the full cost of and treatment.
NMIT will automatically arrange insurance coverage for all students. You can choose your own insurance company, however it must comply with the minimum standards required by the Code of Practice for the Pastoral Care of International Students.
The yearly costs for insurance is approximately NZD$650.00 (or $54 per calendar month).
