Yes, medical insurance is compulsory for all international students studying in New Zealand.

Key points:
- You must have approved medical and travel insurance for the entire duration of your stay while holding a student visa.
- Most universities and institutes offer their own recommended insurance plans, or you can choose a private insurer, but it must meet the minimum requirements set by the New Zealand government.
- You will usually be asked to provide proof of insurance when you enroll and when you apply for your visa.

Why is it required?
- International students are not eligible for publicly funded healthcare in New Zealand (except in some cases of accidental injury covered by ACC).
- Medical care can be very expensive without insurance.

What does it typically cover?
- Doctor visits, hospital care, prescriptions
- Emergency medical evacuation
- Repatriation
- Some plans also cover travel-related risks (loss of baggage, etc.)
