The tuition costs could be quite expensive at times, for some international students. An exception is if an international student is enrolled in a PhD programme in a recognised institution in New Zealand, then he/she pays the domestic tuition fees.
Arts and science courses could cost anywhere between NZD 20,000 and 25,000 per year. An undergraduate programme can cost between NZD 18,000 and 25,000, and a postgraduate programme can cost between NZD 10,000 and 30,000. You should also factor in your living expenses and transport cost. The student health cover is a must, and it may cost you more if not taken from a recognised provider.
