These types of visa allow you to be in New Zealand, until the date specified in the visa, for any legal purpose, such as visiting family or friends, getting medical treatment, or just sightseeing. You must establish that you are a genuine visitor. You cannot work or study, apart from one course of study or training of up to three months. The maximum time Immigration NZ may grant a single Visitor Visa for is 12 months, and usually one won’t be granted for more than nine months.
