If you would like to live and work in New Zealand permanently, you will need to obtain a visa or work permit. You can learn more about whether you qualify for one of these at Immigration New Zealand .
Immigration New Zealand also grants temporary work visas and permits to people who have a job offer from a New Zealand employer, people skilled in occupations that are in demand, people going to the country for a particular purpose or event, people who want to gain work experience or people who want to work after studying in New Zealand.
If you're aged between 18 and 30 years, you may be eligible to get a temporary work permit for a working holiday. You may also be granted one if you plan to work in the horticulture and viticulture industries.
If you're already in New Zealand as a visitor, you can take a single course of study that lasts less than three months without requiring a student permit. If you want to take more than one course and/or study for longer than three months, you can apply for a student permit while you are there.
For those outside New Zealand and planing to study full time for more than three months, you will need a student visa and a student permit, unless your home country has a special agreement with New Zealand. If you're a full-time student, you can work up to 20 hours a week during the academic year as well as during the Christmas holidays. On completing your course, there is a Study to Work visa category if you wish to remain and work in the country.
