If you immigrate to New Zealand to be a plumber! Do you need any conditions? Is it a shortage industry?

Gardening, nursing, social workers, engineers, preschool education, hotel management, western chefs, crew and so on in New Zealand are in short supply. It's easy to find a job when there is a shortage of majors. You can get a work visa if you find a job. It's just a little more difficult, such as nursing. IELTS requires four sevens, which is relatively high. Relatively speaking, marketing and other business requirements are relatively low.
