Under the new process, if your migrant workers are paid over 200% of the median wage — that is, they have a high-paid job — they will be able to apply for residence after they have worked in New Zealand for 2 years.
There will be a new residence visa for some people holding the new temporary work visa. To apply for residence based on the new temporary work visa you will need to:
be paid over 200% of the median wage, and
have worked in New Zealand for 2 years.
As is the case for all work visa holders now, anyone on the new temporary work visa will be able to apply for other residence visas — for example, a Skilled Migrant Category Resident Visa — at any time while they hold their work visa.
