Skills in demand
Some skills are in chronically short supply, and Immigration New Zealand has lists of skill shortages.
If you are offered a job in New Zealand which appears on a skill shortage list and you have the qualifications and experience to match, getting a work and residence visa will be easier. This is because the Government has identified that employers need to recruit people from overseas to help meet demand for your skills.
Currently, the lists cover skills in these areas:
Long Term shortages Immediate shortages Canterbury shortages
Agriculture and forestry
Construction
Education
Engineering
Finance/business
Health and social services
ICT and electronics
Oil and gas
Recreation, hospitality & tourism
Science
Telecommunications
Trades
Transport
