In New Zealand, if an employer wishes to hire a migrant worker and sponsor their work visa, they are required to undergo an employer accreditation process before being eligible to employ immigrant workers. This represents a new accreditation system, and even if you have previously obtained employer accreditation under the old system, you will still need to apply for the new accreditation. The specific type of accreditation required may vary depending on your business model and, in some cases, the number of immigrants you intend to employ.
