An Auckland businessman is facing 13 charges for providing immigration advice without a licence or being exempt.
The Immigration Advisers Authority (IAA) has accused him of advising clients to mislead New Zealand authorities.
The man made an initial appearance in the North Shore District Court on 29 July and is due to reappear on 26 August.
The authority said immigration advisers must be licensed by them or be an exempt person, such as a New Zealand lawyer.
Andrew Galloway, registrar of the authority, said the case was an important reminder that people looking to immigrate should always use a licensed adviser.
"Licensed immigration advisers are required to be competent in their practice in immigration advice and are required to a follow a professional code of conduct relating to the advice they supply," he said.
People can check whether an adviser is authorised on the IAA website.
