Typically, New Zealand allows dependents of international students to accompany them and stay in the country while they study. This is usually covered under the "student dependent visa" category. Dependents may include spouses, partners, and dependent children.
The eligibility criteria, application process, and requirements for such visas may vary based on factors such as the primary applicant's visa type, the relationship between the primary applicant and the dependent, financial support, and health insurance.
To obtain the most accurate and up-to-date information, it's advisable to visit the official Immigration New Zealand website or contact a licensed immigration advisor familiar with current policies and procedures.
