You should apply for a work visa in New Zealand well in advance before your studies end. A popular option is the Post-Study Work Visa (open or employer-assisted), which allows you to work in NZ after graduation. Apply within three months of completing your program. Make sure to meet all eligibility requirements, including having a recognized qualification and a job offer if applicable. Starting the application process early ensures a smooth transition from student to work status, giving you ample time to secure employment and extend your stay if desired.
