In an effort to resolve the issue of exploitation, Immigration Minister Iain Lees-Galloway proposed removing the requirement for post-study work visas to be sponsored by a particular employer. This will also limit the length of post-study work visas for courses below degree level to one year and remove the post-study work rights for the courses of length that is less than two years of duration. Graduates have option to apply for other visa at the end of their post-study work visa but they need to meet the skills and labour market tests. Concerns raised that under the plan to limit post-study work rights, the number of students coming to New Zealand each year may decline up to 44,000 which will cost the economy more than $ 1 billion a year. The proposals are revised after 2000 submissions were received. They believed many students would look at their options in other countries if their post study work rights were removed in New Zealand.
