I thought it worth sharing that I have done an analysis of the new INZ fees that come into force on 7 December. While most of the fees have increased, the change to the new way of charging for the Migrant Levy means that some people will be better off. For example, a single person applying for residence through SMC after 7 December would face a total increase of 17%. However, a family of four, would be better off by 19%. In case you have not seen the details, the Migrant Levy will now be charged per application, not per person. It will be $580 for SMC residence visas but only $280 for partner and parent category residence. It will be payable when you lodge the application, NOT when the application is approved in principle.
From the same date, Migrant Levies will also be charged on Temporary Visa applications ranging from $14 per student application to $38 for Work Visas, but there is a small decrease in fee for online applications, which keeps the increase quite small in most cases.
