Why Category B takes so long
Two of the four stages happen outside New Zealand. Your file leaves the country, waits in a queue at one mission, then waits again at another. Nobody in Wellington can hurry those queues, and we will not pretend that we can either.
That is not a reason to avoid Category B. It is a reason to start early. People who reach us six weeks before a deadline usually make it comfortably. People who reach us with ten days left often do not, and no service anywhere can change that. Couples registering an overseas wedding hit this most often, because the date is fixed long before the paperwork is — our marriage certificate translation page explains how that document is usually prepared.
A mistake worth avoiding
Some people lodge a Category A application for a Category B country and hope it slips through. It does not. The file comes back, the fee is gone, and weeks have passed for nothing. The category is set by the destination country, not by what anyone applies for — so if we tell you it is Category B, that is not us upselling you.
