No, it's not all right. Your two applications are among THOUSANDS proceeding through the workings of a huge government bureaucracy - they're not side by side in a two-horse race. There is not just ONE system within INZ. So (annoyingly for you, admittedly) the fact that there has apparently been some hitch in the system your case followed, which there wasn't for your colleague, is by no means a sign of unfair operation. Besides all that, making an application for a visa is a REQUEST to a foreign government for favourable consideration, and no kind of right.
