This story was around weeks ago, in Niue anyway, so it's not an April Fool. Niue is self-governing, but NZ does a lot of stuff for it, rather in the way France handles foreign affairs etc for Monaco, and it seems this includes designing stamps. In spite of the self-interested comments from the Stanley Gibbons wallah, stamps are produced primarily for the convenience of people sending mail, not for collectors, but it looks as though this will have more appeal than usual to people with stamp books. I don't expect any heads to roll at all.
