I'm not seeing it. As a New Zealander, I'm probably too accustomed to black and white to make that link. Also, I think the angular-ness of emblems is what makes them feel fascist and the silver fern is too curved to qualify. At worst, this looks like an All Blacks rebranding. Still, this is a site about alternate history so maybe the connotation of an alternate fascist New Zealand is what appealed to the users?
