Australia-New Zealand
It's "Australia-New Zealand" for the same reason foreigners always consider Canada part of the USA: we're too small a market for anyone to invest in caring that we are quite distinct. Such things are never intentional insults, no more than it is when we lump the British, French, German etc. communities together as “European” and treat them as one market, one community, one culture. (Though to be fair, the creation of the European Union to unify not only trade but harmonise laws amongst member nations does give a certain level of credibility to the concept that Europe is rapidly becoming a single culture by choice.)
Remember how smaller outfits like El Reg work, however. European operations for El Reg operate out of London; they have a central office there, however they have staff across the UK, in Spain and (IIRC) have at times had staffs in other European countries as well. This gives them a bit more of a pan-European presence without having to actually put an office (with the attendant costs and staff) in each country.
They have a separate US office because, well, the US is fripping huge, has Silicon Valley and is populated by a number of great hacks that churn out good pieces. Now that they have an Australian office, they may one day attach a NZ hack to that office, without actually maintaining a distinct office presence.
You should in fact be a little bit happy about this. When they talk about their Australian office, they talk about “Australia and New Zealand.” This at least acknowledges that you exist, that your market has value. It carries with it the implications that you are a separate culture (distinct from Australia,) that they will report on things that make matter to New Zealanders and potentially one day that you will have marketing targets at you that is indeed distinct from that which is targeted at Australians. (Isn’t it always fun to get ‘targeted advertisements’ for products and services that you really would like to be able to buy, but which aren’t even available to your country?)
In short: quit your bitching. It could be far worse; you could be Canadian. El Reg (like pretty much every other foreign organisation out there) doesn’t even acknowledge we exist. The US office of El Reg isn’t “US-Canada,” or “North America,” it’s “the US office.” There is no reporting on events that matter to Canadians, and no targeted marketing. Even the Irish (despite El Reg’s UK office being “UK” instead of “UK-Ireland” or “UK-and-Europe”) at least get the occasional article about Eircom doing something stupid. If I want to keep abreast of exactly how CIRA, the Telcos and the CRTC are conspiring to slap Canadians across the face with a rotting fish then I have to go to Ars Technica.
So please, no complaining. El Reg did not intend New Zealand any insult. Quite the opposite, I think. Local readership levels in New Zealand are high enough to have honour of actually existing in the eyes of Vulture Central. That’s kind of cool. Actually, not “kind of.” That’s really, really cool.
One day, I hope Canada makes it to that point. We don’t have a good Tech journal of our own. Ars is the closest there is, but they are American, they think like Americans, they write largely about things from an American perspective. Canada is still far more British than it is American, and I would much prefer to source my tech news here. (If only I could convince El Reg to get Michael Geist to write articles for Canada!)
So stand proud, New Zealand. Enjoy that you actually exist! Even if it is as part of “Australia-New Zealand.”
