Hey I'm from NZ & received a similar txt msg, not once but five times (see below). It looks like these guys are heading round the world, using different premium mobile numbers to call/txt their lottery hoax. I contacted my mobile service provider & they said not to call/reply to this sms. I also recommend you phone your mobile network so they can block these pricks from sending you more.
