Spyware: Why would HD feed come from SBS Australia - I'm gobsmacked if it does???, most likely feed comes directly from SA at 45 Mbps 1080i over fibre. The broadcaster then does what they wish. TVNZ broadcast 720p at 8 Mbps on DVB-T H.264 which is low bitrate obviously. I doubt if the DVB-S2 H.264 TV1 transmission is any different though.
Yes it;s strange but check out these sources:
