This has been one of the most popular questions,
There are no plans at this stage to broadcast in HD via the satellite platform. This is due to bandwidth limitations and cost - HD requires a much larger amount of bandwidth and SKY TV has leased the majority of the suitable bandwidth on the Optus D1 satellite so there is not enough room for Freeview broadcasters to transmit HD.
If, in future years, Freeview broadcasters did manage to secure additional bandwidth, some viewers would need to replace their current satellite receiver with one that is capable of decoding an HD signal. Freeview in HD is available to 86% of NZ homes through the Freeview via UHF platform.
