Tangawizi; not sure, is the short answer. Last year they showed most rugby games live (that's from word of mouth - a friend had it). I have no idea how they will go with it this year. Check before you consider it....or read below, as I just spent 10 minutes looking at the first week.

For the first week, both Friday rugby games are on delay, first being at 10pm, due to the A-League. Most of the games are shown, including replays the next day.
For some reason, the Reds vs Tahs game is not scheduled at all on Saturday or Sunday! In fact, it is first shown at 7:00 am Monday morning. Obviously Chamionship football is more important, as that is shown after the A-League triple header on Saturday. What the fuck? The Reds had some of the biggest audiences last year on Foxtel, and they aren't even bothering to show the Tahs vs Reds at a normal time. What idiots in the scheduling department thought that up? And there appears to be no extra rugby channel.
I guess that rugby will only be live once the A-League finishes this year. How lame.
