Your 2010 link was a one off and a final I think ... http://www.throng.co.nz/2010/03/tv-ratings-7-march-2010/
There is a weekly crowd and ratings thread ... has been running weekly for Hal's 8 & 9 to date ... http://www.yellowfever.co.nz/categories/news-discussion-and-football-blogging/topics/attendances-2012-13-season
If you can get the rating please please post them... it's not like they have not been requested or it is a thread with no one reading...
The Phoenix have been playing on Sky Sports 4 which doesn't seem to be tracked.
Regardless a market of over 4 million isn't something to be sneezed over, that's 20% of the domestic Australian market, unlike Rugby League the NZ public didn't have much exposure to Australian football before there were NZ teams in the market so I would imagine the ratings would be abysmal without the Phoenix.
The main problem we have is that there is a sea in the way and therefore we don't have many away fans to boost our attendance, and vice versa when we travel. Things would be improved both with attendance and TV if there was another NZ team so that we could have a local derby and competition between fans.
