The fact is the sponsors want games in Auckland and this year was an unusual situation because the stadium was closed for a long period of time. As said above it's the busiest stadium in the country, and even though the Phoenix are the number one tennant they do not seem to get priority.
Most years we will loose two games which is a necessary evil and probably a good thing to do now that the A-League is in expansion mode and there's the possibility of an Auckland team in several years. The only real solution to not loosing games to events like the cricket world cup and maintenance that is not favorable to the Phoenix is to get a second smaller stadium for the region, not going to happen in the medium term - so the Phoenix needs to try and flex their muscles with the stadium trust by being the biggest tenant.
@Kiwi Hatter as part of our negotiations with the FFA we asked to be able to negotiate the NZ tv rights.
