They are also learning from central London stadiums like Stamford Bridge and Craven Cottage (which have hotels etc in the complex to generate 24/7 revenue).The last few years there have been comments from Auckland Rugby who have an interest in Eden Park saying it isn't financially viable for them to use. That says a lot about that stadium.
A central city stadium will have similar challenges in terms of making the stadium viable. But a modern facility will be more appealing to spectators, the city should be better to get to and from via public transport, it will also be closer to restaurants and bars after matches or concerts.
- It won't be able to fund itself
- If the parties that have an interest in the Eden Park Trust don't find it viable. How is it going to be viable for other teams like the Warriors. When there was discussions on moving the Warriors it was stated the club would need to increase their average capacity. That isn't exactly a great incentive for a club to move. In Sydney to get the Olympic Stadium used they made it beneficial for the clubs.
A modern stadium configuration with the tiers being closed off for smaller events should also help with making it viable for the different codes. It would staffed for each configuration. They probably can do that for Eden Park to a certain extent but the tenants often complain about the extra staff needed when they use Eden Park.
Warriors, Blues, Auckland Rugby, Auckland FC, All Blacks, Kiwis, All Whites - there'd be a game every weekend too (plus concerts).
