I think it probably is a planned detail but, while I'd like to think the best of them, it's most likely the more prosaic reason that they weren't drinking their sponsors product (Steinlager) but instead that of the tournament sponsor (Heineken) as required by the tournament rules.
The Stadiums Strategy is currently being consulted on as part of the Annual Plan process I think: Auckland Stadiums Strategy-Public Consultation.
Although given the link to the consultation documents doesn't seem to have any of said documents (at least not clearly labelled) it's not the best consultation ever conducted.
I note that the page Luther linked to links to this but thought I'd highlight it as these guys are always really interesting and usually quite balanced in their articles: http://www.sportsscientists.com/2012/08/womens-800m-analysing-semenya-other.html
They also touch on Ye Shiwen in some of their previous articles as well as one of the other main talking points of the games (from a scientific/performance point of view), Oscar Pistorius.
Haha thanks Chris but unfortunately it looks like it's up to one now - maybe it was while I could still edit it. Hopefully be able to get involved a bit more once I'm back in NZ later this year.
While trying not to sound like I'm rubbing it in, I have to say that in the UK you can get brilliant (free) coverage.
Obviously encouraged (or probably required to justify the cost) by the fact that it's a home games the BBC is showing all sports live. While they have only two tv channels at any one time, by 'pressing the red button' on the digital remote you can select any of the events that are currently underway.
The British commentators though do leave a bit to be desired, a bit less TeamGB cheerleading and a bit more technical explanation about where someone is good or bad wouldn't go amiss. But then again that's probably to be expected.
