interesting to note that North Harbour Stadium has gone from hosting the All Whites to hosting an ITM Cup game in the space of 16 hours...
Am I imagining that I saw them rubbing out the lines straight after the game? I think I did, but surely the lines can be simply brushed away! Perhaps I had too many beers.
It's not quite as simple as that. One thing you might notice about Rugby games is that they have rather cumbersome advertisements painted all over the pitch. They take more time and effort to brush away, as the advertising wouldn't be permitted for A-League broadcast. Then it would need to be painted straight back on for the next RWC match.
Another factor is the damage done to the pitch. Rugby does a lot more damage to the pitch than football does, obviously. Also, rugby can be played on a crap surface without much consequence to the quality of play (i.e making it easier at NHS to host an ITM cup game straight after the AW match). Football does not have that luxury. Pitches would need to be rolled, all divets replaced etc etc.
I'm no expert in ground management by any means, and there's probably a whole lot that I'm missing out, but the exchange of a rugby field to a football pitch is no mean feat.
