Just spend about an hour watching the shakedown in the domain, the super special stage is going to be awesome. They've made a pretty sweet track, and the cars are pretty loose on the gravel tyres! I made a quick map of the circuit for the benefit of those intending to go (since I couldn't find anything decent on the Rally NZ website).
Heaps of good spots to watch, the corner leading on to the Crescent is pretty sweet (coming downhill at speed into a very sharp right hander), and the temporary chicane going from the crescent to lower domain drive will be pretty awesome when they're really pushing (I'm predicting at least one crash on the exit of the second corner), the right hander on lower domain drive before the left hander into lovers lane is pretty good too, and the run up lovers lane is very narrow and twisty. Even the first left hander after the start looks pretty good.
