I seem to recall it's a 7-8 hour flight from Christchurch (haven't done it myself, but I think that's what I read). The cargo planes they take are impressive! Of course, there are no flights at the moment--they can't land in the dark down there, and the sun won't rise until late September. It's always in the papers, the first and last flights of the year--always a few words about the movies or other treats they're taking down to see them through the winter.
