I made the climb in August, though not at dawn, as part of a protracted antipodal trip with many ascents (see under "HPs this year" thread, or similar). It was enjoyable enough though expensive and as you report, there was an awful lot of rigmarole. Cameras must even be left behind, lest one be dropped on peds, bike riders or traffic I suppose. (you get a copy of a group photo from the crest). With typical cynicism, locals call it "the coathanger"!
