I went in January 2012 and I thought this was a nice time, the weather was pleasant so not bundled up with jackets etc, but not to hot, so that was fine for all the walking around etc. the only time I needed a Fleece and jacket was on top of a snow covered mountain the franz. Joseph after landing by helicopter.
I did not find the tourist attractions that overcrowded either.
I went on the Hong Kong - New Zealand tour great sights to see.
