My favourite place to go to in the south island is Christchurch. Those aftershocks seem to be slowing down so it seems safe to go there. The three best places to go to in Christchurch are the International Antarctic Centre, the Royal New Zealand Air Force Museum and the Christchurch Art Gallery. My favorite place out of these three is the Royal New Zealand Air Force Museum you can fly a mosquito bomber simulator, go on a tour of a ww2 air base complete with aircraft hanger accommodation for ww2 aircraft crew. Here is a link to the to the Air Force Museum,the International Antarctic Center and the Art Gallery.
