Well Christine,
I have not been in New Caledonia yet, but it is my dream. In my opinion, a person that wants to move in a Country where the language, culture, uses are different from its own, should have a really open mind, an adaptation ability and the will to face a new reality as well. Everything to say that I do not consider it as a shock, but I could say that it is an exciting experience.
Anyway this changes person by person, and if anyone has already lived there, we are glad to receive any feedback from them.
Have a nice day (or night) to you all!
Andrea
