Auckland does not get THAT cold in winter. If it gets below 12oC they are moaning about the cold. Yes Auckland weather seems to rain a lot, but 5 minutes later its sunny again.
There are lots of inside things to do eg Kelly Tarltons underwater world. They have rainbows end which is a theme park in Auckland which is an option and do some of the rides. I went years ago and I am not sure what they have now but there will be some rides she could do.
I would do Auckland.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
