How are you travelling? If you are independent the drive from Christchurch through the mountains over to the far coast for the Franz Josef is spectacular with plenty of places where you can stop to take photos. If you are on a fixed tour the bus will probably stop at the best spots.

In Queenstown if you have the time a trip to Wanaka and a boat cruise on the lake would be worthwhile, as would a trip to Milford Sound.

The scenery in New Zealand is such that you could stick the camera out the window almost anywhere and get a decent shot.
