If you are considering a helicopter flight while on the South Island of New Zealand be sure to check out Glacier Country Scenic Flights located alongside of the Whataroa River. It was the best thing we did. We took the Mount Cook Panorama flight that takes you up the Middle Earth route from Lord of The Rings. Then we climbed and climbed some more until you are seeing the Southern Alps eastern slopes. We then did several passes around Mt. Tasman, and Mt. Cook, and then passed back to the west coast for views of Fox and Franz Josef Glaciers. It's a very low key operation with a friendly competent pilot that gives you a narrative as you fly along. I don't think you will be disappointed.
