We had a fantastic time in New Zealand and yes I did do the Canyon Swing - Here is proof! Yes that is me, after a lot of coaxing that I really could throw myself off a cliff! The actual step off was scary but once you were swinging around the canyon it was fine.
New Zealand has so much to offer and is so incredibly diverse. The scenery can and did take your breath away. From the moment we left our house to the moment we got to my brother-in-laws house was 23 hours and the kids did surprisingly great. Although can I just say it is a little disturbing when the airline staff bring you the child life vests and say "just in case we go down in the water". Not a great thought as you are about to take off on the runway.
There is so much to do and see in NZ, we cruised through fjords, climbed glaciers, strolled through rainforest, played in oceans, jet boated through river canyons, luged down mountains amongst many other things. The country is vast and uncrowded, amazingly uncrowded and a big proportion of their income is from tourists.
For me personally it was like going back to the UK 30 years ago. (Apart from the amazing scenery), there was so many things there that was British, old British cars, even the playgrounds had equipment that I remember playing with and on when I was young. So on that note I am leaving you with my favorite memory of NZ.
