you are spot on with the clothes, just stuff you can layer on or take off!!!..I am not a great walker as in striding out and I managed just fine, more strolling than pounding the beat. Just take enough clothes for 10 days there are washing machines along the way, just make sure yours is in a bag to rush to the machines first as other people will have the same idea. Evening wear was really just smart casual for the evenings, some days are really full on so it's a bite to eat and go to bed. I booked the tours when I was out there, most of the flights you have to pay direct to the people who are running them. I do remember we did have an extra wine tasting tour which was VERY enjoyable! And worth doing, and also an Antarctic adventure www.iceberg.co.nz these were what our tour manager put in place.Do go and visit Sky-tower in Auckland this I did this away from the group www.skytower.co.nz well worth doing and just a stroll from the hotel we were in. If your going via Hong Kong the trip to Lantau Island is very good.
I am sure I did most of what was on offer. I was hoping to do many more helicopter light plane flights but due to the weather, they were not flying I only managed the helicopter to the Franz Joseph..you do get off up the top and when I went lots of snow so you will need jacket and sturdy shoes for that.
We had perfect weather for the visit to Milford Sound, I found this breath taking....
You will have a great time...
f you have any more questions just ask.
