Siberia Valley
Almost five years ago, My son Tim took us on a tramp into a very remote place in the Mt Aspiring National Park, the Siberia Valley. He was really looking after his aged parents: had a sat phone in case of emergencies, was continually telling us what the weather was about to do, and in general was completely in charge. (Actually, the reversal in roles felt very good indeed!)
The valley itself is a great place, accessible very quickly via helicopter (but a couple of days walking otherwise).
