Im not sure what its like to live and work there, I dont know anyone who does. But its a really beautiful area, and there is a lot of tourism. I know that living and working in the areas close to there like Te Anau and Queenstown is a lot of fun. A lot of people working around there are from outside of New Zealand, so there is a lot of variety, and you meet heaps of interesting people.
All of the mountains in new Zealand are fold mountains, they were formed by collion zone plate boundaries that make the land buckle up over millions of years to form the spectacular mountains. I am sure it would be amazing to work there and be part of such amazing nature
thank you this helps alot :)
