Do it. Do it now. Don't stop to think about it and don't come home after six months.
I went in 1986 and learned to skydive at Pudding Hill. I spent six weeks going all over and had the time of my life. It's a beautiful country and very welcoming too. In some ways, it was like being in the England of the alternate universe because lots of things were quite familiar, and lots of things were different. For instance, I saw all these cars that had long ago disappeared from the English roads. Like the Triumph Dolomites, Triumph Heralds, Rover 2000, Hillman Minx Ford Zodiac. Quite interesting. Apparently NZ has every single geographic region from Desert to rainforest, Geo thermal springs to Alpine mountain.
I'm going back someday.
Oh and another thing, when you say "spend a Summer" there, I guess you mean Winter
