Europeans, Americans and Japanese will love Queentown, NZ...well maybe you will hate the fact that there are already a lot of you already here. Its enough to ruin a place. :)
The good news is that you have a good reason to come to the land of 'milk and honey'.....your currencies are being debased faster than you can say 'Holy cow'. This is just one appealing aspect about NZ. It is a relatively hard currency.....and whilst income growth here is sluggish, that will change in i'd say around 5-10 years for a number of reasons related to resource development, but also its services-related potential. Yes, NZ is going to find a place in the business outsourcing arena, though it will have to improve its accent and telephony infrastructure. In the meantime, expect a currency gap to widen with Australia.
NZ does appeal. The population is flat...but that will change. This is why I think buying in 3-5 years time makes a lot of sense. All the better if you can debt leverage the property and perhaps spend your 'quiet' summers near before you retire here. Why? Well, summer is quiet here. You just have to decide if you like winter here. Given you are coming from Europe, Japan or the USA, you will struggle less with that question that if you are coming from Australia.
In 10 years, I think NZ's fortunes will turn around. I expect some major resource developments which are going to see a major change in the terms of trade, business investment, population retention, and currency ascension. Yep, and some government will take all the credit...when it was all me. Yes me. I was the one who pulled the lever first. I'm holding the smoking gun!
