I've been out here 4 months, have a job and live in Wellington. It's certainly different to the UK and there's some epic riding minutes from the city centre (and further afield) but it's not all fjords and lakes n stuff. You still have to have a day job, go shopping, pay bills and put up with the same everday stuff you would back home.
Also a lot of the amazing scenery is miles away from the centres of population where you'll likely to find work. Don't get me wrong though Wellington is a shed load better than my home town of Merthyr Tydfil. Just come out here eyes open. Culturally things are a bit 'behind' (not as many bands visit, that kinda thing) and the work ethic is a bit challenging, certainly working in IT it's not exactly cutting edge stuff.
I don't mean to come across as negative, I'm loving it here and will be visiting the UK next week for a wedding so it'll be interesting to see whether my feelings are confirmed or if I miss greggs pasties too much and want to stay.
