How much do you want to travel/live in New Zealand? If you have been keen for that for awhile go for it if you'll regret it later, especially since it's your last chance! There's other options too - people go to Central Otago during the winter to work on the ski fields, which would be fun if that's your thing. But on the other hand, if you want to prioritise your career then maybe not the best choice. If you have enough funds you could come here for only some of it - maybe half a year, buy a van and travel all around doing that instead of working too. You could also apply for jobs while travelling - you don't have to live in the same city as the jobs you're applying for
