New Zealand is awesome, you won't regret the choice.
Well, mostly anyway.. Though be sure about any waterways you wish to swim in, reports today indicate that our government has decided to end pollution by re-defining what is classed as "pollution" (disclaimer : haven't yet got around to looking at it in depth, just a few little bits on the radio as I've been out and about today).
I do however welcome you, and hope you enjoy your stay. You'll find most of the people welcoming, the beer horribly cold, not sure how you'd rate the food, the tap water wonderfully clean, and the scenery (often) beyond words. Just take note of anywhere you want to swim.
