If I wanted to move into your country in a few years time.... what do I need to have? (money, skills etc)
Go to NZ Immigration and Naturalisation online. Assuming you mean a perminant move you get points for things the country wants i.e. ibeing under 30, having a degree, having skills, having a job lined up. Then you can see whether you have enough points or hoe to get them. If you are young and from a friendly nation it is failry easy to get a short term work or study visa just to come over and check things out.
