Hello.
Here is another thread where the original poster had the same question.

I know this situation seems harsh to many people, but it aríses from a fairly recent change in the law, which was from good motives. Before, the partner and family used to be allowed to go along with a JSV holder, but then, if s/he didn't get a job, it was a very bad situation for them if they had settled into a new home and school in NZ, but had to pack up and leave, specially as they may have sold their old home and the partner may have given up a job back in their original country. So now, INZ says from the start that the JSV is expected to go on ahead and concentrate all their resources on getting a job offer, and only then bring the family in.
