交一份180申请费就可以了。如果之前的移民申请,家人是和你在一个申请里面的,就可以放在一个申请里面。请参考移民局的原文:
Who can be included in my permanent resident visa application?
In most cases you can include your partner and children in your application for a permanent resident visa (or further travel conditions) if they were included in your original resident visa application.
To be included in your application your partner and children must have at least been in New Zealand as a resident.
All those applying can be included on one form (INZ 1175) and only one fee is required.
One common exception is that if your children are now 25 or older they must make their own application and pay a separate fee when applying for a permanent resident visa or further travel conditions on their resident visas.
