I’ll echo pretty much all of what’s been previously said but if you have never been to NZ, it would be far better to go for trip and experience the country.
It is an outstanding place in many ways but it does have its bad points and the life is not for everyone.
If its money your going for, NZ is definitely not the place to go.
It is getting much harder to get in (for truckies anyway) but persevere, particularly with accredited companies.
You can do the visa process yourself, it is relatively straight forward, but if you have any doubts or children are involved (especially with a WTR visa) I would suggest enlisting the assistance of an immigration advisor (INZ registered), (I can recommend a company if needs be). It does cost a bit but will ensure every I is dotted and T is crossed and everything is done in the right time frame.
