well Ali if your oh future employer says he dont need registation then its a safe bet he dont ,would they, or do you have anything in writing to say that.if so buzz that off to NZ house.
Theres a good chance the electrical work may be signed off by one person for the whole company and that man could be the only one needing to register ,this seems to happen in for example lift companys.
Good luck hope all goes smooth for you
