Hi Elizabeth,
to MoveToNZ.
This is a site dedicated to
waste management in NZ . There is a page for jobs but there doesn't seem to be any listed at the moment. Nevertheless, perhaps you could contact them to see if they can offer you anything or suggest something to you.
If you have a look on the
NZ Website List under Employment, there's quite a few job sites listed. Don't take too much notice of the job type that comes after the links as most of the sites deal with all manner of jobs.
Alternatively, if you don't mind paying for someone to help find a job, you could contact
New Life NZ as your job type isn't that run-of-the-mill.
