Fixed term

Fixed terms are supposed to be used for situations where funding for the role is limited to a certain amount or duration. Sometimes there is a strong case for someone to be made permanent if the employer is simply trying to keep their staff on a more casual basis. You could approach your company about this, and if that doesn't try mediation.

If there is still no resolution, if you had a good case you can go to the Employment Relations Authority. www.era.govt.nz/
If you need additional support, unions can be a great help.
