Hi Amanda,
My wife is a qualified Nursery Nurse (NNEB now know as CACHE) and has had her qualification pre-assessed by the NZQA (
http://www.nzqa.govt.nz/) as a level 5 qualification this gave her 50 points as the primary applicant.
You will need to have your own qualification assessed by the NZQA.
Cheers,
Chris.
