Can anyone help the clarify something for me pls? I've been looking at the Priority Occupations list which in itself is clear enough but where it states 'Qualified' it doesn't state what level or type of qualification is needed. A good example of this is Bulb Horticulturist - Qualified. I've had a good look in the NZQA site but that particular occupation isn't listed. So how do you know what qualification is applicable? Or at what level?
can anyone shed some light???
Thanks Smokey.
