Hi Beverley and Welcome to our Mad House
I can't help you much with the PR / Work Permit side of things, but I used to do secretarial work when I lived in Auckland. It was a few years ago now but I understand secretarial work in Auckland now pays on average NZD50,000 and EA (Executive Assistant) approximately NZD60,000, so I would think with your experience, you could easily expect to exceed your NZD30,000 and probably a bit more. Have you tried
this website for jobs?
Have you looked at the
NZ Immigration site? There's also contact details there - you could contact them if its not clear on the site what the requirements are for the work permit.
