Waiting for a job offer in New Zealand

Hi there. My DOB - 13 June 1980, female originally from Malaysia but currently residing in Auckland, New Zealand. I have been in Auckland since mid Dec 2013 and have been actively looking for job offers. I have been attending some interviews but with no success. I am looking for marketing opportunity in wine industry of NZ but I would not resist any opportunity in fast moving consumer goods industry. I wonder how long will it take me to get my desired job offer? And if the career prospects in New Zealand are looking good for me? I am dying to know as I do see my confidence level going down by day. Thanks.
