Work visa

Hello every one. My name is Nick .I was doing research on NZ and found your details online and wondered if you would be able to help me with some guidance. I am Greek living in Greece but really really  really want to move to NZ, i am a plumber and my job is on the skills shortage list but i am 35 points off applying for my visa unless im able to find employment before i apply for my visa. Do you know of any plumbing/construction companies that employ overseas or where i can find a good recruitment agency that employ overseas workers? The economy is so bad here now so any information you can give which will help me leave faster will be greatly appreciated.

Kind Regards
Nikos Doukas
