Hi,
If you want to find a company by what it does, try one the directories.
eg
Pipers NZ
http://www.piperpat.co.nz/nz/
Product Finder - Find companies by name, brand or product type
Another directory that you can use to find jobs
http://www.productfinder.co.nz/index.jsp
If you know part of the company name, try:
New Zealand companies Office ? A searchable database of all registered NZ companies
If you enter the ?Search the Register? and ?Register Search?, you can enter even part of a company name
and find out it's full name, address and names of the directors. Could be useful !

I've got others listed on my NZ links page.
