Hi,
I'm sorry, things are a bit rushed around here at the moment.
So speed typing !

You could check out these links for software companies in NZ.

These are a small selection of a number I've collected. See the New Zealand part of my website. The links page of that. Then 'Directories'.

Canterbury Employers' Chamber of Commerce - Members Directory

Canterbury Software

NZS ? Computers ? Software

Pipers ? NZ Software Development companies
http://www.piperpat.co.nz/nz/software/develop.html

Pipers have changed their website, so you may have to find the equivalent place.

I hope that helps.
Hope to chat better later.
