New Zealand companies linking with China

In yesterday's Dominion Post there was a snippet about a Marlborough company called Aquaflow Bionomic Corporation which has teamed up with Chinese company Greenleaf Environmental of Sichuan.   The two companies are investgating sites in China for the Blenheim (New Zealand) based company's fuel-from-algae technology.  Aquaflow think they are the first environmentally focused company to move into that region of China.
In 2008 Rakon established a joint venture with Shenzhen, China company Timemaker Crystal Technology.  How many other New Zealand companies are working in collaborative ventures like these?  Does anyone know of a directory or list of such companies?  If so it would be really useful to be able to publicise such  a resource, as it may help companies thinking about expansion to China to contact experienced New Zealand business people and avoid mistakes and get tips.
