This weekend, a mothers and babies expo will be taking place in Shanghai, and among the thousand of exhibitors there will be representatives from New Zealand.
Those New Zealanders run export businesses, making a profit from sending New Zealand-made milk powder overseas, mainly to China.

Up until now we may have been under the impression it was family members who were buying the powder from supermarkets and sending it to relatives in China.
After emails from people in the area concerned about the large amount of baby formula arriving and leaving again, Campbell Live reporter Kate King went to check out what goes on at the address.
