The loosening of China's one-child policy is expected to provide a boost for New Zealand infant formula exporters, many of whom are still being hit by the residual impact of Fonterra's botulism botch-up.
The country's Communist Party has announced Chinese couples will be allowed to have two children if one of the parents is an only child.
At present, both parents must be only children in order to be exempt from the one-child rule.
The change will allow millions of Chinese parents to have a second child, and the announcement prompted share price gains for companies with baby-related products.
Shares in Hong Kong-listed Yashili, the Chinese dairy firm establishing an infant formula firm south of Auckland, rose almost 10 per cent on the news.
