The Government has ordered a range of checks on New Zealand's food assurance system, as the amount of infant formula exported rapidly grows.
Food Safety Minister Nikki Kaye has asked the Ministry for Primary Industries to audit the current regulatory regime to identify areas that need improving.
Infant formula exports are worth $600 million per year with $170 million of that going to China.
Overseas market access requirements will be examined to ensure they are keeping pace with changes to China's regulations for infant formula.
And there will also be an investigation into ways of better communicating with the Chinese market in areas such as science and labelling.
