The New Zealand meat industry hopes China will continue a crack-down on food scams.
In the past week, Chinese officials have detained 900 people for meat-related crimes, including selling rat and fox meat mixed with chemicals as fake beef and mutton.
In Shanghai, food safety officials are testing meat seized from a wholesale market that appear to have been mislabelled as New Zealand mutton.
The fake labelling issue is a long running one for New Zealand food producers, with products ranging from apples to mussels being found over the years carrying false New Zealand labels.
With demand for New Zealand meat surging in China, Meat Industry Association chief executive Tim Ritchie said mislabelling scams are likely to continue.
