All imported beef and lamb will now carry a label notifying Kiwi consumers of the product's country of origin.
While most beef and lamb for sale in New Zealand is produced by local farmers, a very small amount comes from Australia.
A change which comes into effect today means most retailers will voluntarily label any meat from across the Tasman as 'Product of Australia'.
Rod Slater, head of Beef + Lamb New Zealand, said the move was instigated by meat retailers around the country.
"It was a unanimous decision by Quality Mark retailers to support country of origin labelling and it shows how proud we are of the product we produce."
