All exports of New Zealand manuka honey will have to be tested as authentic against a new definition set by the Ministry of Primary Industries before it can be exported.
Agriculture Minister Damien O'Connor said the testing regime was set up to safeguard the industry from cowboy operators and to protect New Zealand's trade reputation.
He said MPI had recently filed charges against a company and two people alleging offences in relations to the adulteration of honey.
"The definition will help stop that kind of activity, which undermines our reputation across the whole food chain.
"If we didn't introduce this standard, then other countries may have forced one on us."
