He also supported suggestions honey should be tested before it was allowed into a country.
"There's so many rednecks in the industry ... I've heard of guys blending other honey with manuka," he said.
"The industry is too fragmented so no one seems too interested in doing anything."
There also needed to be more definition about the terms used to label the products, he said.
Some of the companies selling mis-labelled honey are New Zealand producers and some are foreign. But even the most reputable New Zealand honey producers now face heightened surveillance in the UK.
Paengoroa-based company Comvita, New Zealand's biggest manuka honey producer with a market capitalisation of nearly $150 million, is demanding the industry be cleared of cowboys.
Chief operating officer Scott Coulter said pots of manuka honey labelled with meaningless numbers and certifications were designed to confuse customers who thought they were getting UMF accredited food and nutriceuticals with measurable health benefits.
"You can put a number on any honey, and that is damaging to Comvita," Coulter said. "They can buy a 20+ honey thinking it is manuka and it is not. "
