The dumping of Italian processed tomatoes onto the New Zealand market has been found to have little impact, according to a Ministry of Economic Development report.
Heinz Watties, which sells canned tomatoes under the Watties and Oak brands, made a complaint about dumping of Italian tomatoes with the ministry in July 2011.
The report, "Dumping Investigation, Preserved Tomatoes Investigation" found that one, a producer called Conserve Italia Agricultural Cooperative Society, had dumped the products.
"There is evidence of an increase in the volume of dumped imports in absolute terms and in relation to production in New Zealand," the report said.
"There is evidence of only a slight increase in dumped import volumes relative to consumption in New Zealand."
