As a result, Hewson said the company had reduced the number of permanent employees it has in response to tightening market conditions, increasing costs of labour, inputs and compliance.
Evidence given by industry members, such as Hewson, in the Potatoes New Zealand (PNZ) Pandemic Industry Recovery Plan application, completed in September, has prompted the Ministry for Business Innovation and Employment's (MBIE) trade remedies team to launch an investigation into the threat posed by surplus frozen fries being imported into the country.
Hewson said with New Zealand jobs and livelihoods at stake there was a "very clear case for MBIE to investigate".
"New Zealand jobs and livelihoods are at stake if New Zealand allows importers to view New Zealand as a predatory dumping ground."
He praised the backing of quick service restaurants such as McDonalds, which had spoken out and voiced their support to only use locally produced product in New Zealand and Australia.
"It sets a benchmark we hope all New Zealand food retailers such as Progressive and Foodstuffs will be supporting," he said.
The industry application, completed in September, was in response to the initial threat increased dumped imports of surplus European frozen fries posed to the New Zealand potato processing sector, combined with supply chain disruption effects caused by Covid-19.
At the time the surplus in Europe was 1.5million tonnes, but latest figures were estimated at 2.6million tonnes and growing due to the impacts of further lockdowns in parts of Europe.
The situation was not unique to New Zealand's potato industry, with those in the United States, Australia and South Africa also calling for duties or actions to limit or enforce anti-dumping measures.
