Mr Foss, the Minister of Veterans Affairs, who is in Turkey representing New Zealand at the Battle of Chunuk Bair centennial, said in the letter: "I am fully aware of the potential negative impact on you, Bay families, and businesses, if the Automatic Termination Period provisions of any dumping protection is brought in.
"I am also very concerned at the massive uncertainty any 'gap' in protection, between successful anti-dumping protection applications will create," he said.
"Such uncertainty and anxiousness is, to me, unacceptable. I have made your concerns, which are also my concerns, very clear to the Minister of Commerce and Consumer Affairs (Paul Goldsmith)."
He was confident Mr Goldsmith, Primary Industries minister Nathan Guy and the Government "fully understand your anxiousness, and how strongly you rightly feel about this issue".
Mr Foss said Mr Goldsmith had stressed no final decisions had been made, and that responses during the consultation process had "most certainly not gone unnoticed".
"As your Hawke's Bay MP, I will continue to speak regularly to Minister Goldsmith on this issue and will take every opportunity to reinforce to him the views you have expressed."
Mr Foss said officials have now presented "a number of options" to ministers.
"The Government will discuss the issue, take on board all of the points raised, and make its decision in the coming weeks," Mr Foss said.
"I will continue to push back on the ATP proposal."
Mr Foss said Fruitgrowers president Lesley Wilson, Heinz Wattie's managing director Mike Pretty and agronomist Bruce Mackay had done an excellent job on behalf of the industry to show how the proposal could impact not only the peach industry in the Bay, but also the pear industry and the processing plant in Hastings.
