A website with more information has been launched at www.thekiwifruitclaim.org and advertising in newspapers will begin tomorrow.
A first round of grower meetings will begin next week.
Growers and post-harvest operators have until 5pm Friday, October 24, to sign up to the claim.
"All New Zealanders have an interest in the success of The Kiwifruit Claim because everyone has an interest in government officials being found to owe a duty of care when carrying out their official roles," The Kiwifruit Claim chairman John Cameron said today.
Negligence by Biosecurity NZ is a key finding of an independent report into the outbreak ...
"In particular, all New Zealanders have an interest in government officials properly protecting our borders from pests and diseases that could devastate not just our agriculture and horticulture industries, but the native flora and fauna that we all cherish.
"There is no doubt in our minds that Biosecurity NZ was negligent in how it was protecting New Zealand from Psa and other risks from as far back as 2004.
"Negligence by Biosecurity NZ is a key finding of an independent report into the outbreak by international consultants Sapere, commissioned by the Ministry of Primary Industries (MPI)."
Mr Cameron said the growers initiating The Kiwifruit Claim were grateful to the current government for addressing many of the issues identified by Sapere in its report when establishing the new integrated Ministry for Primary Industries, which includes the old Biosecurity NZ.
He said the growers had earlier notified the caretaker Minister of Primary Industries, the caretaker Attorney-General, local MPs, the Solicitor-General, Zespri, New Zealand Kiwifruit Growers Incorporated (KGI) and Kiwifruit Vine Health (KVH) of their claim.
"We hope to work constructively with the Attorney-General and Solicitor-General to find a way to manage the matter in a timely and non-confrontational way," Mr Cameron said.
