Chief executive Michael Franks said overall, the damage seemed less severe than was initially feared and represented only a small percentage of Seeka's expected supply for the coming harvest season.
It would take some time before the total losses in terms of trays could be estimated and a small number of growers had incurred significant damage, he said.
Seeka was also advising growers on how to mitigate any possible Psa-V risk for damaged crops, he said.
About 35 hectares of orchards that Seeka supplied have suffered significant damage, with another 50 to 75 hectares that were less affected. The majority of damage was in kiwifruit orchards.
