RJ Flowers is made up of 80ha of apples, pears and kiwifruit and is a family operation, which hires between 50 to 120 employees, depending on the time of year.
"The impact could be pretty big as essentially we wouldn't be able to commercially do what we are doing."
A concern for Mr Evans was also based around the technicality of consents.
He said he understood that the WCO wouldn't impact existing consents, however when one was renewed or reapplied for the restrictions would come into play.
"At the end of the day we won't know what is true or false til the hearing process but council is saying that when a consent expires and is reapplied for it becomes deemed as a new one."
He then read a story from Forest and Bird saying that wasn't the case.
"Council accesses the merits of consents but I guess time will tell who's right and who's wrong."
However, he understood there had been a lot of reported facts that people were debating whether they were true or not and from an orchardist point of view they wouldn't know the full effects until it goes through the hearing process.
"What I have been saying is only what I believe is going to happen and is my own personal view. Our understanding is growing day by day and I don't think anyone has a full understanding of it until it goes through the courts."
