"In addition, consumers are gaining more confidence that everyday products are being produced more sustainably and are more acceptable so they no longer see the need to pay the premium for most organic products."
The company's North Island organic suppliers would be concentrated in one hub around its Hautapu processing site, which would reduce the number of organic suppliers, while the amount of product processed at its two other certified organic sites at Waitoa and Morrinsville would be reduced.
The organic product range priority would be cheese, which provided the best returns.
The plan also included focusing on emerging Asian and Australasian organics markets where there were stronger returns and potential for growth.
There would be a considerable transport and manufacturing cost saving, Wickham said.
"In addition, focusing most of our organic product through a single site will mean we are able to create efficiencies of scale in processing the milk."
Fonterra general manager of milk supply Steve Murphy said the company was committed to an organic offering.
