Last year SFF closed Mossburn in northern Southland and Frasertown in Wairoa, which cost a total 110 jobs.
After Fairton's closure, SFF would consolidate the region's sheep processing to Pareora, about 10 minutes south of Timaru, where the company had spent $7million the past year improving cold storage capability and installing a state-of-the-art venison line.
It would now invest a further $1million to support consolidation of Fairton's sheep volume, Mr Hamilton said.
He said the more than $260million investment by Shanghai Maling last December into SFF to form a 50:50 partnership enabled SFF to invest $22million in capital expenditure this year, an almost threefold increase on the $8million spent the year before the Shanghai Maling deal.
The capital expenditure included health and safety improvements, robotics systems, processing room upgrades and more efficient cold chain infrastructure, with over $20million expected to be spent annually, he said.
The Fairton pelthouse would remain in operation with no decision made on the wider site.
