Alliance Group has confirmed it will shift sheep meat processing from its Mataura plant near Gore to its Lorneville plant outside of Invercargill.
The company says all the processing workers who have been affected will be offered jobs
at the Lorneville Plant but there are likely to be redundancies among management, supervisors, engineers and administration staff.
It says the shift from Mataura had to be made because of a surplus of processing capacity and the declining amount of stock.
The Meatworkers Union says it does not know yet how many displaced employees from Mataura will transfer to new jobs.
All 260 processors who worked on the sheep chains at Mataura have been offered jobs at Lorneville.
Otago-Southland secretary Gary Davis says members have to weigh up considerations such as the extra travel involved and shift work.
They have until Friday next week to decide and those who opt not to take the offer are eligible for redundancy.
Alliance says there will also be some redundancies among the 65 management, supervisors, and trades staff at Mataura.
