"For the season to date, we have processed more cattle this year than the previous year."
Alliance Group is one of North Otago's biggest employers and the change would create a longer season for staff, "providing increased earnings and greater opportunities for staff training and development", Surveyor said.
"This beef expansion reflects our commitment to the Pukeuri plant, which is an important part of our network and the region."
Alliance Group is consulting with staff and the New Zealand Meat Workers and Related Trades Union over the proposed changes, which will take effect later this year.
No redundancies were expected.
During the peak season each year, Alliance employed almost 5000 people across its seven plants and offices, Surveyor said.
This year, it had increased its bovine network capacity by 10 per cent and the proposed changes at Pukeuri would give the company "additional capacity beyond that".
"Our focus on increasing beef capacity and moving stock across our networks means that we have been able to create additional roles across our plants and lengthen the employment season for our people."
While there will be a reduction in ovine capacity at Pukeuri, there will be no changes to ovine processing capacity across Alliance's plant network.
