The possible sale of Westland Milk Products to Yili comes as Yili is ramping up expansion at its Morven plant in South Canterbury.
From next month, worker buses will start running daily from Timaru and Oamaru as Oceania undergoes further expansion which is predicted to increase staff numbers at the plant from 300 to close to 400.
Oceania's interim manager Richard Hickson said providing staff buses was a way to attract local staff.
''Our policy is to attract as many local people as possible. Hopefully it will allow us to tap into the Timaru market.
''Positions available will be across the board - engineering, IT roles, process control, management, laboratory, supervisor roles, HR roles, administration and roles that are highly technical.''
