Jobs are likely to go at New Zealand's second largest dairy co-operative, Westland Milk Products.
The co-operative is reviewing staff roles throughout the business including Westland Shanghai and EasiYo.
Westland lost more than $14 million in the 2015/16 season. Its farmers were paid one of the lowest milk prices in the country of $3.80 per kilo of milk solids.
Chief executive Toni Brendish said current milk payout predictions are higher for the next two seasons but are still not where farmers need them to be and the group wants better returns.
Ms Brendish said the review was part of an overall effort to gain efficiencies and reduce costs. The current structure, including staff roles, was not set up in the best way to deliver the results they want.
The review was likely to result in some staff redundancies, Ms Brendish said. She would not speculate on how many.
The review is due to be completed by the end of the month.
