The industry group DairyNZ estimates that one quarter of dairy farmers will have difficulty paying their bills without incurring more debt if Fonterra's reduced farmgate milk price comes to pass.
The farmer-funded DairyNZ said the drop in Fonterra's forecast milk price for the 2014/15 season to $4.70, from its previous forecast of $5.30, would test dairy farmers.
"We've calculated that around a quarter of dairy farmers are facing some business risk this season at the $4.70 milk price," DairyNZ's chief executive Tim Mackle said. "That means they will have difficulty meeting their interest payments, rent and farm working expenses without incurring more debt," he said in a statement.
While managing in a low payout year is nothing new for many farmers, the $4.70 milk price would be one of the lowest in the past six years.
