Fonterra's forecast for the current season, which ends on May 31 sits at $4.70 a kg, compared with AgriHG's estimate of $4.51 a kg.
Earlier today, Hokitika-based co-operative Westland Milk Products said it had cut its forecast payout for the current season to $4.90-$5.10 per kg of milk solids, before retentions, compared with previous forecast of $5 to $5.40 a kg.
Westland Milk chief executive Rod Quin said prices were such that a $5.20 payout seemed possible before the recent GlobalDairyTrade auctions, as buyers looked to New Zealand to secure supply ahead of the dry conditions during January and February.
"However, customer sentiment has now changed significantly," Quin said in a statement.
Skim milk powder out of Europe is being offered at US$2,100 - $2,200 per tonne - well below offers from New Zealand of $2,600 - $2,800 a tonne and GDT prices of $2,300 to $2,400 a tonne.
