Fonterra has stuck with its $4.70 per kg farmgate milk price forecast for the 2014/15 season and its forecast cash payout of $4.95 - $5.05 a kg, surprising some in the market who had expected a minor upgrade.
The cooperative, the world's biggest diversified milk processor, said that although dairy commodity prices had gone up, the increase was not sufficient to raise the forecast milk price.
The last five GlobalDairyTrade (GDT) auctions have shown price improvements after prices dropped by 50 per cent last year.
"Since December, GDT prices for whole milk powder have increased 45 per cent and skim milk powder prices have increased 13 per cent," chairman John Wilson said in a statement.
"There continues to be significant volatility in international commodity prices," he said.
