Westpac has revised up its farmgate milk price forecast for 2016/7 to $5.00 a kg of milksolids from a previous forecast of $4.60/kg on the back of big gains in international dairy prices.
A $5.00/kg milk price would compare with DairyNZ's estimated average break-even point of $5.05 a kg.
Fonterra's current forecast is for a farmgate milk price of $4.25 a kg.
World dairy prices rallied sharply at the latest GlobalDairyTrade (GDT) auction, driven mostly by double digit gains in whole milk powder and butter milk powder.
Overall, the GDT price index gained by 12.7 per cent since the last sale on August 3, which itself showed a 6.6 per cent gain.
