Fonterra yesterday said it was offering its farmer members two opportunities to lock in the price paid for a percentage of their milk in the 2014/15 season following a successful trial run of the scheme in the current season.
Fonterra said a guaranteed milk price (GMP) would be offered on 60 million kg of milksolids in two tranches. Applications to supply 40 million kg would open in June, offering a 12 month GMP.
In December, applications would open to supply 20 million kgMS with a six month GMP offered on production from December 1.
The guaranteed milk price for the 2014/15 season followed a successful pilot involving 328 farmers who supplied 15 million kgMS for a guaranteed price of $7 per kg this season.
