Fonterra Co-operative Group Limited has revised its 2018/19 forecast Farmgate Milk Price from $6.75 per kgMS to a range of $6.25-$6.50 per kgMS.
It has also increased its forecast New Zealand milk collection volumes by 1.3 per cent to 1550 million kgMS.
Fonterra Chief Executive Miles Hurrell says the change in the forecast Farmgate Milk Price was due to a stronger global milk supply relative to demand at this time.
"I know how hard it is for farmers when the forecast Farmgate Milk Price drops, but it's important they have the most up to date picture so they can make the best decisions for their farming businesses.
"We are still seeing strong production coming from Europe, US and Argentina. While the hot weather in Europe has slowed down the region's production growth, it is still tracking ahead of last year. US milk production is up slightly and Argentina's is up 6.8 per cent.
