In a market update on October 15, Fonterra increased the midpoint of its forecast farmgate milk price for the 2020/21 season by 40 cents to $6.80, but retained its $1 range of between $6.30 and $7.30.

"What it means is 145 million New Zealand dollars into the economy," Rivers told The Country's Jamie Mackay.
Strong participation from China contributed to the 5 per cent leap in Whole Milk Powder, while Skim Milk Powder's rise of 3.6 per cent meant it was around a $450 premium compared to European and US competition, Rivers said.
"So people are clearly valuing the provenance of New Zealand and the way we make the powder."
Butter's rise of 3.8 per cent meant it was "about to touch 4000 US dollars per metric tonne," but the strong result was difficult to pin down to Covid-19 restrictions in the Northern Hemisphere, Rivers said.

"On the one hand people are baking more at home for sure, on the other hand, the big use of butter would be at restaurants - so it's quite a switch there - and hard to see how exactly that's going to play out."
Meanwhile, Fonterra's milk volume forecasts were "still about the same" as what was projected at the start of the season, despite predictions of a La Niña summer, Rivers said.
