On June 23, Fonterra lifted its 2022/23 forecast by 50 cents to between $8.75 - $10.25 per kgMS, from an opening range of $8.25 - $9.75.
The revised 22/23 forecast midpoint, off which farmers are paid, stands at $9.50.
Fonterra chief executive Miles Hurrell said he wasn't worried about the result, as it was expected.
"Some of the sentiment that we'd picked up in the last few weeks is starting to play out," he told The Country's Jamie Mackay.
Softening demand out of China had "played its part" with a drop across the board, Hurrell said.
China often had an influence on the result, he said.
"It's one of those markets that if it works - it works very well - and we've seen that play out in the last few years and it's underpinned the milk price very much over the last couple of years."

However, when China was "doing it tough," such as with its current strict Covid restrictions, it made it "a little bit more difficult," Hurrell said.
"We've seen a general slowdown in their macroeconomic situation and [China's] general slowdown globally on a commodities front, and we feel that pain.
"So, that's playing out in the result you saw last night."
Hurrell said there was "nothing to suggest any change" to the 21/22 season forecast midpoint of $9.30 - but it wouldn't be finalised until around September 23.
As for the 22/23 forecast midpoint of $9.50, Hurrell said Fonterra would "have a good hard look" at it, but wouldn't confirm whether it would drop.
"A lot can play out. We've seen some short-term issues at the moment, but that medium-term and even the long-term picture still looks favourable."
