Fonterra in February lifted its 2021/22 forecast farmgate milk price range to NZ$9.30 - $9.90 per kgMS, up from NZ$8.90 - $9.50 per kgMS.
This increased the midpoint of the range, which farmers are paid off, by 40 cents to $9.60 per kg, which would be the highest ever paid.
While the event result was "disappointing," it was due to "short-term issues," Fonterra chief financial officer Marc Rivers said.
The biggest of these was Covid, especially how it was affecting China and indirectly impacting other economies such as Sri Lanka, Rivers told The Country's Jamie Mackay.
Fonterra's long-term outlook had remained consistent, Rivers said.
"We've still got pretty steady demand out there. Supply remains pretty constrained but we do have a confluence of short-term issues that are showing up in last night's GDT event."
The co-op was keeping an eye on China's zero-Covid policy as well.
"You can't really go around the storm you have to go through it. So, it's a matter of how China gets through it and what that means for consumer demand."
Rivers remained cautiously optimistic about China, despite its lockdowns and the threat of Omicron.
Listen below:
"To some extent, we saw this two years ago when China first went through it and managed to bounce back pretty quickly.
"I think Omicron is a different beast so we'll see how quickly things can bounce back to where consumers are able to consume what they want and go out shopping.
"At the moment the lockdowns are pretty severe and this is having an effect."
