Westland Milk Products has recorded its highest ever one-day milk collection, with tankers bringing in just over four million litres of milk on 31 October.
The dairy co-operative's farmer-shareholders have lifted production by more than 5 percent from last year, in line with the national increase of 5.4 percent.
Westland chief executive Rod Quin said the mild winter followed by dry conditions during calving may have been a factor.
"It's been very wet in the last few weeks, that said ... but (for) most farmers it's been a case of utilising pasture rather than relying on supplementary feed. Grass will be the cheapest input that farmers can feed cows.
Farmers had had a difficult year, which has affected cash flows, and had begun to reduce inputs.
"They spend less, so things like fertiliser, supplementary feed, everything gets questioned, and at some point they will look at de-stocking as well," said Mr Quin.
"But most farmers being adaptable and resilient will get through the next period. It's really a question of whether these lower prices will continue for longer into the 2015/2016 season.
"And I have to say at this stage we don't think they will, we think the market will correct itself."
