Open Country Dairy, New Zealand's second-largest milk processor, generated more than $1 billion of revenue last year but payments for milk rose faster than receipts from customers and profit fell.
Profit was $23 million in the year ended September 30 from about $62m a year earlier, its accounts show. Sales rose 34 per cent to $1.1b while cost of sales gained about 44 per cent.
Open Country did not disclose volume figures in its public annual accounts but chair Laurie Margrain said it was up on a year ago.
"We have more market share, more farmers supplying us," he said. "We've got more of the market than a year ago and hugely more than 10 years ago."
You've got to be competitive on the price you pay for milk.
