Milk collections for the season to date were up 10 per cent on the same period in 2011, flowing into record production which saw a new export volume record in December, van der Heyden said.
International dairy prices softened after last year's highs but were fairly stable in the first half, supported by strong demand for quality product in emerging markets in several Asian economies, Brazil and China, offsetting economic uncertainty in Europe.
Van der Heyden said prices were very similar to those in the first half of the previous year, before spiking up towards the end of the financial year. But the past six months had its fair share of disruptions - a Canterbury snowstorm, a break in the Maui gas pipeline, and Northland floods all gave the company some anguish.
Chief executive Theo Spierings said milk production overseas was increasing. "There's ... softening of prices because of greater produc-tion around the world. The supply side is growing, but the demand side is going much faster," he said.
Fonterra's standard and premium ingredients businesses had a strong first half, with a 10 per cent lift in revenue to $8 billion achieved from higher sales volumes, and a 10 per cent increase in average US dollar sale prices.
Consumer business results were mixed, our high dollar affecting returns from Asia/Africa, Middle East and Latin America.
The Australia-New Zealand consumer business felt pricing pressure which reduced earnings.
Spierings said the company's "group strategy refresh" for the next decade focused on geographies and products that would deliver the best growth opportunities.
Fonterra's gearing ratio, up at 59.6 per cent by the end of the global financial crisis, dropped to 46.9 per cent from 48.5 per cent in the previous corresponding period.
