"Steady improvement in dairy commodity prices over the second half of the past year resulted in farmers spending on deferred maintenance and increasing milk production," Mair said. "This boosted earnings in both New Zealand and in our major overseas markets. Current indications suggest that momentum is set to continue."
For the agricultural unit, earnings before interest and tax rose to $19.8m from $18.8m, while revenue remained little changed at $79.2m from $79.6m, which Mair said reflected an improvement in the profit margin due to a favourable shift in market and product mix.
In the industrial unit, ebit rose to $17.1m from $15.3m even as revenue slipped to $131.2m from $132m.
"We have focused on improving our operational performance, and this work is starting to show in our financial results," Mair said, adding that he was confident it was capable of further improvement in the 2018 financial year.
