Ornua’s purchasing price index (PPI) for the month of April 2026 rose 4.2% to 127.0.

This is the Ornua PPI's highest level since December 2025 and April's increase follows a marginal index lift for March.

The PPI implies an indicative return of 33.97c/l excluding VAT for April’s milk at base constituents net of Ornua costs to the market and having deducted estimated processing costs for last month.

This is an increase on the 32.73c/l ex VAT, that had been quoted by the processor for March.

The estimated cost of member co-ops’ processing costs increased 0.5c/l to 9.5c/l, Ornua said.

The processor noted that this estimate is based on the average cost of processing the Ornua basket of products, which is not representative of any individual member co-op processor.

It also excludes a member co-op margin.

The announcement of positive Ornua PPI movement came after Tuesday’s Global Dairy Trade (GDT) auction in New Zealand saw average prices lift by 1.5% in the first auction to see an index boost since mid-March.

The average prices paid for both whole and slimmed milk powders increased, but butter prices fell.
