Fonterra's partnership with the a2 Milk Company (a2MC) is unlikely to impact on dairy farmers in the South for some time, with Fonterra confining its a2 processing to a single site in the North Island in the meantime.
''We've been watching the development of the a2 market for a number of years,'' the head of Fonterra Farm Source in Southland Mark Robinson said.
''While the market continues to grow, ultimately it will be consumer uptake that drives Fonterra's plans.''
He said that while Fonterra markets a2 products under the Anchor label, most of its production goes into ingredients for the Asian market.
At present, the co-operative's processing is confined to 100 farms supplying the Hautapu plant in the Waikato.
