Fonterra has finally jumped on the A2 bandwagon as the small rival company has grown in strength over the past decade and has just announced one of its strongest profits - sending its share price to a record high.
Spierings added that the companies share the same priority on producing premium milk products and that a2MC products promoted by the new partnership fit well within its overall portfolio.
A2 Milk says A1 and A2 proteins affect digestion differently, and its products may benefit people who experience discomfort from drinking cow's milk.
Under the new agreement, Fonterra will build a pool of farmer-suppliers in New Zealand and Australia, which will require genetic testing to identify the A2-producing cows.
A2 revealed in its interim results release yesterday that it had formed a strategic relationship with Fonterra that would cover a wide range of supply, distribution, sales and marketing arrangements in some markets, saying it was a "significant development [for the company] given the wide-ranging nature of the relationship", helping it build its business in new markets.
The two companies will establish an A1 protein-free milk pool in New Zealand and a new A1 protein-free milk pool in Australia, and Fonterra also gets exclusive supply rights for some products in new markets for a2 in South East Asia and the Middle East up to a specified volume.
Some A2 milk is already available in New Zealand outlets under some smaller independent brands such as Fresha Valley.
"A2 is another consumer choice, like organics".
The A2 milk will be processed at the Fonterra factory in Darnum on a segregated processing line separate to the rest of the production facilities.
Synlait and The a2 Milk Company have an exclusive long-term supply agreement for the production of the a2 Platinum infant formula range for China, Australia and New Zealand.
The deal means A2 Milk Company's fresh products will become more available in New Zealand and Australian shops.
A2 refers to the beta-casein proteins found in milk. It sources locally for its fresh milk in Australia, the United Kingdom and U.S., and gets supply for its formula from Synlait in the South Island.
Net profit after tax was NZ$98.5 million ($72.3 million) for the six months to December 31, up about 150 percent from a year earlier, the company said.
