Fonterra is still by far the biggest cheese in New Zealand's raw milk market with the latest figures showing its processing rivals have yet to make a real fight of the big cooperative's 17-year reign.
Given the growth and geographic expansion of privately owned dairy companies Open Country and Synlait, industry observers had expected Fonterra's hold on the raw milk collection market to have slipped under 80 per cent last season, as competition increased for flat-lining national milk production.
The farmer-owned cooperative started life in a 2001 industry mega-merger with 96 per cent of the market, enabled by special legislation.
But new DairyNZ figures show Fonterra's raw milk market share in the recently ended 2017-2018 season was 81 per cent, just a shade lower than the 82 per cent share recorded the previous season.
Observers suggest that Fonterra's market share has not slipped as steeply as expected despite widening criticism of its financial performance and investment decisions and the growing strength of competitors, because some of its farmer-owners have increased their individual milk production even while national production peaked.
