Ms Higgins says the increased competition for milk is most likely to impact on Fonterra, Open Country Dairy and Westland, as the most exposed processors to adverse shifts in their existing supply base in relation to their current plant capacity.
She expects farmers in the Waikato, Southland and Canterbury regions to be the most likely to benefit from increased competition, with three new plants in the pipeline over the next two years.
National dairy statistics show in 2015/16 dairy companies processed 20.9 billion litres of milk, down from 21.253 billion litres in 2014/15.
The statistics also show there were 2.3 million dairy cows in New Zealand in the 1985-86 season, with the national herd growing to 4.9 million dairy cows in 2015/16 - 280,435 of them in Northland with 77,572 in 263 herds in the Far North district, 99,656 in 306 Whangarei herds and 103,207 in 338 Kaipara herds.
Meanwhile, Beef + Lamb New Zealand's (B+LNZ) Economic Service said New Zealand's beef cattle herd increased by 2.8 per cent to 3.6 million head during the past year as farmers move toward profitable livestock that are less labour-intensive than dairying.
Northland is grouped with Waikato-Bay of Plenty for the Economic Service's annual stock number survey, which estimates the northern regions have 1,179,000 beef cattle this year, compared with 896,000 on the East Coast and 413,000 in Taranaki-Manawatu - a total of 2,545,000 for the North Island, more than double the 1,089,000 beef animals in the South Island.
Northland-Waikato-BoP total beef cattle decreased 1.6 per cent in the year to June 30, with the decline driven by increases in all classes of cattle except weaners, plus an extremely wet autumn and high store cattle prices leading to farmers not replacing cattle sold with the usual number wintered.
B+LNZ said anecdotal reports from farmers suggested cattle had become too expensive and they expected a reduction in prices.¦
