Increasing environmental regulation, high farm debt and low profitability means New Zealand dairy farmers will have to grind out the next 10 years, according to Dr John Penno, othe co-founder of New Zealand infant formula company Synlait. Speaking at Dairy Day 2019, Penno said New Zealand milk production had reached its peak five years ago and that the next decade up to 2030 would see little room for expansion or new entrants in the New Zealand dairy industry.
