DairyNZ's latest economic survey showed dairying was more successful and critical to the economy ''than ever before'', but it had become a tougher and riskier business, DairyNZ chief executive Tim Mackle said.
New rules and regulations to farm within nutrient limits would bring more challenges and put extra pressure on the industry's ability to stay competitive internationally, he said.

Farmers were operating with higher levels of debt, with interest payment costs that had doubled in the past 10 years despite the record low interest rates.
That was an area of concern as it meant an additional 60c-70c kg/ms in revenue was required to meet the extra interest payments, Mr Newman said.
