Drought, tough market conditions and Brexit had added more uncertainty to the sheep industry and farmgate lamb prices had been affected by a persistent strong New Zealand dollar, Federated Farmers president William Rolleston said in a statement.
The dairy industry was still going through "an adjustment of sorts" and it remained the most vulnerable of all farming sectors.
It was no surprise the Reserve Bank continued to highlight dairy as one of the main risks for financial stability, Dr Rolleston said.
In ANZ's latest Agri Focus, economists said current market indicators were pointing towards a $6.40-$6.50 milk price in 2016-17, assuming recent GDT prices could hold through the remainder of the season.
ANZ had a slightly more conservative view of $6.25, based on some moderation of prices in the new year.
The increase in international prices was driven by tightening global milk supply and continued demand from China.
