Farm prices are on the way down, led by an 18 per cent decline in the dairy sector over the past 12 months.
Real Estate Institute of NZ (REINZ) data showed prices for most farm types were down in June but that dairy copped the worst of it, reflecting below-cost dairy product prices.
Across the board, sales volumes eased significantly in all categories apart from horticulture, which remained stable, the institute said.
The Reserve Bank carried out a "stress test" of the five largest dairy lenders late last year to assess the banking system's vulnerability to the sector if product and farm prices continued to decline.
In a report released in March, the central bank said two scenarios were tested. The first scenario assumed that the dairy payout would recover to $5.25 per kilogram of milksolids by the 2017/18 season and that there would be a fall in dairy land prices of 20 per cent. Under the second scenario, the dairy payout was assumed to fall to $3 a kg in 2015/16 and remain below $5 until the 2019/20 season, with a fall in land prices of 40 per cent.
