"As outlined in the data for the three-month period ending October, sales activity has been virtually non-existent in the dairy sector, but lifted well in the finishing and grazing categories," Mr Peacocke said in a statement.
The median price per dairy hectare was down 28.6 per cent during the past year.
Across 20 properties sold during the three months to October last year, the per hectare price was $40,012, while across 11 properties sold in the same period this year, it was $28,555.
Arable, forestry and horticulture all recorded slight increases, albeit the latter saw a "distinct easing" in sales. He noted many farms came on the market in October, which meant would-be purchasers would have "unprecedented selection opportunities".
Around Otago, Peacocke said there was "solid activity" on finishing and grazing properties and interest in forestry.
However, the supply of capital was restricted and affecting the dairy market in particular, due to Overseas Investment Office (OIO) criteria being tightened. Similarly in Southland, the OIO criteria had impacted on sales of the larger dairy units, causing "frustration" in some quarters, he said.
There was otherwise light activity in the dairy sector there, where stocks of quality property continued to build, and there was good activity on finishing, grazing and arable properties, from mainly local buyers, Peacocke said.
