If this trend continued there could be a potential dairy herd shortage in the market, Cunninghame said.
Some quality dairy herds were fetching up to $16-$18,000 in the North Island and a bit higher in the South Island.
Mackay recalled when top dairy cows were selling for $2,500.
Mackay asked about the process of selling and buying herds.
Cunninghame explained that herds were sold via forward contracts which were settled through May and June, and then there were on farm clearing sales which started now until early June.
