Dairy farm prices are dropping, according to latest sales figures.
The institute's Dairy Farm Price Index fell by 13 per cent in the three months to July compared to the three months to June. Against July last year, the index fell by 12.1 per cent.
REINZ rural spokesman Brian Peacocke said Fonterra's move to cut its farmgate milk price forecast to $3.85 a kg of milksolids from $5.25 a kg had confirmed widespread expectations among farmers.
"The key issue for many is the time prices are likely to remain at current levels, with particular concerns being expressed for lower order and 50/50 sharemilkers," he said in a statement.
"Banks generally appear to be supportive, but conversations are taking place given circumstances being appropriate," he said.
