"Land is a long-term investment and overseas investors will have very long-term horizons and they're less likely to pull out, but see this as a good chance to buy if the asset values are falling."
Penny expected more farms to hit the market.
"There's normally a strong relationship between milk prices and rural land prices. What we've seen this last time is the milk price for the season just finished is about half what it was in 2013/2014. It's a chunky drop.
"We haven't actually seen much movement in land prices which is a bit of a surprise but now we're going to have another low season, we do think eventually that will filter through to land prices," Penny said.
"There will be a level of stressed sales or even forced sales. There will be some restructuring within farms, so farmers may look to consolidate. They may have multiple farms and just sell some. In terms of farm sales, will the level increase? That's a little more complicated," he said.
"Generally, when things are buoyant the level of sales is higher so you wouldn't expect the level of sales to increase, but the prices would drop because basically there will be less willing buyers. The same rules that apply in the housing market will apply in the rural market."
Jacqueline Rowarth, professor of agribusiness at Waikato University and who has a 5 per cent share in a dairy farm, is hoping mortgagee sales can be avoided.
"The banks are trying not to foreclose. If they do, land prices will fall and other people will be in strife because their debt-to-equity ratio will be completely wrong," Rowarth said.
"So the banks are encouraging the dairy farmers to capitalise the interest on their loans, assisting in a positive route. They're trying to help with lower interest rates on any environmental aspects of dairy farming, so they're trying to help."
Brian Peacocke, Real Estate Institute of New Zealand (Reinz) rural spokesman, said it wouldn't be until later this year that the effects of falling dairy payouts might be reflected in sales volumes. But he doubts land prices would drop dramatically.
"The market has not yet reacted to where the dairy payout is," Peacocke said, referring to the latest Reinz figures which showed that for the three months to June, the median dairy farm sale price was $35,531/ha based on the sale of 64 properties. That was up slightly on the $35,281/ha for the three months ended May, based on 87 sales.
Dairy farmers are now busy with calving and they're "flat-stick, too busy with seasonal issues and they don't want anyone on the property", Peacocke said.
Come spring in September and October, the situation might have changed with potentially more properties changing hands but that data would not emerge until November, Peacocke said.
Falling interest rates and the falling dollar were just some of the factors offsetting lower dairy payouts, he said, so the news was not all bad.
"There's not [a] suggestion of forced sales," Peacocke said, adding that Reinz made no projections on land prices.
