"The papers are full of farms being forcibly sold up and farm company liquidations," Mr Guest said.
"One has to question the banks' responsibility for this current farm crisis. The old Rural Bank guidelines, that you borrowed no more than four times your gross income, debt servicing was limited to 25 per cent of your gross income and the number of farms you could own, were monitored by the Land Aggregation Act.
"One has to question, have the banks today been irresponsible in the way that the old lending criteria have been thrown out the window? What were the bank risk managers thinking when bank lending has put 2200 dairy farmers at risk?"
The government had given New Zealand banks financial guarantees, but that did not extend to providing direct Government assistance to farmers now facing foreclosure.
"It is clear that the government does not view itself as the people's safety net," Mr Guest added.
"However, those farmers who believe their banks have not treated them fairly should complain to the Banking Ombudsman and seek professional advice."
Farmers of New Zealand could provide professional services.
