"A few billion in losses is not a threat to financial stability. The regime that's in place now means the banks are stronger than they've ever been with a greater ability to withstand those losses than they've ever had."
He said there was a system for dealing with extreme hardship "because you are going to see, for a small number of dairy farming families, some real distress. But we're not going to be bailing them out."
But Little said some farmers were effectively now working for nothing and the Government could set up similar emergency provisions to those it uses in cases of drought or other 'adverse events'.
"If the farms in the long term are productive we want to keep them viable. If there are circumstances where a farmer has continued to make reckless decisions and the situation of the farm is not just a consequence of the low dairy payout then you might have less sympathy for that. But where you've got good farmers with good efficient farms then it makes sense to keep farmers like that on the land."
Help for farmers can include tax relief and Rural Assistance Payments for families.
Little said the Government should also call a crisis summit of farmers, Fonterra and the banks to hammer out a way to ride through the hard times. Mr English dismissed that as a "talkfest" and said supporting the Trans Pacific Partnership would be more worthwhile.
The Reserve Bank will this week release stress tests it has done with five major rural lending banks - ANZ, BNZ, Rabobank, Westpac and ASB.
Dairy doldrums
The Reserve Bank's worst case scenario - if dairy prices stay low for three years:
• Farm prices down 40 per cent
• Banks write off 15 per cent of sector loans
