Federated Farmers' Northland dairy spokesman, Ashley Cullen, said the situation was serious across the board.
"Nobody's safe with this one at the moment. This is not something Fonterra is responsible for, it's a global price and demand issue."
While there would be support via various agencies, farmers should also keep an eye out for each other, Mr Cullen said.
"These are very serious times as we all come to terms with the lower payout. I have not heard any news regarding forced sales but plenty of murmurs about changes in policy regarding lower cow numbers and more beef.
"Some will be unable to do either and may fall, but it's still early days. Northland will be hit harder as we are lower per hectare in production than the rest of the country but our land costs less."
Fonterra also predicted milk production will drop this autumn as farmers cut costs by reducing herds or feeding out less supplements.
In Northland, finding extra feed is unlikely to be a problem. Instead of the predicted El Nino-fired fourth drought in five years, grass and feed crops flourished under perfect summer growing conditions - farmers literally made hay while the sun shone.
Federated Farmers and DairyNZ are holding seminars to help sharemilkers, contract milkers and farm owners plan a path forward over the next year. The Northland event is on March 17 at Barge Showgrounds, Whangarei.
