The Hauraki region has been hit by heavy rain three times in the space of a month - and some land is unlikely to be usable until Spring.
Dairy Farmer Fred Dijkstra says parts of his run-off block in Patetonga have been flooded and some of it will be out of production for months to come.
And he says he's yet to estimate the cost for him personally.
"I can't put a price tag on that one, I can't put a price tag on the flood. There were seventy bales, they are gone. But I don't want to complain, we had to move stock home, so that's 150 animals for cartage and now we have to feed them at home. There's always a bit of a risk in farming you know."
While much of his property is unusable, some of his crops were saved.
