The Department of Conservation says it is unlikely that any new kakapo chicks will hatch this year.
The kakapo is on the brink of extinction, with only 125 of the native birds remaining.
A recovery programme on Codfish Island recorded 15 nests, but a cold and wet southern spring has had an effect on the food supply.
DoC southern area manager Andrew Roberts told Nine to Noon the females will not breed if there is not enough food.
He said the males are continuing to make their mating calls, but if nothing happens within the next few days, it will be the second year running with no kakapo chicks.
