Producer prices have fallen, due to lower dairy prices.
Official figures show the producers price input index fell 0.4 percent in the three months to December, compared with the previous quarter.
In turn, the prices producers charged customers fell 0.1 percent.
Statistics New Zealand said lower prices received by dairy manufacturers and paid to dairy farmers are the main contributors to the declines.

On an annual basis, job adverts rose 6 percent. Internet advertisements rose, but newspaper adverts fell heavily, though ANZ expects a rebound in February.
