The Greens are urging the Reserve Bank to cut the official cash rate next week after inflation dipped below the bank's own target.
Figures from Statistic New Zealand today put the annual rate of inflation at 0.8 percent, its lowest point for almost 13 years.
The consumers price index rose 0.3 percent in the September quarter – half the increase tipped by economists.
The annual rate has not moved by such a small amount since it rose 0.5 percent for the year to December 1999.
Annual inflation is below the Reserve Bank's 1 to 3 percent target and Greens co-leader Russel Norman says it can afford to cut the rate next Thursday.
"Low inflation gives the Reserve Bank generous scope to cut the OCR as a first step to addressing our overvalued currency," he said.
He says a cut was likely to result in a decline in bank interest rates, which could work to lower the value of the New Zealand dollar.
The Greens want the Government to print money to lower the exchange rate to help manufacturers and exporters and fund the Christchurch rebuild, but the Government has rejected both measures.
