The New Zealand dollar fell against the greenback amid speculation the Federal Reserve will further trim its bond buying programme when it reviews policy next week.
The kiwi fell to 83.06 US cents at 8am in Wellington from 83.22 cents yesterday. The trade-weighted index was little changed at 78.81 from 78.86.
The Dollar Index, a measure of the greenback against a basket of currencies, rose as markets latched on to a Wall Street Journal report by Fed watcher Jon Hilsenrath predicting the US central bank will cut another US$10 billion from its monthly asset purchases to US$65 billion when it meets next week. Barring a weak employment report for December, the world's biggest economy has been showing signs of recovery in recent months, giving the Fed scope to pull back its stimulus.
"Keeping the US dollar underpinned are expectations of further tapering," said Imre Speizer, market strategist at Westpac Banking Corp in Auckland. "That's proving to be a headwind for the kiwi."
Westpac's Speizer said the local currency has support at 83 US cents, though if it breaks below that level, "we should see it go half a cent lower."
