The New Zealand dollar gained ahead of a speech by outgoing Federal Reserve chairman Ben Bernanke, and as US data and minutes to the last Fed policy meeting loom.
The kiwi rose to 83.43 US cents at 8am in Wellington from 83.10 cents at 5pm yesterday. The trade-weighted index advanced to 77.79 from 77.55 yesterday.
Investors are awaiting Bernanke's speech on communications and monetary policy to the National Economic Club on Tuesday in Washington, where they will be looking for hints on when the Fed will start unwinding its US$85 billion monthly asset purchase programme.
That comes ahead of the release of US consumer spending figures and the minutes to the Federal Open Market Committee's last policy meeting, which will also be used as a gauge as to when the Fed might start tapering stimulus.
"I'm not expecting much from Bernanke in the speech, if there was a surprise, it would probably be US dollar positive," said Sam Tuck, senior manager FX at ANZ New Zealand in Auckland. "Bernanke still presides over the December meeting, but there's a low probability of the Fed changing its policy - we're predicting no change before March."
