The kiwi "is absolutely surging forward", said Stuart Ive, senior dealer, foreign exchange, at OMF. "People are unwinding some of that US dollar risk, they are posting some money with the high yielders over the Christmas period and hence the strong move in the kiwi."
The GDT auction saw average dairy prices rise 3.6 percent while whole milk powder prices increased 5.3 percent. That added some doubt as to whether the Reserve Bank of New Zealand will cut interest rates next week, Ive said.
In contrast, weaker US data and comments by Chicago Federal Reserve president Charles Evans that he would like to have more confidence about rising inflation before raising US interest rates, and that he favours a gradual pace of increases weighed on the greenback, Ive said.
"I still think the Fed will hike this month but the path forward may not be as rosy as some had previously thought and this is leading to what has been a very heavily populated trade of long US dollars, people are exiting, just unwinding risk, and that's what we are seeing with the kiwi," Ive said. Fed chair Janet Yellen is due to speak today.
Today, the local currency has support at 66.40 US cents and faces resistance at 67.10 cents, Ive said. The kiwi could advance to 68 US cents, he said.
The New Zealand dollar was little changed at 91.04 Australian cents from 91.07 cents yesterday ahead of the release of Australian third-quarter gross domestic product.
The local currency advanced to 62.78 euro cents, from 62.56 cents yesterday, gained to 44.24 British pence from 43.88 pence, rose to 81.96 yen from 81.32 yen, and increased to 4.2710 yuan from 4.2357 yuan.
