The New Zealand dollar fell after Chinese figures showed a bigger-than-expected drop in imports last month, which weighed on the currencies of countries that ship commodities to the world's second-largest economy.
The kiwi fell to 66.74 US cents as at 5pm in Wellington from 66.97 cents yesterday. The trade-weighted index fell to 71.45 from 71.57 yesterday.
China's imports tumbled 17.7 percent in September from a year earlier, more than expected, while exports slipped just 1.1 percent, leaving a trade surplus of 376 billion yuan, or about US$59 billion.
The Australian dollar also fell after the trade figures. Australia counts China as its biggest market, while for New Zealand it is the second-largest after Australia for exports, including dairy products.
"The trade figures were slightly bearish for the kiwi," said Imre Speizer, a strategist at Westpac Banking Corp.
