The New Zealand dollar fell after prices for the nation's largest commodity export declined in the latest GlobalDairyTrade auction overnight.
The kiwi weakened to 77.91 US cents at 8am in Wellington, from 78.76 cents at 5pm yesterday. The trade-weighted index dropped to 78.25 from 78.71 yesterday.
Dairy product prices slipped to a fresh five-year low in the latest fortnightly auction, because of a drop in whole milk powder. The GDT average winning price slid 1.1 percent to US$2,513, the lowest level since August 2009, and down from US$2,561 two weeks ago.
The kiwi also faced headwinds from a stronger US dollar after Federal Reserve vice chairman Stanley Fischer said the Fed was coming close to removing its pledge to keep rates low for 'a considerable time', signalling rates could rise in six months. The US dollar index, which measures the greenback against a basket of currencies, touched 88.651, its highest in more than four years.
