New Zealand's dollar sagged amid a slide in consumer confidence, while cryptocurrency ether climbed to a record high.
The dollar index, which measures the currency against six main rivals including the euro, was little changed at 93.354, close to Thursday's low at 93.277 - a level not seen since Sept. 27.
The euro was largely flat at $1.16855 after rising as high as $1.1692 overnight for the first time since Sept. 28.
Against the yen, another traditional safe haven, the dollar was mostly unchanged at 113.50, continuing to ease back gradually from the almost three-year high of 114.695 reached last week.
An index of global shares rose to the cusp of a record peak this week, powered by an earnings-driven rally to consecutive record highs on Wall Street, including overnight.
