The New Zealand dollar declined after US economic data kept alive expectations the Federal Reserve may hike interest rates this month.
The kiwi slipped to 63.42 US cents at 8am in Wellington, from 63.63 cents at 5pm yesterday. The trade-weighted index dropped to 68.86 from 69.04 yesterday.
The US dollar index, which measures the greenback against a basket of currencies, advanced on signs the US economy is continuing to expand. The ADP employment data showed US private payrolls increased 190,000 last month.
While short of expectations for about 200,000, it's a step up from the 177,000 positions created in July.
Meanwhile, the Fed's Beige Book snapshot of economic conditions across its 12 districts showed economic activity continued expanding across most regions and sectors during the reporting period from July to mid-August.
