The New Zealand dollar advanced as investors shied away from placing further bets that the greenback would rise.
The kiwi rose to 78.42 US cents at 8am in Wellington, from 77.90 cents at 5pm yesterday. The trade-weighted index gained to 76.52 from 76.06 yesterday.
Investors eschewed placing further bets that the US dollar would rise as data from the US Commodities Futures Trading Commission showed the net number of 'long' positions, betting the greenback would likely rise in value, is at its highest since almost 2002, excluding a jump last year on the Federal Reserve pulling back its quantitative easing programme.
The dollar index, which measures the greenback against a basket of currencies, fell from its highest in more than three weeks, even after a report showed US third quarter gross domestic product rose at a 3.5 percent annual pace, beating expectations for a 3 percent gain.
