The New Zealand dollar advanced as the greenback fell from its highest level in more than four years following weaker US trade data and declining oil prices.
The kiwi rose to 77.75 US cents at 8am in Wellington, from 77.44 cents at 5pm yesterday. The trade-weighted index gained to 76.58 from 76.29 yesterday.
The dollar index, which measures the greenback against a basket of currencies, declined after touching 87.406, its highest level since June 2010. The US trade deficit widened in September as exports cooled from a record. Currencies of oil exporting nations such as Norway, Canada and Russia declined after crude prices fell to their lowest in three years.
The New Zealand dollar gained after failing to hold below 77 US cents yesterday, underpinned by the nation's higher interest rates compared to rates in other major economies.
