The New Zealand dollar advanced as commodity currencies were bolstered by an increase in oil prices and as the US dollar continued to weaken.
The kiwi traded at 67.93 US cents at 8am in Wellington from 67.92 cents at the New York close, and up from 67.73 cents on Friday. The trade-weighted index increased to 71.90 from 71.77 on Friday.
The currencies of commodity producing countries, such as the kiwi and the Aussie, gained as investor optimism was bolstered by a 6.6 percent increase in oil prices amid speculation that the Organization of the Petroleum Exporting Countries and other major oil producers may agree to freeze production when they meet in Doha, Qatar on April 17.
However, while some countries have tentatively agreed to freeze production, that may be contingent on a similar commitment from Iran which isn't expected to agree.
