The New Zealand dollar advanced as some investors bet its decline made it attractive buying.
The kiwi rose to 78.74 US cents at 8am in Wellington, from 78.41 cents at 5pm yesterday. The trade-weighted index gained to 78.26 from 78.06 yesterday.
The New Zealand dollar has fallen about 11 percent from its peak in July amid concerns that falling dairy prices will weigh on farmer incomes and crimp economic growth, at the same time as increased optimism about a US recovery boosts demand for the greenback.
Some analysts say that while the longer-term trend is for the kiwi to decline, investors who follow technical charts are seeing it as attractive buying at these levels.
"It does look very much more like a technical move rather than anything fundamental," said Stuart Ive, a senior dealer of foreign exchange at OMF. "The technical pattern on the kiwi going back over the last 12 hours does suggest that we may see a little bit of further push to the upside, maybe even up to 79, where we would expect to see sellers coming into the market.
