The New Zealand dollar gained against the greenback after a report showed US manufacturing unexpectedly contracted in May, denting speculation the Federal Reserve will end stimulus soon.
The kiwi rose to 80.98 US cents from 79.63 cents at 5pm yesterday. The trade-weighted index increased to 75.60 from 74.82 on Friday in New York.
The US Dollar Index, which measures a basket of currencies against the greenback, dropped after a report showed US manufacturing unexpectedly contracted in May, indicating the industry will provide little support for the world's largest economy. That damped suggestions the Fed will reduce its economic stimulus any time soon.
"When you have data points like this, it will remind the markets that the US still has quite a long way to go in terms of data improvement. The debate is a bit broader again," said Kymberly Martin, a strategist at Bank of New Zealand. "It reinforces the view that we have that the kiwi is not on a one way path south."
BNZ expects the New Zealand dollar to trade in its recent range of 79.50 US cents to 81.80 cents this week.
