The New Zealand dollar fell as the greenback strengthened following better-than-expected US housing data, boosting optimism the world's biggest economy may be recovering after a weak first quarter.
The kiwi slipped to 73.35 US cents at 8am in Wellington, from 74.20 cents at 5pm yesterday. The trade-weighted index declined to 75.94 from 76.39 yesterday.
The US dollar index, which measures the greenback against a basket of currencies, touched a two-week high of 95.474 after a report showed US housing starts reached their highest level in 7 1/2 years in April, stoking optimism the world's largest economy may be gaining momentum after a weaker first quarter.
Tonight, traders will be focused on the release of the Federal Reserve minutes to its last meeting, for clues to when it may raise interest rates.
"The kiwi is a little weaker but it's more a case of US dollar strength," said Peter Cavanaugh, client adviser at Bancorp Treasury Services.
