The New Zealand dollar rose more than half a US cent overnight after government figures showed the most Americans since January filed for an unemployment benefit last week, while Australian job numbers grew more than forecast in March.
The kiwi gained to 82.67 US cents at 8am from 81.95 cents yesterday at 5pm. It rose to 79.20 Australian cents from 78.97 cents yesterday.
Investors eschewed the greenback after the number of people in the US filing for an unemployment benefit increased by 13,000 in the week ended April 7 to 380,000, according to the US Labor department. The median forecast in a Bloomberg survey was for 355,000.
The weaker US data helped support speculation the Federal Reserve will embark on another round of quantitative easing. Two of the Federal Reserve's top policy makers, Janet Yellen and William C. Dudley, have endorsed the central bank's 'highly accommodative' policy, which has been boosting demand for high-yielding currencies such as the kiwi.
"The Fed Reserve is trying to downplay the expectations of the market - they need low rates," said Alex Sinton, senior dealer at ANZ New Zealand. "I truly believe they won't run all the way till 2014."
