Adding to those concerns, US factory orders also came in slightly weaker than expected and Dallas Fed president Robert Kaplan said the central bank should be patient when it comes to raising interest rates, citing the effect of tighter financial conditions on US economic growth.
"The US dollar is weaker across the board," Bank of New Zealand currency strategist Jason Wong said in a note.
"It feels like trader positioning has been a key driver of currency movements overnight, ahead of tonight's US non-farm payrolls figure."
BNZ's Wong noted the kiwi is now trading near the top of its 65.50 US cent to 67.50 cent range of the past four weeks. He said it has strong resistance at 67.50 US cents and again at 67.75 cents ahead of strong technical resistance around 68.90 cents.
"The US employment figures tonight will determine whether the New Zealand dollar breaks higher or settles back into its trading range," Wong said.
Economists polled by Reuters expect US employers to have added 190,000 jobs last month.
The New Zealand dollar rose to 91.53 Australian cents, from 91.38 cents yesterday ahead of Australian retail sales data today.
