"People are more comfortable trading the Australian domestic story with the event risk from China and Crimea backing away a little bit," said Sam Tuck, senior FX strategist at ANZ Bank New Zealand in Auckland.
"The better US data is a long-term reason for the US dollar to appreciate, but in an environment of fear they got people more optimistic and willing to invest in carry trade" which helped support the kiwi dollar, he said.
Traders are looking to the Federal Open Market Committee meeting on Wednesday in Washington, when US policymakers are expected to cut monthly bond-buying to stimulate the economy by a further US$10 billion a month to US$55 billion.
New Zealand's current account deficit for the last three months of last year are due tomorrow and narrowed to $1.41 billion from $4.78 billion in the September quarter, according to a Reuters survey of economists.
ANZ's Tuck said the data won't weigh on the kiwi dollar, nor will fourth-quarter gross domestic product figures the following day, which will likely show quarterly economic growth of about 0.9 percent.
GDP is "not expected to detract to the strength of the domestic story, and it's already priced into the currency," Tuck said.
The kiwi rose to 51.45 British pence at 5pm in Wellington from 51.28 pence yesterday ahead of UK employment figures and the government budget this week.
The local currency gained to 87.16 yen from 86.62 yen yesterday, and traded at 61.44 euro cents from 61.35 cents. It declined to 94.22 Australian cents from 94.43 cents yesterday.
