"For now the markets have much bigger concerns. It's a big world they are taking on," said Bancorp's Cavanaugh. "The only certainty in the short term is volatility and uncertainty."
Underpinning the local currency is the expectation New Zealand's 2.5 per cent benchmark interest rate is set to rise, increasing the yield of the nation's assets.
Traders expect 22 basis points of hikes to the benchmark rate over the next 12 months, based on the Overnight Index Swap curve. That has weakened from 29 basis points yesterday.
"The New Zealand dollar is overvalued but it's there for a very good reason," Cavanaugh said. "It could well stay overvalued for some time."
Traders will be eyeing reports out in New Zealand today for indications of how the economy is tracking.
A report today on terms of trade, a measure of how much imports can be funded by a set amount of exports, will likely show growth of 1.5 per cent in the first quarter, from a negative 1.3 per cent in the fourth quarter, according to a poll of seven by Reuters.
Meanwhile an ANZ New Zealand business outlook survey is expected to show continued strength.
The local currency dropped to 83.54 Australian cents from 83.76 yesterday. It slipped to 81.37 yen from 81.89 yen, and declined to 61.91 euro cents from 62.59 cents. It slid to 53.03 British pence from 53.57 pence.
