The New Zealand dollar crept higher against the euro and the greenback after the International Monetary Fund proposed to top up its lending capacity and positive US data continued, boosting demand for higher-yield currencies.
The New Zealand dollar traded at 62.82 euro cents at 8.30 a.m, up from 62.79 cents at 5pm yesterday. The kiwi traded at 80.72 US cents, up from 80.24 cents.
The stronger local unit came as the International Monetary Fund announced plans to increase its lending capacity by as much as US$500 billion in an attempt to safeguard the global economy against worsening effects of Europe's debt crisis.
The fund is expected to tap oil-exporting nations China, Brazil, Russia and India to contribute to the loan after euro-region nations pledged $385 billion last year.
It plans to strike a deal at a meeting of G20 finance ministers and central banks in Mexico City this February, Bloomberg reported.
"Europe is not blowing up - these things are helping the kiwi," said Daniel Bradanovic, head of institutional sales, global markets, at HSBC.
"The kiwi has broken higher - it still has the potential for the euro to go higher."
