The New Zealand dollar rose to a new five-month high against the euro on speculation European banks may struggle to strengthen their balance sheets enough to meet criteria for financial aid.
The New Zealand dollar rose to 61.05 euro cents from 60.85 cents yesterday and reached a high of 61.13 cents overnight.
The currency fell to 78.13 US cents at 8am from 78.86 cents at 5pm yesterday.
The 17-nation euro weakened against most major currencies as European shares fell, led by Italy's largest bank, UniCredit which lost 17.3 per cent, following a 14.5 decrease a day earlier.
The European Banking Authority told four Italian banks they needed to boost their capital and submit their recapitalisation plans to the central bank by the established January 20 deadline.
