The New Zealand dollar pared gains as investors ask if Italy can afford to service its debt as the European sovereign debt saga continues.
The kiwi was at 79.48 US cents at 8am, down from the 79.83 cents overnight high and from 79.54 US cents at 5pm yesterday.
A rise in Italy's 10-year bond yield to 6.67 per cent, the highest in 14 years, has investors wondering if Europe's third-largest economy can afford the cost of funding its large debt.
Europe remains the main issue for financial markets. Investors are assessing if Italian Prime Minister Silvio Berlusconi can hold onto power while Greece is working to put in place a government to pass its latest bailout package and France has announced new austerity measures.
"The market is starting to fret about Italy," said Khoon Goh, head of market economics at ANZ New Zealand. "The kiwi is just following on from offshore as there is nothing in the local agenda to cause the market to react."
