The New Zealand dollar rose more than one US cent overnight as equity markets surged in response to statements by German Chancellor Angela Merkel and French President Nicholas Sarkozy even though they did not detail a plan to resolve the European debt crisis.
The kiwi dollar was at 78.25 US cents at 8am from 77.28 US cents at 5pm on Monday and traded as high as 78.52 US cents overnight.
That put it near the top of a range analysts set for a week in which they expected investors to be focused on the pathway to resolution of European sovereign debt crisis.
The leaders of Germany and France on Sunday set a tight deadline for a comprehensive plan to tackle the euro zone financial crisis that undermined global markets last week.
While investors still don't know if Greece will default or how affected banks will be recapitalised, the pledge to have a plan before the Group of 20 summit in Cannes from November 3 suggested unity of purpose from two large European economies.
