The New Zealand dollar started the new week one US cent higher from Friday on optimism Europe will make progress while the United States economy shows some signs of life.
The kiwi dollar rose to 80.24 US cents at 8am from 79.31 US cents at 5pm on Friday. It is the highest level since Sept. 20.
Equity markets surged higher at the end of last week on evidence China had inflation under control and on a stronger-than-expected retail sales report for September in the US.
Positive comments from a meeting of Group of 20 finance ministers and central bank chiefs in Paris at the weekend ahead of a European Union summit this weekend also helped sentiment.
Still, Alex Sinton, senior dealer at ANZ, doubted that optimism about progress in Europe would last all of this week.
