The New Zealand dollar rose after German Chancellor Angela Merkel provided a boost to the euro-zone, signalling her conditional support to the European Central Banks bond buying programme.
The New Zealand dollar rose as high as 81.16 US cents overnight, trading at 80.97 at 8am up from 80.59 cents at 5pm yesterday. The trade weighted index increased to 72.95 from 72.81.
Merkel reiterated her commitment to working with the ECB to resolve the region's debt crisis and to help reduce the borrowing costs of indebted nations, in her first public comment on the turmoil in over a month.
As the leader of Europe's biggest economy, Merkel has been under increased pressure to ease bailout terms and allowed shared debt, while facing domestic pressure from her coalition partners to refuse any more aid for Greece.
"Markets have taken the news at face value - it's a good news story and the New Zealand dollar has rallied," said Stuart Ive, currency strategist at HiFX.
