The New Zealand dollar rose to near a two-week high after Europe's powerhouses France and Germany reached agreement to amend the European Union treaty, allowing for tighter controls on member states to help solve the debt crisis.
The New Zealand dollar rose to 78.33 US cents overnight, from 77.76 yesterday, and was recently at 77.97 cents.
German Chancellor Angela Merkel and French President Nicolas Sarkozy met in Paris yesterday to agree on the working proposals they will put to the European Union leaders' summit this Friday to prevent a break-up of the trading bloc.
The plan will mean a rewrite of the EU treaty, which would need to be approved by all 27 EU leaders and may signal European leaders are finally committing to end the crisis.
The agreement "has stabilised risk sentiment but we don't know enough detail to make a conclusive call about what it yet means," said Dan Bell, a currency strategist at HiFX.
