This from the French Embassy in Wellington:
"As of the 21 December 2007, New Zealand passport holders and citizens of the following countries do NOT require a visa for a stay of up to 90 days in countries that are part of the Schengen Agreement:
Andorra, Antigua and Barbuda, Argentina, Australia, Barbados, Bermudas, Brazil, Brunei, Canada, Chile, Commonwealth of the Bahamas, Costa Rica, Croatia, Dominica, East Timor, El Salvador, Grenada, Guatemala, Holy See, Honduras, Hong Kong (Special Administrative Region of the People’s Republic of China), Israel, Japan, Macao (Special Administrative Region of the People’s Republic of China), Malaysia, Mauritius, Mexico, Monaco, Nicaragua, Panama, Paraguay, Saint Kitts and Nevis, Saint Lucia, Saint Vincent and the Grenadines, Samoa, San Marino, Seychelles, Singapore, South Korea, Trinidad and Tobago, United States, Uruguay, Vanuatu, Venezuela.
Provided that travellers:
- do not intend to work in the countries listed below;
- have a passport that is valid for at least three months after their return date;
- have a return ticket,
they can travel to the following countries for up to 90 days without a visa:
Austria, Belgium, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Switzerland, Spain, and Sweden."
My guess is that if you get a return ticket now (with an estimated date of departure) that allows you to change the date, it may well cost you less than buying the second one-way ticket just a couple of weeks in advance.
We are up in Mangonui, Far North NZ, and will be walking in May & June. Isn't the anticipation and the getting ready SO much fun?
