Interislander's online booking system uses internationally accepted Secure Sockets Layer (SSL) technology to protect your personal and payment details.

Once you have chosen your desired sailing(s) and have reached either our Passenger Details or Select Sailings - Extras pages, a padlock symbol will appear on the bottom right side of your web browser, and the web URL address will now begin with "https" and not "http" (for example https//www.interislander.co.nz/passengerdetails.asp). These indicate a secure connection between your web browser and our web server.

Authentication

Double-click the padlock symbol to receive authentication from an independent third party that you are communicating directly with Interislander.

Encryption

From this point in the booking process, any data passed between your web browser and our server will be encrypted. This includes, of course, your credit card details. Double-click the padlock symbol to verify the level of encryption, and your safety.
