The app means users can access up-to-date information about hundreds of selected travel experiences without the need for an internet connection, get pointed to nearby attractions and activities, and save and sync plans to other devices with the "Your Trip" feature.
For tourists who prefer to stay on the beaten path, TNZ has added the top 10 experiences, along with must-do experiences for 26 regions and many popular locations.
If you're halfway around the Milford Track, for example, you can use the app to plan where you want to go next before you even get back to your accommodation.
Online users can easily access comprehensive accommodation and transport booking information on newzealand.com.
The app also includes contact details and map locations for every activity and regional i-SITE centres, meaning you can still get travel the advice the old way.
The app is compatible with iPhone, iPad and Android devices.
