NZ Topo Maps is a free travel and navigation app developed by Rajan Fernandez. It offers offline access to topographic maps of New Zealand. The app provides direct access to Topo250 and Topo50 maps from the LINZ data service. Users can download only the maps they need and delete the ones they don't to save device storage space. The app is fast and easy to use, making navigation a breeze.

In addition to maps, NZ Topo Maps also offers information on DOC huts and campsites with the latest alerts, as well as DOC recreational hunting areas. Users can search for named locations and import GPS routes in gpx format, which can be shared with AirDrop. The app also features a distance estimator that allows users to measure distances easily on the map. Overall, NZ Topo Maps is an excellent app for hikers, campers, and anyone who needs access to topographic maps of New Zealand offline.
