Start Creating Contours →What Are Contour Lines?
Contour lines are curves on a topographic map that connect points of equal elevation. They're essential for understanding terrain, planning hiking routes, analyzing land features, and creating accurate 3D models of the landscape.

Hiking and Tramping
Plan your routes by understanding elevation gain, identifying steep sections, and locating ridges and valleys. Download contour maps for popular trails like the Tongariro Alpine Crossing, Routeburn Track, or Milford Track.
Land Development and Planning
Analyze terrain for construction projects, assess drainage patterns, and understand site topography for building planning and resource consent applications.
Geographic Information Systems (GIS)
Import high-quality contour data directly into QGIS, ArcGIS, or other GIS software for spatial analysis, terrain modeling, and cartographic production.
3D Printing Terrain Models
Export elevation data as STL or OBJ files to create physical 3D printed models of your favorite landscapes, mountains, or regions.
About the Data Source
Our contour lines are generated from LINZ (Land Information New Zealand) LiDAR data, providing high-resolution elevation information covering the entire country. This professional-grade data ensures accuracy for both recreational and professional applications.
Frequently Asked Questions
Is this service really free?
Yes! You can generate and download contour lines for areas up to 100 km² at no cost.
What's the accuracy of the elevation data?
The LINZ LiDAR data used by NZ Elevation Tools typically has vertical accuracy of ±0.5 to 1 meter, depending on the region.
Can I use this data commercially?
Yes, under the LINZ CC BY 4.0 license, you can use the data for commercial purposes with appropriate attribution.
What if I need contour lines for a larger area?
For areas larger than 100 km², simply divide your region into multiple smaller sections and generate them separately.
