New Zealand Continental Shelf Lambert Conformal 2000 (NZCS2000) is mapping projection used for official topographic maps produced for the entire New Zealand continental shelf. Separate projections are defined for mainland New Zealand and for its offshore islands:
There will always be some distortion coordinates are converted from a curved surface, such as Earth, to a flat map. Projections are used manage this distortion, and let us relate a position to a consistent coordinate in the format Easting (E), Northing (N). They also allow us to easily measure distances in metres (m).
NZCS2000 uses a Lambert conformal conic projection. This is a cone-shaped projection that is allows accurate representation of regions with substantial east-west extents.
NZCS2000 is defined in the LINZ standard LINZS25002:
