New Zealand Map Grid

The New Zealand Map Grid (NZMG) is a projection that is used to convert latitudes and longitudes to easting and northing coordinates used for most mapping of New Zealand. The projection is unique to New Zealand. It was designed by Dr. W. I. Reilly (1973) to minimize the scale error over the land area of the country

The "New Zealand Map Grid" projection has the following parameters:

  • Longitude of NZMG Origin

  • Latitude of NZMG Origin

  • False Easting

  • False Northing
