New Zealand's new map series
In September 2009, LINZ launched a new 1:50,000 scale national paper map series, replacing the NZMS260 series.
Why did the coordinates change?
In 2000 Land Information New Zealand (LINZ) released a new national datum, New Zealand Geodetic Datum 2000 (NZGD2000). This changed the way that coordinates (latitudes/longitudes) of points in New Zealand are determined. Latitudes and longitudes in NZGD2000 are significantly different to those determined in terms of the previous datum - NZGD1949. The difference is equivalent to an approximate 200m change in position. Subsequently LINZ has also defined a new projection for national topographic mapping, the New Zealand Transverse Mercator 2000 (NZTM2000) projection, to replace the New Zealand Map Grid (NZMG) projection. Both these changes have followed extensive analysis and public consultation.
