The Topo50 map series provides topographic mapping for the New Zealand mainland and Chatham Islands at 1:50,000 scale and replaces the NZMS260 series.
Topo50 is the official topographic map series used by New Zealand emergency services.
Topo50 maps use the New Zealand Geodetic Datum 2000 (NZGD2000) and the New Zealand Transverse Mercator 2000 (NZTM2000) projection. For the Chatham Islands map sheets, the Chatham Islands Transverse Mercator 2000 (CITM2000) projection is used.
