New Zealand Map Reference Converter (NZMapConv) is software that LINZ provides to convert map references between the old NZMS260 map series and the new NZTopo50 map series.
It can also be used for converting between New Zealand Map Grid (NZMG), New Zealand Transverse Mercator 2000 (NZTM2000), and latitude and longitude in terms of the New Zealand Geodetic Datum 1949 (NZGD1949) and the New Zealand Geodetic Datum 2000 (NZGD2000).
NZMapConv is a Windows programme designed to convert individual coordinates entered manually. It does not provide any facility for converting coordinates in files. If you need to convert batches of coordinates you can use the online coordinate converter, or, for NZMG, NZTM2000, and the latitude/longitude coordinate systems, you can download the CONCORD coordinate conversion programme.
