Topo50 Map Series Project

The Topo50 Map Series project will produce a 1:50,000 scale map series to replace the current Topographic NZMS260 map series. The new national map series will be launched on 23 September 2009.

The new map series will use the New Zealand Geodetic Datum 2000 (NZGD2000) and the New Zealand Transverse Mercator 2000 (NZTM2000) projection. The New National Map Series Technical Fact Sheet (pdf 425KB) provides further details.
