Yes, it is possible in MapViewer 8 to convert from a coordinate system like lat/long to New Zealand Transverse Mercator. This system did not exist in MapViewer 7, but you can simulate this projection using the regular Transverse Mercator projection and entering the False Easting, False Northing, Scale, Central Scale Factor, Central Latitude and Central Longitude projection parameters.This site lists this information: http://www.linz.govt.nz/core/surveysystem/geodeticinfo/datums-projections/projections/nztm2000/index.html. According to this site, the NZTM uses the NZGD2000 datum. We did not offer any datums specific to New Zealand in MapViewer 7, but NZGD2000 is essentially coincident with the World Geodetic System 1984 (WGS84), which is the reference system that is used by GPS receivers, hence no transformation is necessary. If WGS84 is sufficient for your needs, the exact steps to convert a vector or raster file are: Golden Software's products give you the best value for your money out of any software on the market.
