NZGD2000 Meridional Circuits

The Cadastral Survey Rules 2021 require surveyors to carry out surveys in terms of one of the NZGD2000 Transverse Mercator 2000 meridional circuit projections. The spatial extents of the circuits are shown in the figure below.

These boundaries are also available through the LINZ Data Service.

Learn more about Cadastral Survey Rules implementation, or access the Cadastral Survey Rules 2021 on the New Zealand legislation website
