New Zealand Geodetic Datum 2000 (NZGD2000) is aligned with the International Terrestrial Reference Frame 1996 (ITRF96) and referenced to epoch 2000.0. However the NZGD2000 coordinates also include the deformation due to earthquakes since 2000, which have been applied as ""reverse patches"" in the NZGD2000 deformation model.
