The extents of NZCS2000 are 160° E to 170° W and 25° S to 60° S.
A Lambert conformal conic projection was chosen rather than the Transverse Mercator projection because the latter becomes excessively distorted when extended over large longitudinal ranges.
NZCS2000 is formally defined in the LINZ standard LINZS25002 (Standard for New Zealand Geodetic Datum 2000 Projections). The key parameters from this standard are summarised below:
