Official EPSG transformations from ITRF2014 to NZGD2000

The EPSG Geodetic Parameter Dataset defines 3 transformations between ITRF2014 (EPSG:7789) and NZGD2000 (EPSG:4959). Each applies to a specific area — pick the one whose area of use covers your data.

ITRF2014 to NZGD2000 (1)

EPSG:9100±0.03 mBest accuracy
Method:
Concatenated operation
Area of use:
New Zealand - onshore and nearshore
Scope:
Geodesy.
  1. ITRF2014 to ITRF96 (2) (null)

Frequently asked questions

How accurate is converting ITRF2014 to NZGD2000?
The most accurate official EPSG transformation between these systems is accurate to about ±0.03 m within its stated area of use. Browser-based converters approximate datum shifts with Helmert parameters; for surveying-grade work apply the official transformation in a desktop GIS.
Does my data leave the browser when I use this converter?
No. All coordinate transformations are computed locally in your browser using proj4js. The coordinates you enter are never transmitted to any server.
