Online Conversions

Coordinates can be converted between datums and projections automatically using this online utility using one of two interfaces.

Basic online conversion

This interface allows conversions between pre-selected datums and projections using default input and output parameters. This is the simplest way to convert coordinates on the LINZ website. more...

Detailed online conversion

This interface enables users to choose from a wider range of datums, projections and height systems. It also allows a variety of input and output formats (including bulk options) that are more suited to users with an understanding of coordinate and height conversions. more...

Common conversions

• WGS84 to NZMG
• NZMG to WGS84
• NZTM2000 to NZMG
• NZMG to NZTM2000
