## What are NZTM coordinates?

In 2001 Land Information New Zealand (LINZ) adopted New Zealand Transverse Mercator (NZTM or NZTM2000) as the new standard coordinate system for general mapping in New Zealand. This coordinate system is gradually replacing New Zealand Map Grid (NZMG).

**How do I find my NZTM coordinates?**

How to use

- Open the Zoom to Point tool from the tool menu.
- Select your chosen coordinate system (NZTM for this example)
- To generate coordinates based on a map location, click on the map and a yellow circle will appear – coordinates will appear in the Easting (X) and Northing (Y) boxes.

### What does NZTM stand for?

New Zealand Transverse Mercator 2000

If you were ever wondering what those NZTM Co-ordinates (New Zealand Transverse Mercator 2000 projection grid coordinates) on your GPS actually mean, you are likely not the only one.

**How do you read GPS coordinates in NZ?**

Latitude and longitude coordinates are often written as degrees, minutes, and seconds of arc as follows: 43°35′53.3″ S, 170°08′33.0″ E or as decimal degrees: -43.5981468, 170.1425128.

#### How do you read contour lines NZ?

Contour lines These lines, which join points of equal height, represent the relief in the terrain depicted. For example, if there are many contour lines close together, the terrain is steep. Contour lines that are far apart indicate land with gentle slopes.

**How do I convert coordinates from nzmg to nztm2000?**

The conversion of coordinates from New Zealand Map Grid (NZMG) to New Zealand Transverse Mercator 2000 (NZTM2000) is a three-stage process: A single set of equations to directly transform coordinates between projections is not available. This conversion process is automated on the online conversion utility and in downloadable software.

## What is the difference between nzmg and NZTM?

In NZTM the coordinates are 1570634,5180148. Note that the conversion is a complex equation, not a simple offset by a fixed amount. For mainland New Zealand you can distinguish between NZMG and NZTM coordinates, by looking at the easting part of the coordinate.

**How do I get the new NZTM maps in Topo?**

MapToaster Topo/NZ version 5, available in October, has the new NZTM maps. The maps in your handheld GPS are most likely stored in in lat/long WGS-84 coordinates, so they wont need to be updated. Modern GPS units can probably already display NZTM coordinates. Older GPS units usually have a User Grid setting that can be used.

### What does the online coordinate converter do?

The online coordinate converter converts coordinates in a range of datums, projections and height systems used in New Zealand. It also allows a variety of input and output formats. A geographic coordinate (latitude, longitude and ellipsoidal height) is in terms of a geodetic datum (eg NZGD2000, NZGD1949).
