Will my Garmin Edge 1030 work in New Zealand

The 1030 only comes with the maps for the device’s home region (presumably, you have a North American one).

You can buy maps from Garmin but that doesn’t include updates (AFAIK). The also might not fit on your unit without deleting the other map (you can reinstall it when done with the new map). This is a bit of a pain.

With the 1030+ and newer models, Garmin includes world-wide detailed maps (an FYI).

You can get free maps.

These, like the Garmin ones, are based on Openstreetmap data. Be sure to use the “Latin” ones (not Unicode).

There are quite a few sources for free maps. I prefer one that let you select a custom region. Custom regions make getting what you need in the smallest size. That feature is not so important for NZ (if you can get a map just for NZ).

https://garmin.bbbike.org/ is a good source (but there’s a limit to the size of custom regions).

You can, of course, try it for you neighborhood. Just be sure to disable the default map (the routing can get confused with more than one map covering the same area).

This is one of those things tha can seem a bit confusing the first time (it’s easier the next time).

You usually get a *.img file (gmapsupp.img is a common name. You can rename the file. You copy the file to the \Garmin folder on the device. 

Before you get there, you should check if the map is correctly installed. On your Edge, select your bike profile, go to the map screen and, by zooming out and moving the map to NZ, try to zoom in a city you will go. You should be able to see the street...

Good luck!

Sure, but getting a map is easy enough to do and useful to know how to do it.
