I am currently working on a map of New Zealand, and would like to put 100km buffers around some of my polygons. However, whenever I try to add a CRS layer in order to do it, the shapes just disappear off my map! Or when I do manage to get them to stay, they are in degrees instead of kilometers.

Does New Zealand just not have good and usable CRS?

  • What software are you using, and what is the CRS of your source data? – Hamish Jun 17 at 22:38
  • @Hamish, I am using qgis 3.18.3 and the source data is EPSG:4167 (which puts it just over Italy on my map now) – Grace Jun 17 at 22:44
  • That won't be the right source projection if it's displaying over Italy. – Hamish Jun 17 at 22:52

You need to find out a metric projection for New Zealand. @FelixIP made a suggestion in the comments. You can look at this link about New Zealand projections.

Once you get the CRS you need to change the layer projection and maybe the project projection.
