Find zip code for working on newzealand

Hi Dylan, I have a way to do it but its a bit convoluted. (1) Go To Area Calculator (2) Upload the KML File on that page (3) Open the User Manu at the top right of the page and save the area (4) Come back to this page (refresh) and the same area should be available to load. (5) The area in the KML should then appear on the map.

Hi guys, can I upload a KML file or any spatial file to get more specific perimeters/boundaries rather than having to draw the area manually?

Hi guys, Any chance of a csv file linking post-codes to actual grid references?
