We are using the latest map technology to create maps to accompany our listings. If there is an issue with your map not showing the right place, try a less specific address. For example, if your house is at "5 Johnsville Road, Wellington, New Zealand" and nothing comes up, try just searching for "Johnsville, Wellington, New Zealand" instead.
It may also be that the problem is not at your end - a map may have disappeared briefly due to a glitch in our geocoding service provider. Check in again a bit later to see whether it has been restored to its former glory on the site, or send us an email at email@example.com.
