If I double click on the kmz file, the Google Earth App I have installed on my local machine launches and successfully displays the KMZ:
However, if I use the web version of Google Earth, by click on the New button and importing the kmz file, nothing shows up.
I am not sure if there is something wrong with the kmz or if I am using the Web version of Google Earth incorrectly.
Kmz files can not be populated on web version.You need kml file to populate on web version. I tried kml and its working fine on web version.
If you don't have access to GIS tool to convert kmz file you can use online tools such as mygeodata
