Hi Lukas, Make sure that on-the-fly CRS is enabled in QGIS, then set your KMZ layer CRS to EPSG: 4326 first. Let’s see if it’s projected to the correct location.

Re: [Qgis-user] KMZ
thanks guys
but still not doing the trick
I've got everything in 4326 and the KMZ is still not sitting in the correct
location
the location is in New Zealnd but if i use 4326 it looks like it sits on the
opposite longitude

I think KMZ supports lat/long coords only... Google doesn't really understand
projections...
Make sure your KMZ layer has EPSG:4326 as its projection

Re: [Qgis-user] KMZ
Hi Lukas, It is my understanding that KMZ files should always be projected in WGS84, even if your QGIS project is in a different projection. Hopefully that solves your issue.

[Qgis-user] kmz export sed script
Hi!
As I said in a previous message, I use qgis to put together many geographic
information sources prior to downloading the data as kmz to my mobile.
That's the reason I wrote a small script to generate kmz icons from a
qgis-generated kml.
That script is a sed script, meaning it has to be processed with the
sed utility included in Linux. If you have a Windows version of qgis
bundled with Msys (such as osgeo4win), you could probably execute it from
the msys command line.
Someone could try to adapt it to python, but I don't know how to make
python scripts.
Please note: Lines are long and they could be wrapped when sendind as
email. I will use an empty line (two carriage returns) to mark new line.
---
SCRIPT 1 Generate icons from name field
This script takes a qgis-generated kml file, and adds an icon (called
Cueva.png) to every feature with a name containing Cueva or Sima,
another icon (called .Icnitas.png) to every feature with a name
containing icnita or Icnita,
another icon (called Fosil.png) to every feature with a name like
Fosil, Fósil, fosil or fósil, and another icon (called Mina.png)
to every feature with a name containing Mina.
The icons should be placed in a folder called images, and zipped along
with the modified kml file in a file with kmz extension.
The script should be invoked like this:
sed mykmlfile.kml -f kmzfromname.sed newkmlfile.kml
After that, you should use your preferred zip manager to zip together the
files. I use this:
7z -a -tzip newkmlfile.kmz newkmlfilekml images/*.png
but the syntax would be different if you use a different zip manager.

#I don't know why, but replacing folder with document allows oruxmaps put a
name (instead of a date) to this layer.
s!Folder!Document!
kmziconfromname.sed---END OF
FILE---
SCRIPT 2 - Generate icons from a custom field (not name)
This is a skeleton script. In the previous sample, I used the name to
detect the class of each feature, but my kml file has a field caled
T006_006_C that stores the actual feature class.
So I could use that field instead.
But, in order to do that, I have to read the field inside the
ExtendedData tag and, after that, put a new flag outside that tag.
Doing that with SED is tricky, because SED uses to read one line at a time.
We have to tell it to group the whole ExtendedData group in a single line.
Please notice you should adapt this script to your needs, i.e., replace
T006_006_C with the field name you want, add code to replace the !---icon
-- tags with your preferred icon, and so on.
The usage would be again,
sed mykmlfile.kml -f kmzfromfield.sed newkmlfile.kml
After that, you should use your preferred zip manager to zip together the
files. I use this:
7z -a -tzip newkmlfile.kmz newkmlfilekml images/*.png
but the syntax would be different if you use a different zip manager.

No it's not. kmz as well as kmls containing a mixture of placemarks, lines and polygons.

Re: [Qgis-user] kmz in qgis
I've found the following solution that works with my fiel, not sure if it would work in general: 1. Uncompress as if the *.kmz file were a compressed file (may be you have to rename it to *.zip in windows). You'll get a *.kml file 2. Open the *.kml file with Qgis Hope this work for other people as well. Agus maning sambale wrote: No it's not. kmz as well as kmls containing a mixture of placemarks, lines and polygons.
