You may be a bit twisted in your understanding - or I may be, I guess.
 
Volume Retention, the date visible in the vmquery output, is about how long
to keep a tape before the physical media is deemed too old to be used
further.  Once past this date, the tape won't be written to again but it can
be read if required.
 
Image Retention is about how long the catalog tracks the data on a tape.
Once an image is written to a tape, that image data is tracked in the
catalog until the image expiration time is exceeded (retention time in the
backup schedule), then the tracking for that image is deleted from the
catalog (expired) and that part of the tape is marked as reusable.  When all
images on a tape are expired, the tape is reusable for new backups, ie:
"empty".
 
The image information is retained in the catalog until the image itself
exceeds its retention period.  If you keep images for infiinite retention,
that image data is never automatically deleted from the catalog.
 
If you're vaulting copies of your catalog, then you can set a retention
period for this catalog copy.  There's not much value, IMO, in keeping these
for a long time because your on-disk catalog, and all subsequent catalog
backups, still have the tracking for the infinitely-retained images in them.
 
Note, the latest versions of NB allow you to export certain portions of your
catalog to tape and then remove them from the on-disk catalog (to keep your
catalog sizes smaller).  This makes your on-tape catalog "backup" the only
copy of that tracking info and you'd, of course, want to keep that catalog
backup for the life of your tracked data.
 
Does this cover it?

Does anyone know of a tool to track netbackup volumes past their catalog
retention? 
We have to retain  volumes indefinitely, as in forever.  Currently the
catalog retention is set for a year.  After which the volume is sent to the
scratch pool and the catalog entries purged.  There is no way of knowing
when or what is on the volume. I'm trying to avoid a manual process to
create media reports.

thanks in advance......
