History
The development of ZA-HVM, along with ZA-35, started in 1983. The main SPAAs of South Africa then were Ystervark and Cactus. While these systems were doing their jobs just fine, they were starting to show their age in comparison with systems used by other countries and the aircraft they were supposed to counter. That resulted in a competition where multiple foreign systems were studied, but South Africa decided not to buy someone else’s system and decided to make its own. Development was going smoothy, 1991 marked the debut of the first ZA-35 prototype as well as the creation of the ZA-HVM mock-up. Works on ZA-HVM we commencing at a steady pace, in 1993 the vehicle was assembled and fired its missiles fo the first time, however end of war in Angola, and resaulting form it cut in funding ultimately killed the project.

Was it real?
I am well aware that ZA-HVM is known around as mockup only thing. I thought the same thing, but after months of research i gathered enough informations to prove that it did left the mockup stage, and existed as a singular prototype.
Here is the evidence
Explanation
While at first glance this source has nothing to do with the HVM, it is not the case when we dive into it a little deeper. Article states that SAHV-3 can be fiered from Cactus, Kentron own turret and pedestal mount. At this point this also gives nothing, let me explain the connection. There are 3 known systems that could operate SAHV-3
Cactus
Pedastal mount, that is referd to this
And Kentron own turret, but do we know what it is? Yes. There is only one platform left associated with SAHV-3, and that is ZA-HVM turret
And ZA project, that is the turret mounted on the Rooikat chassis is made by none other than Kentron.
Translation
The most advanced solution, however, is the self-propelled version, whose turret was developed based on the proven ZA-35.
Instead of cannons and ammunition pods, hooks for pairs of launch containers were placed on both sides.
The turret is 2 tons lighter than the ZA-35 and it is planned to increase the number of missiles it can carry to 8.
The design of the turret itself has changed slightly, but a tracking radar has been added to the optronic system at the front, operating in the Ka-band (the Za-35 equipment may also be enriched in the future, giving it the ability to operate in bad weather conditions).
The dimensions of the radar station antenna have been slightly increased, the range of which has increased to 25 km.
The interior equipment has also been changed. The vehicle was given the name ZA-HVM and can be used to launch missiles of both types.
Work on this system is currently at an advanced stage and is expected to be completed in 3-4 years.
A full program of tests of the command-guided missile has already been carried out, as well as tests of launching the passive version at a short distance, without the use of initial radio guidance.
A prototype of a turret with 8 pods to be mounted on the chassis of a T-72 tank or a G-6 howitzer is to be ready soon, which is to additionally accommodate eight spare missiles automatically reloaded onto the launchers.

These are only the most direct one, I have 11 sources in total stating it existed and worked.
If anything is unclear, or if someone has any questions, feel free to reach out to me, i will try my best to explain everything.
