I have seen this Advanced Diploma previously and saw the NQF level is the same as the old BTech, wanted to see if their was any other options to obtain a Degree.
Take a look at:

An advanced Diploma is equivalent to a degree/BEng. That's the entire idea of the change to the system, to make it more equivalent/comparable, notice the level changes between MTech (8) and Masters (9), which now is the same as the normal university path.
I'm actually expecting due to this that all the technical universities ranking will go up quite a bit as before Btech was messed up a bit as people from pure vocational colleges could enter which resulted in a high drop-out rate from them as they needed to be a lot more academic for it, which reduced potential MTech students.
I've met some people at CPUT that were doing the old Btech in engineering, I think that this is the last year (after like 3 years extensions) of Btech, they've been meaning to change it since 2015. I've managed to get into the new Masters after doing a bridging course, which is probably no longer possible as the advanced diploma now exists, plus doesn't apply to you as you would still need to do Btech.
If you can manage to get into Btech instead, try and get into that instead, saves you a year, but you'd have to catch up with a bridging course if you wanted to get into masters/they'd force you into post graduate for further studies.
It all depends on what path you want to take. Most of the changes to the degrees are good though.
