DS248:
To give one example where there may be issues even with scanned QR codes:
Our local Paper Plus is also the local Post Shop. But the PO Box lobby is in a separate area, around the back of the (relatively large) building. Typically people going into the lobby will go nowhere near the entrance to the Paper Plus shop / Post Shop.
Scanning the QR code on the lobby door brings up what appears to be the identical place location as the one on the entrance to the main shop - just 'Paper Plus XXXXXXXX' where XXXXXXXX is the suburb. To be fair, I have not checked to see it the GLN's are the same (rarely go into the shop, so cannot check at this point). However, the street address given for the box lobby is that of the shop so I suspect exactly the same QR code is being used in both cases.
But I would imagine there would be a world of difference between going into the box lobby for probably less than a minute to pick up mail vs going into the shop
Still potential risks though. Occasionally someone else in the lobby at the same time, and of course touching the door handles and keypad to get in.
It may be that NZ Post haven't bothered to provide a QR code for the Box Lobby and the shop has just used one of theirs. I say this because they didn't provide one for my local Box Lobby until I complained that they were failing their legal responsibility to do so. The Box Lobby is at the back of our KiwiBank branch and has a separate street entrance to the bank. When I scan the QR code, it says "XXXXXX Box Lobby" in my diary
I'd ring up NZ Post and complain until they fix it
