Wheelbarrow01:
The conclusion I have drawn is that the address is correct in all systems, we did install fibre in 2018, and it was likely tampered with in mid 2022 - when it was either fully or partially removed by the previous owners and/or their contractors performing the renovation, and I found a "dying gasp" alarm for the ONT in mid 2022 - this means the ONT went offline and never came back. The previous owners never contacted Chorus to advise it had been removed, or to arrange to have it reinstated. They then sold the property without any corrective action being taken.
I could use an expletive here, and as Admin/Mod it would not filter. But I will refrain.
