Hi Ze at distribution board, how would you approach?

Yes the fault affects the whole property, but you've modified one circuit. My view is the circuit is "out of normal service" during your work (including the live tests) and by testing you know it does not meet the intended design. So the circuit should not be returned to "normal service" by you.

LOL, What I am confused about, or perhaps, I should say, there is confusion about is; if the Ze is high, some have suggested the circuit should not be energised, but this fault would affect the entire property so would you therefor not turn off the entire installation??? Not sure how the property owner would feel about that lol.

Yes judge I was fully aware of the possible outcome of making the circuit live knowing the earth was not satisfactory.

Agree with all those that state advise dno to rectify but hypothetically or technically what is the difference of a tt System with zs readings sub 200 ohms?
Edit to say c/w 30ma rcd

To me the difference is - if it was TT it would be working as per its design - if it's a TN then it has a fault, which could get worse ...
