None of the residents in the 56 flats - worth up to NZ$7.5m each - has been repaid, the Mail says.
Last week at Southwark Crown Court, Copsey was jailed for eight years after being found guilty of fraud by abuse of his position.
Judge John Price blasted him for what amounted to a "gross breach of trust".
"The victims are ordinary people who lost about 30,000 pounds (NZ$58,000) each," he said.
"Neighbour has turned against neighbour. You have done all of that - you destroyed the feeling of good neighbourliness that was in the flats."
The court heard that one victim was 97 years old while another has suffered stress-related Bell's Palsy as a result of the fraud.
The Mail says that New Zealand-born Copsey "lost his own fortune in poor business dealings" before he started the scam, which ran between March 2010 and September 2012.
