Police are investigating James Lindon Graham (66) who is believed to have swindled people out of "millions of dollars" during the past two decades.
Yesterday afternoon, Detective Sergeant Mike Ryder said he had received six calls from people who had contact with Graham.
Det Sgt Ryder could not say they were all complainants as he was still working through the responses.
The calls were predominantly from the South Island.
One was from Auckland.
Graham is to appear in the Oamaru District Court on September 30, charged with using a document (computer) with intent to obtain a pecuniary advantage, obtaining a pecuniary advantage (money) and engaging in a money-laundering transaction.
He did not enter pleas when he appeared in court last month.
