A sophisticated scam is offering New Zealanders large sums are offered for their underperforming shares.
Fraudsters posing as being from a legitimate Japanese company, Sumitomo Mitsui Financial Corporation, have called Kiwis with attractive share offers after getting phone numbers from publicly available shareholder lists.
Such "boiler room" scams are often highly sophisticated. The name comes from the heated activity in the rented premises from which salespeople telephone their targets.
A cross-agency group, made up of the Ministry of Consumer Affairs, Department of Internal Affairs and Netsafe, was tipped off to the latest scam by a Wellington investor.
The man, who asked not to be named, told the Herald he was called on his mobile phone by a man who said he worked for Sumitomo Mitsui Financial Corporation. He said the man was highly convincing and called about seven times over two weeks in January.
