Financial adviser Jacqui Bradley - accused of swindling 28 clients of about $15 million - blamed the bank when payments to investors were delayed, a Crown witness said.
Bradley is on trial in the Auckland District Court and has pleaded not guilty to 75 Crimes Act charges, including 58 of theft by a person in a special relationship.
The Crown alleges Bradley was "robbing Peter to pay Paul" in a Ponzi-style operation at her business, B'On Financial Services.
The accused's husband, Mike Bradley, was also facing charges but he died last year at age 63, weeks before the trial was originally due to start.
One investor, Ian Calderwood, told the court yesterday he invested $250,000 with the Bradleys in 2005.
