Barry Kloogh's wife has spoken publicly about her husband's theft for the first time, saying she had been "destroyed" by his offending.
Kloogh is serving a prison term for stealing millions of dollars from dozens of clients through a Ponzi scheme.
His wife Svetlana Spectra, an artist, is about to open a gallery in Mosgiel.
A post advertising her venture on social media attracted an angry reaction from readers, many of whom raised the subject of her husband's criminal activity.
Spectra said it was correct that her husband had stolen millions.
"When this happened the news almost killed me," she posted.
"I lost everything, like many of those people.
"I lost my dreams, money, family, my husband."
She said because of her husband's name she had been unable to find work, and that art was the only thing that had kept her going.
"You don't need to know what I was going through, but instead of seating [sic] and to be sorry for myself I found the strength to do what I'm good in to support my family."
Spectra posted her message on Tuesday, and has not responded to questions or comments from other group members.
Meanwhile, families who had their life savings stolen by Kloogh plan to appeal to the Government to pay back the millions of dollars taken from them.
Kloogh, who plundered an estimated $15 million from about 170 clients, was sentenced to eight years and 10 months in prison, after pleading guilty to 11 charges in the Dunedin District Court last year.
The last liquidator's report into Kloogh's insolvent companies said there was little money available to repay investors, who had been promised their money was going into main street banks or investment funds.
Instead, the money was stolen by Kloogh as part of a Ponzi scheme he had run for many years.
Lawyer Geoff Mirkin, who is part of a professional group which has advised Kloogh's victims at no charge, said the Government had failed to put proper safeguards in place to protect investors, despite having claimed it was going to do so in several discussion documents concerning law reform of the financial advice sector.
"The Government has let down this group of people.
"The Government should write out a cheque."
The ACC system protected people who had had an accident or who had been the victim of violent crime, consumer law protected the buyers of shoddy products, and bank deposits were guaranteed, Mirkin said.
However, customers of a financial adviser accredited under government-ordered regulations, as Kloogh was, had no legal protection.
"We are two years down the track.
"We still don't know whether any third parties are liable for regulatory breaches, and so who then takes responsibility?
"It has to be the Government."
In 2010, the Government paid $1.775 billion to take control of failed moneylender South Canterbury Finance and pay back its investors and debenture holders.
Mirkin said although it was debatable legally whether the Government had to act similarly to recompense Kloogh's clients, they had been the victims of plain theft rather than failed investments.
"There are certainly moral grounds to act ...
"I think that Prime Minister Jacinda Ardern is a very ethical, highly moral person, and I don't think she needs to look for legal grounds."
Yesterday was the second anniversary of the death of Chris Churcher, who, when he was gravely ill, was promised by Kloogh that his family would be looked after.
Four days later, Kloogh was raided by police and the Serious Fraud Office.
Chris Churcher's wife, Karyn Churcher, said she continued to tell the story of how her family had about $700,000 taken from them as a warning to others, and also to lobby for changes to the financial advice regime.
"If nothing changes, if we can't have positive change, then what's the point in telling my story and making other people aware of it?" she said.
"I have to keep hope that there is actually some accountability somewhere along the way."
Both Mirkin and Churcher want to see a fidelity fund and an audit regime introduced for financial advisers.
"The Government has promised changes since the South Canterbury Finance collapse in 2010 and the David Ross Ponzi," she said.
"If these changes had happened, our family would not be in this position."
A spokesman for Ardern said she would not respond until after she had heard from the affected investors.
