And in New Zealand it was only on September 6 that an Auckland man admitted running a $5.4 million Ponzi scheme.
Closer to home, in 2009, we have Warren Pickett - the man who ripped off a town.
Pickett ran a $20 million Ponzi scheme in the small Central Hawke's Bay community of Waipawa.
These operators typically hook in new investors by offering an "exclusive club", promising consistent short-term returns that are abnormally higher than prevailing market returns.
Such promises are attractive, but they are fools' gold.
The schemes are generally characterised by non-existent or opaque reporting and regulatory documents.
For example, the well-known Ross Asset Management scheme's reporting function consisted of an Excel spreadsheet and a heavily pixellated logo of a ram.
That scheme was $440 million at its peak.
Further afield, one of the largest Ponzi schemes in the world belonged to the now infamous Bernie Madoff of the US.
Again, the reporting was an Excel spreadsheet with a pixellated logo. That scheme was estimated at US$64.8 billion ($93b).
To put that in perspective with Ross Asset Management, as a percentage of GDP our Ross Asset Management scheme was 3.1 times larger than Bernie Madoff's scheme.
In the case of the recent prosecutions in New Zealand, the scheme operators were not on the Government's register of financial advisers.
New Zealand is not immune from financial fraud at a national or global level, as has been evidenced by these cases.
Our incidence of Ponzi schemes is somewhere in the vicinity of one a quarter.
For a significant number of investors, they are in their mid-50s or 60s when they are caught up in a Ponzi scheme.
There is no second chance because they are nearing the end of their working life, and it has a significant impact on their financial wellbeing.
The implications can be harsh.
So the message to would-be investors is simple - do your homework, seek independent advice and if it seems too good to be true, it likely is.
It's also important to check that your assets are firewalled from the operator.
The easiest way to do so is by utilising an independent custodial service.
For as little as a few cents per thousand dollars, the investments are firewalled from the adviser or fund manager and the assets are held for the sole benefit of the underlying owner.
Finally, choosing an independently assessed firm, such as a CEFEX-licensed adviser, can provide peace of mind.
An independent global assessment, CEFEX certification helps determine the trustworthiness of investment fiduciaries (investment advisory firms) and is regarded as a global standard of excellence.
