The 72 investors Deloitte couldn't track down would have been eligible for payments totalling almost $243,000. Money not claimed will go to Inland Revenue.
FMA settled with former Hanover directors and promoters Mark Hotchin, Tipene O'Regan, Greg Muir, Bruce Gordon and Dennis Broit in 2015, including an unspecified amount from their insurer, ending a $35m civil claim first filed in the High Court in 2012.
Hanover principal Eric Watson, who wasn't a director of the companies and denied being a promoter of the offerings, was excluded.
The regulated reached the settlement saying it was a better outcome for investors than waiting even longer for a court case and possible appeals to be concluded.
The FMA had frozen Hotchin's personal assets for almost five years and given up on chasing a criminal case when filing the civil suit, which it saw at the time of having the best chance of success.
Of the 16,500 investors across Hanover Finance, Hanover Capital, and United Finance, it was initially estimated about 5,500 of them were eligible for a payout, with the $35m claim and resulting settlement covering the period between December 2007 and July 2008.
Hanover depositors have been paid 16c in the dollar, United stockholders 19c, and Hanover Capital bondholders 6.5c in the dollar.
Once the final payments are made, it will have been almost a decade since the Hanover group first froze payments when the local finance sector collapsed under the pressure of highly leveraged property developments struggling to generate enough cash to meet interest payments as credit conditions tightened.
Hanover investors got an initial payment of 6c in the dollar in 2009 in a planned five-year moratorium on interest payments, which was seen as a better alternative to receivership. After that, Hanover's directors opted for an alternative route when they realised their best-case scenario would see a 70 per cent return of investors' principal.
That led to Hanover investors agreeing to swap their $300m or so of debt for shares in Allied Farmers in 2009, after being convinced the merged loan book would create a lender of scale that would become a top 50 company.
As Allied wrote down the value of the Hanover loan in successive years, those investors had the value of their shareholdings chipped away to become virtually worthless and were diluted down even further after expected benefits of the deal failed to materialise.
In selling the merger, the debenture and noteholders were convinced the Allied shares would see Hanover secured depositors receive a total 78c in the dollar and United secured stockholders would get 90c, while subordinated noteholders and capital bondholders - who were to receive nothing under the moratorium - would get 30c in the dollar.
