IRD has published its latest Unclaimed Money list.
This list is not of those owned touch refunds, but owed cash that has been left untouched for six or more years in companies such as financial institutions and insurance companies, or is an unpaid wage or salary.
After six years of trying to locate a person, a company hands over the cash to IRD under the Unclaimed Monies Act (1971). There is no time limit to when money can be claimed.
IRD has put an alphabetical list of 18,500 people owned $21 million unclaimed cash here: www.ird.govt.nz/unclaimed-money.
However, the balance - $57 million owed to 193,000 people - is listed in paper-based forms, from pre-2005, and not accessible online.
People who think they are owed money should email firstname.lastname@example.org.
The average amount unclaimed is $369, but the cash varies widely.
The largest amount owed in the list of 18,500 online is $371,664.05 owed to Mr K Nakayama.
The mysterious Mr Nakayama has now appeared in newspaper articles on IRD's Unclaimed Money list since at least 2010.
His fellow hold-outs include a Mrs S Konami, who has been owed $252,135.88 and Mr ZW Zhou, owed $230,383.37 - both also owed since at least 2010.
Others in line more money, if they come forward, are Education Minister Hekia Parata and husband Sir Wira Gardiner, who are listed as being owed $1325.12.
