Interpol, based in Lyon, France, posted a "red notice" on its website seeking information on the whereabouts of 53-year-old Paul Robert Mora, who is suspected of facilitating and concealing fraudulent transactions worth more than €113 million ($190 million).
The 53-year-old is understood to be in New Zealand, where he has property in Christchurch.
A Police spokeswoman said they're fully aware of the Red Notice issued for the New Zealander.
She said they've been working with German authorities for some time on the matter.
Property records show Mora also co-owns a property on in the Christchurch suburb of Scarborough.
He is alleged to have acted on behalf of an investor while he worked at a large bank between 2006 and 2008.
Frankfurt prosecutors, who are handling the investigation, said Mora has "many contacts abroad, including in New Zealand, Great Britain, Switzerland, Australia and Spain".
The case against Mora is part of a broader investigation into so-called cum-ex transactions where participants would lend each other shares to collect reimbursement for taxes they hadn't paid.
European countries are estimated to have lost tens of billions of euros from those and similar transactions over the years, until a bank whistleblower alerted the media and forced authorities to clamp down on the practice.
The trial against Mora and other suspects before a court in Wiesbaden, Germany, is due to begin March 25. It was repeatedly postponed due to the coronavirus pandemic.
A related trial in Bonn last year resulted in suspended sentences for two British bankers after they agreed to provide detailed information about the fraud scheme.
The Companies Office shows that Mora still has a number of business interests in New Zealand, and is listed as the director of several Christchurch-based companies.
He went to St Bede's College and Canterbury University.
