New Zealand is at the heart of a tangled web of shelf companies and trusts that are being used by wealthy Latin Americans to channel funds around the world, according to a report on Monday based on the so-called Panama Papers data leak.

Local media analyzed more than 61,000 documents relating to New Zealand that are part of the massive leak of offshore data from Mossack Fonseca, a Panama-based law firm. The papers have shone a spotlight on how the world's rich take advantage of offshore tax regimes.

Mossack Fonseca ramped up its interest in using New Zealand as one of its new jurisdictions in 2013, actively promoting the South Pacific nation as a good place to do business due to its tax-free status, high levels of confidentiality and legal security, according to a joint report by Radio New Zealand, TVNZ and investigative journalist Nicky Hager.
