Prime Minister John Key is defending his vision to model New Zealand on Jersey or Switzerland after New Zealand was caught up in a global tax haven scandal.
The leak of documents from Panama-based law firm Mossack Fonesca, known as the "Panama Papers", has led to increased scrutiny of New Zealand's tax-free foreign trusts, which are reported to hold hundreds of millions of dollars.
In response, Mr Key has rejected the "tax haven" tag, saying there is no secrecy about New Zealand's trusts regime.
But his past comments on tax havens have come into sharper focus as a result of the leak.
Mr Key has talked openly about the benefits of economies which are built on offshore trusts.
