New Zealand's markets regulator has fast-tracked the audit of five entities because of concerns about their compliance with laws that try stop money laundering and terrorism financing.
Money laundering is a tool for criminals to hide where the money originated from and regulations that came fully into force last June placed obligations on financial institutions to "detect and deter" these illegal practices.
The law - the Anti-Money Laundering and Countering Financing of Terrorism Act - requires businesses to try and guard against money laundering.
A number of New Zealand agencies, including the Reserve Bank and Department of Internal Affairs, are required to supervise the regime.
The law requires all relevant entities to undergo an audit of their AML/CFT programmes.
