Retention Instrument Application

The Retention Instrument is based around the financial position of party A. As such, the party applying for the Retention Instrument needs to provide full financial disclosure of their financial position. We are aware that contractors may have separate companies that hold plant and property assets. These will need to be included in the information provided so that the insurer issuing the Retention Instrument is aware of the group financial position.

Aon is required to undertake AML verification of party A. The New Zealand Anti-Money Laundering and Countering Financing of Terrorism Act 2009 and associated regulations apply in relation to the placement of the Retention Instrument. 
We appreciate that the information requested is commercially sensitive. You can be sure that your information will be treated with the utmost confidentiality. We are happy to discuss this further with you.
