International Finance Corporation (IFC) - part of the World Bank - has mandated the ANZ and the BNZ to manage New Zealand's first green "Kauri" bond issue.
A Kauri bond is a bond denominated in New Zealand dollars that is issued by a foreign issuer.
The transaction was expected to follow in the near future, subject to market conditions, IFC said in a brief note to the New Zealand financial markets.
No other details were available. The green bond market has boomed in the past decade as fund managers move to more specialised, ethical investments.
Green bonds were created to fund projects that have positive environmental climate benefits, and proceeds from them are used to finance or refinance climate-friendly or environmental projects.
