Retail Offer

Transpower New Zealand Limited (Transpower) has announced today that it is offering (Retail Offer) 5-year unsecured, unsubordinated fixed rate green bonds (Retail Green Bonds) to New Zealand retail investors and to institutional investors.

The Retail Offer is being made pursuant to the Financial Markets Conduct Act 2013 as an offer of debt securities of the same class as existing quoted debt securities. The notice required by the Financial Markets Conduct Regulations 2014 has been provided to NZX and is attached. The Retail Green Bonds are expected to be quoted on the NZX Debt Market.

The offer is for up to NZ$100,000,000 (with the ability to accept oversubscriptions at Transpower’s discretion) of Retail Green Bonds which are to mature on 31 July 2030.  Full details of the Retail Offer are set out in the attached Pricing Supplement (No. 20). 

The indicative issue margin for the Retail Green Bonds is 0.70 to 0.73 per cent per annum. The actual issue margin may be above or below the indicative issue margin range.

The Retail Offer is expected to close at 11:00am NZT on 24 July 2025.  An NZX announcement of the issue margin, interest rate and issue amount for the Retail Green Bonds is expected to be made on the same day, following the bookbuild process.  The Retail Green Bonds are expected to be issued on 31 July 2025.

The Retail Green Bonds are expected to be assigned a long-term credit rating of AA by S&P Global Ratings.

There is no public pool for the offer, with 100 per cent of the Retail Green Bonds reserved for clients of the Lead Manager, primary market participants and other approved financial intermediaries.
