Mercury NZ said it had sold its smart-metering business, Metrix, to Pacific Equity Partners-controlled Australian metering company intelliHUB Group for $270 million.
The Auckland-based power generator and retailer said the sale would help to simplify the company.
As part of the deal, Mercury and IntelliHUB will enter into a long-term meter services agreement. Sale proceeds will initially be used to pay down debt, Mercury said.
Further application of the proceeds will be considered with the company's full-year results.
Chief executive Fraser Whineray said Metrix has been a strong performer, operating and branded separately from Mercury's core generation and retail activities.
