Some 50,000 Slingshot customers will be offered power to go along with their broadband this month as the company branches into new territory.
Vocus Group, which owns Slingshot, Flip and Orcon purchased a small power company, Switch Utilities, in December last year, with the promise of being able to offer customers internet and energy on the same bill.
Vocus chief executive Mark Callander said about 50,000 customers from the Slingshot arm of the business would be offered broadband-energy bundles over a couple of months from March 13.
"Shortly after the launch, once we've tested that everything's working as planned and we've assessed how fantastic the offer is and the uptake is, we'll extend it nationwide after that."
Pricing structures were still being finalised but Callander said they'd have to give customers a reason to take up the offer.
