Internet provider Slingshot has been warned by a consumer watchdog over a "misleading" ad campaign that promised a 10% discount for bundling broadband and electricity services.
The Commerce Commission says the promotion was likely a breach of the Fair Trading Act - which allows for a penalty of up to $600,000 per offence.
The campaign ran between July 2017 and May 2018 and in the Commission's view, was likely to mislead consumers by failing to make it clear that customers would only receive a 10% discount for bundled broadband and electricity services from Slingshot if they also paid their invoices by the due date.
Slingshot's parent company, Vocus, bought a small power retailer, Switch Utilities, in late 2016, and the following year started to offer electricity and broadband as a combined package for customers of Slingshot and its sister ISP Orcon.
It was looking to counter the success of Trustpower, which entered the broadband market with bundled deals, plus Spark, which in some areas has partnered with Genesis Energy.
