Electricity company Contact Energy faces seven charges under the Fair Trading Act for allegedly misleading customers in advertising.
The Commerce Commission alleges Contact Energy made false or misleading representations in adverts that offered fuel discounts with AA Smartfuel alongside electricity plans.
The campaign offered fuel discounts "every month" to new and existing customers who signed up or stayed on certain Contact electricity plans.
The campaign ran from 4 April 2017 when Contact joined the AA Smartfuel rewards scheme to 1 July 2017, featuring across e-mails, TV, radio, newspaper, bus, digital billboard and online ads.
The Commission alleges Contact Energy made false or misleading representations about the offers, by failing to adequately disclose key information in the advertising, including that the discount was only accessible once per month, and rewards could only be redeemed on one fill, and up to a maximum of 50 litres of fuel.
