Rules on how credit card issuers communicate with their customers over credit limit increases have been made a little more flexible in new regulations.A regulation dealing with credit limit increases, among other credit matters, was registered this week and will take effect on October 1.The regulation delivers on a Government commitment to stop credit card issuers making unsolicited credit limit increase offers. National Consumer Credit Protection Amendment Regulation 2012 (No. 1) clarifies the conditions under which credit card providers may obtain the consent of a consumer to send credit limit increase invitations.A credit card provider must gain the express consent of a consumer to be able to send a person a credit limit increase invitation. The request for consent must be by way of written communication as well. The regulation removes a limitation that the written communication need only contain a request for consent in relation to credit limit increases. Card providers can seek consent to other matters when they request consumers' permission to send credit limit increase invitations. However, each matter must be consented to separately.The regulation also deals with credit card fact-sheets and minimum repayment warnings.
