Westpac NZ is refunding about NZ $7 million to around 93,000 customers after the bank did not correctly discount fees on a number of different banking packages. It self-reported the overcharging to the Financial Markets Authority (FMA) and the Commerce Commission after discovering the error, which affected customers with Westpac's Tertiary Pac, Career Starter Pac, Graduate Pac, International Student Pac, Relationship Rewards Scheme, Family Benefits and Westpac Staff Package, Bizpac, and Government Packages and Portfolio Package. The remediation process is part of an enforceable undertaking that Westpac has agreed to give the FMA and the Commerce Commission.
