Westpac will refund $7 million to 93,000 customers after reaching an agreement with the Financial Markets Authority and Commerce Commission.
This comes after Westpac did not correctly discount fees on a number of different banking packages and self-reported the issue to the FMA and Commerce Commission in December 2017.
The overall refund is made up in two parts. The bank will refund $1.28m to around 60,000 customers due to fee waivers being incorrectly applied to their tertiary or graduate banking accounts between 2007 and 2017.
In addition, the bank will issue refunds worth $5.7 million to around 30,000 customers, relating to incorrectly applied relationship rewards.
Westpac NZ acting general manager of consumer banking and wealth, Gina Dellabarca, said the issue was identified as part of a proactive review of products and services initiated by Westpac NZ.
