High-powered QC Bruce Gray has been appointed lead counsel in a lawsuit targeting penalty fees charged by New Zealand's biggest banks.
Fair Play on Fees lawyer Andrew Hooker is to file the first documents in the case against the ANZ bank at 1pm at the High Court in Auckland today.
More than 32,000 people have registered to join the lawsuit of which 13500 are individual customers of the ANZ and 1800 are small businesses.
The number of people signing up has grown by 7000 since ANZ was named last Tuesday as the first bank to be targeted.
Hooker said the filing of the court documents against the ANZ marked an important milestone in the case.
