Track the progress of the case

29 September 2021

The Banking Class Action was served on ANZ and ASB on 29 September 2021.


Due to the value of the claims, their commercial nature and the public and private importance of the issues raised, the proceeding was endorsed as a Commercial Panel case and allocated to experienced commercial Judge, Justice Venning.


As well as a statement of claim,  the Class Action plaintiffs filed an application for a series of orders (Application) including:

  • Leave to bring representative proceedings on an opt-out basis, orders relating to the notification of the claims to all class members and common fund orders (Class Issues);

  • Summary judgment (judgment on affidavit evidence, rather than after a full trial) on their own claims.

The plaintiffs requested that the Application be dealt with on a staged basis, with the Class Issues determined before the hearing of the summary judgment application.  This approach is expected to be more efficient and has the benefit of ensuring that there is clarity as to plaintiffs prior to the hearing of the summary judgment application.  The plaintiffs intention is that the summary judgment application will determine their claims against the defendants as well as key legal issues common to all class members.

28 January 2022

The plaintiffs filed an amended statement of claim and an amended version of the Application. The amendments were necessary primarily to take into account new information received from the Banks (and ASB in particular) in response requests by the plaintiffs.  

1 April 2022

ANZ and ASB filed their statements of defence and notices of opposition to the Application. 

23 May 2022

The plaintiffs’ application for notification orders was adjourned pending determination of the applications for representative orders and CFOs.

26 & 27 May 2022

The Class Issues were argued in the Auckland High Court . 

29 July 2022

Justice Venning’s judgment on Class Issues, Simons & Ors v ANZ & Anor [2022] NZHC 1836, was delivered.  The Court:

  • Granted the ASB representative plaintiffs leave to bring their proceeding against ASB on behalf of all persons who are ASB class members on an opt out basis.

  • Granted the ANZ representative plaintiffs  leave to bring their proceeding against ANZ on behalf of ANZ class members (who must have entered into their Loans after 5 June 2015) on an opt out basis.

  • Refused the ANZ representative plaintiffs leave to represent ANZ customers within the proposed class who entered into Loans with ANZ before 6 June 2015.

  • Held that the High Court has jurisdiction to make CFOs.

  • Declined to make the CFOs sought by the plaintiffs at this stage of the proceeding.


The parties each sought leave to appeal aspects of the High Court judgment that went against them.  In particular:

  • The plaintiffs sought leave to appeal points 3 and 5.

  • ASB sought leave to appeal points 1 and 4.

  • ANZ sought leave to cross appeal point 4 (but not point 2).

ANZ opposed the plaintiffs’ application to appeal point 3.  That opposition was unsuccessful and on 2 November 2022, the High Court delivered a judgment granting leave.

Leave was granted to appeal the other points unopposed. 

11 & 12 July 2023

The parties’ notices of appeal and cross appeal were filed in the Court of Appeal in late 2022. 

The appeals and cross appeals were argued in the Court of Appeal on 11 and 12 July 2023.


Shortly after the hearing, one the Judges that heard the appeal recused themselves due to a potential conflict and the Court of Appeal confirmed that the appeals will need to be reheard by a panel of three new Judges.   

What happens next:

Coming up: 23 & 24 April 2024:

The parties’ appeals and cross appeal will be reheard by the Court of Appeal in Wellington on 23 and 24 April 2024. 

After the appeals have been determined by the Court of Appeal, it is possible that there will be further appeals on the Class Issues to the Supreme Court.


A hearing for the plaintiffs’ notification and summary judgment applications will be scheduled after all appeals in relation to the Class Issues have been finally determined.  

This website will be updated to reflect developments as the Class Action progresses.
