Business accounts
The open banking regulation requires that all business accounts are supported for data access, and that all single-signatory business accounts are supported for payment initiation. Payment initiation from multi-signatory accounts is currently out of scope.
Support for business accounts from official open banking APIs is currently variable and incomplete, with none of the banks meeting all of the obligations in the open banking regulation.
MBIE has granted exemptions to all of the four major banks in relation to support for business accounts. These exemptions expire on 1 June 2026, and have the effect of reducing each bank's open banking obligations in relation to business accounts until that date. We expect that MBIE will provide updated guidance on requirements to support business accounts before 1 June 2026, and we will update this page accordingly.
The current status of business account support for each bank is listed below.
ANZ
Only business accounts that can be accessed using the ANZ goMoney mobile app are supported for data access and payment initiation. This excludes multi-signatory accounts.
The customer must have the ANZ goMoney app installed on their mobile device and be signed in to an ANZ customer account which has access to the business account in order to authorise a data access or payment initiation request.
ANZ does not currently support the business account coverage that is described in the open banking regulations. ANZ is relying on the current exemption which expires on 1 June 2026 in order to comply with the regulations in the interim.
ASB
Business accounts can only be connected for data access or payment initiation via a personal ASB customer account.
Some customers already have their business accounts linked to their personal ASB customer account for convenience. Those that don't will need to call ASB to request that their business accounts are linked to their personal account before they can connect them using open banking.
