In July 2026, MBIE opened a consultation period with participants in New Zealand's regulated open banking system regarding payment liability and risk allocation. Akahu's response to the consultation is below.
Thank you for the opportunity to respond to the consultation paper.
In summary, our views are:
In our full response below, we provide some general comments regarding payment liability, as well as specific responses to each scenario in the consultation paper.
There are specific obligations and liability provisions in the regulation, and these add to existing payment liability rules. But we agree that the regulated system does not create a new standalone liability framework.
We also agree that the regulation does not (and should not) create card-scheme-style chargeback or liability rules. Any such liability framework could emerge as a proprietary “scheme” built on top of the underlying open banking infrastructure, but does not belong at the infrastructure level itself.
One-off payments are a way to submit details of a payment to the bank.
The customer authenticates with their bank, and authorises the payment, directly in the bank’s app or online banking.
Accredited requestors are responsible for accurately transmitting those payment details to the bank. But otherwise we think there is no material difference between an open banking payment, and the customer choosing to manually create the same payment in the bank’s app or online banking.
Enduring payment consents are similar to one-off payments described above. The accredited requestor is responsible for accurately transmitting the payment details to the bank. And it is also responsible for ensuring that the customer has authorised any payments that are initiated pursuant to that consent.
But otherwise we think there is no material difference between the open banking payment, and the customer choosing to manually create the same payment in the bank’s app or online banking.
Payments NZ started work on open banking standards in 2016. Much of the original focus was on payments, and specifically the ability to make payments to merchants.
Traces of this original focus show up in terminology in the Payments NZ standards, such as providing a “MerchantCategoryCode” and “MerchantCustomerIdentification” in a payment consent.
However the standards became functionally broader over time, acknowledging that open banking payments are relevant to other use cases such as:
We note that some terminology in the Payments NZ standards is outdated, and does not align with the objectives and requirements of the regulated open banking system. We believe that in order to enable innovation and competition, open banking payments must be unopinionated about the specific roles of each party involved in a payment. Open banking payments should be considered as a general utility to facilitate the transfer of money on behalf of the customer. This capability goes beyond the simple purchase of goods and services from a merchant.
The regulation sets out obligations that banks must comply with regarding the information that is displayed to a customer with a payment consent request.
To comply with these obligations, we think that banks should be displaying the following details on their authorisation screen:
All bank implementations currently fall short of these obligations (some of these issues were shared with MBIE in relation to ANZ, ASB, BNZ, and Westpac in our compliance issues spreadsheet on 31 March 2026):
We have raised these issues with each bank when they were first observed, but the issues have not been resolved.
We mention this because, if banks genuinely want to control liability regarding open banking payments, the starting point is to ensure that they are meeting their regulatory obligations and providing their customers with full and accurate details of the consent request.
We think there is increased risk of customer loss, fraud, and scam activity due to the non-compliant bank implementations, because customers are not shown accurate payment details. For example, if an attacker obtains the necessary credentials to create an open banking payment consent, the attacker would often be able to conceal the payee details when attempting to convince victims into making fraudulent or mistaken payments. For completeness, we are not aware of this happening, we are solely acknowledging the heightened risk.
To respond to the questions in clause 7.8 of the consultation paper: yes we consider that bank views on liability uncertainty are being used as a reason to limit and delay their compliance with the required payment functionality, and the issues they’ve raised are better understood as non-compliance with existing obligations rather than uncertainty in the framework.
There is no requirement in the open banking regulation for a bank to use the confirmation of payee (CoP) system to ensure that the payment details being displayed to the customer are accurate.
However, in our view, if a bank wants to protect itself from liability in relation to fraudulent or mistaken payments, we think it should use the CoP system to ensure that accurate information is being presented to the customer on the bank’s authorisation screen. This would align with prerequisites in the Code of Banking Practice (CoBP) that enable the bank to disclaim liability in relation to a relevant payment.
When we’ve raised this point with banks, some have pointed to wording in the CoBP that says that the customer is eligible for compensation if they "weren’t using a third-party payment service to make the payment".
Our view is that banks should not be able to apply that exclusion to open banking payments:
We mention this because, if banks genuinely want to control liability regarding open banking payments, we think they would ensure that a CoP check is used to ensure that their payment authorisation screens accurately reflect the details of the payment being authorised.
In the meantime, we have developed a payee verification system to manage our own liability and to provide protection to customers.
We agree with the strawman view.
We think that liability is clear, and there is no need for new rules.

However we think it’s important that banks comply with their obligations regarding the information that is displayed to a customer with a payment consent request (described in our general comments above).
We also think it’s important that banks use CoP to ensure accuracy of payment details being displayed on their payment authorisation screens. According to bank-owned GetVerified which operates the existing CoP service in New Zealand:
If banks genuinely want to manage liability regarding open banking payments, and provide appropriate customer protections, we think they should ensure that a CoP result is presented to customers on their payment authorisation screens.
The smallest useful fix is to enforce compliance with existing consent disclosure obligations, and to encourage banks to display CoP results on their authorisation screens.
We agree with the strawman view.

We agree with the strawman view.
However, in order to deliver the competition and innovation potential of open banking payments, we think that additional standards should be developed in order to improve the performance and reliability of open banking payments.
An important design element of open banking payments is the ability for an accredited requestor to immediately know whether the payment request has been processed successfully by the customer’s bank. Accredited requestors should receive a terminal status on a payment request within seconds, and should be able to rely on this status with certainty in order to release goods or services to the customer.
But the current bank implementations do not deliver on this design intent:
Given these issues, accredited requestors cannot use payment statuses to conclusively determine whether a payment will be settled successfully. To avoid credit risk, an accredited requestor needs to wait until the funds have settled and been reconciled before releasing the goods or services, which undermines a key attribute of open banking payments.
We recommend that additional standards are developed to ensure that:

The risks that banks have raised would be addressed by complying with their existing obligations to disclose full and accurate details on payment authorisation screens.

Thank you again for consulting on these topics. We welcome further discussion on our submissions or other matters that arise through this consultation.
