Open banking has recently become a major topic in New Zealand’s financial sector, sparking discussions about how it could improve banking services and give consumers greater control over their financial data. While the concept has been around internationally for several years, it has only now begun to gain traction locally, with the government introducing regulations that require major banks to implement open banking systems from 1 December 2025.
At its core, open banking allows the secure sharing of financial data between banks and third-party providers with the customer’s explicit consent. This can include information about accounts, transactions, or payments, which can then be used to deliver innovative financial products and services. The technology relies on application programming interfaces (APIs)—digital tools that allow different systems to communicate safely. Payments NZ has developed three key API standards to underpin open banking in New Zealand:
1. Payment Initiation API – Enables customers to set up payments directly from their accounts through a website, app, or registered third-party provider.
2. Account Information API – Grants third-party access to specific information about a customer’s account, such as balances and transaction history.
3. Event Notification API – Notifies third parties about changes to a customer’s consent, for example, if they revoke permission for their data to be shared.
The potential benefits of open banking are significant. Commerce and Consumer Affairs Minister Scott Simpson highlighted that open banking could spur competition, make mortgage applications simpler, and provide better tools for budgeting and personal finance. By allowing third-party providers to access real-time financial data, consumers can more easily compare products, manage subscriptions, and make informed financial decisions. For instance, secure budgeting apps could automatically analyze spending patterns, track bills, and suggest ways to reach savings goals.
Small businesses stand to gain as well. With access to innovative financial management and invoicing tools, they can improve cash flow, receive payments faster, and take advantage of lower-cost solutions. Several New Zealand fintechs are already leveraging open banking to deliver such services. BNZ’s Payap and Volley offer faster, secure payment systems; Dosh and Revolut provide digital banking alternatives; and apps like SortMe and BudgetBuddie assist with personal financial management. Volley’s partnership with Givealittle demonstrates the practical benefits, making donations quick and easy via QR codes linked to banking apps.
Internationally, open banking has been used in creative ways. In Australia, Sharesies allows users to round up transactions and invest the difference. In the UK, apps like Little Birdie and Snoop help consumers manage subscriptions, track bills, and monitor spending patterns. These examples illustrate how open banking can improve financial literacy, convenience, and efficiency.
New Zealand’s new regulations ensure that customer consent is mandatory for sharing financial data, and all participating businesses must be accredited by the Ministry of Business, Innovation and Employment (MBIE). MBIE will issue a trust mark for accreditation, indicating a secure, verified provider. While open banking is generally considered safe, experts warn that consumers must remain vigilant. Fraudulent providers may attempt to gain access to sensitive information, so customers should always verify the legitimacy of services with their bank.
Consumer NZ’s Ruairi O’Shea emphasizes that open banking shifts control from banks to consumers, enabling better financial decisions and stronger competition. While New Zealand has been slower than other countries in adopting open banking, the new framework is expected to bring tangible benefits to both consumers and businesses, enhancing financial wellbeing and fostering innovation in the financial services sector.
In summary, open banking is set to transform the way New Zealanders interact with their money. By allowing secure, authorised sharing of financial data, it promises greater transparency, competition, and convenience, while also requiring users to remain cautious and informed to mitigate potential risks.
