As the Customer and Product Data Act moves toward full implementation, New Zealand’s banking sector faces a period of intense preparation. The legislation introduces a statutory requirement for financial institutions to enable customers to access and share their own data with authorised third parties. While the promise of open banking offers significant benefits to consumers, it also places a range of obligations on banks, requiring technological upgrades, operational realignment, and staff training. For many institutions, compliance is not simply a legal box to tick; it represents a profound shift in how they manage information, engage with customers, and structure their services in an increasingly competitive market.
At the heart of compliance is the secure and reliable transfer of data. Banks must implement systems that allow customers to grant explicit consent for sharing account information, product details, and transaction histories. This consent must be both auditable and revocable, ensuring that customers remain in control at all times. Data transfers are required to be encrypted and routed through approved channels, with monitoring systems in place to detect anomalies or unauthorised access.
Meeting these standards demands significant investment in technology infrastructure, including secure APIs, real-time monitoring, and integration with existing core banking platforms. For institutions operating on legacy systems, this represents a major challenge, requiring careful project management and testing to avoid service disruptions.
Beyond technical readiness, banks must also address operational implications. Staff at all levels need to understand the requirements of the Act, including consent management, verification processes, and customer support procedures. Training programs must ensure that frontline employees can guide customers through new procedures and respond to queries about data sharing rights.
Risk management frameworks are also being updated to include the potential consequences of errors in data transmission, delays in consent processing, or breaches of security. Compliance officers now face the task of overseeing not only internal processes but also the interactions between banks, third-party service providers, and the regulatory authorities responsible for enforcing the legislation.
From a customer experience perspective, the introduction of open banking requires banks to rethink how they interact with clients. Customers will expect a seamless process for granting consent, viewing shared data, and revoking permissions. Any friction or confusion in these interactions can undermine confidence in the system.
As a result, institutions are investing in user-friendly digital interfaces, mobile apps, and web portals that clearly display what information is being shared, with whom, and for what purpose. Transparency is essential not only to meet regulatory requirements but also to build trust in a system that fundamentally changes the flow of personal financial information.
Banks must also prepare for competitive pressures. Once customers can easily transfer data between institutions, the barriers to switching banks are lowered. Institutions that fail to provide clear, efficient, and secure data-sharing services risk losing clients to competitors that offer a more streamlined experience.
The legislation effectively shifts some of the power to the consumer, requiring banks to differentiate themselves not only through traditional products but also through the quality and convenience of their digital and data services. Innovation becomes a key driver of retention, with institutions seeking to create value-added services, analytics, and insights that leverage shared data in ways that benefit customers.
The regulatory framework also imposes accountability standards. Banks are required to report on their compliance with the Act, including the speed and accuracy of data transfers, the handling of complaints, and the effectiveness of consent management processes. Regulators have the authority to audit systems, issue directions, and impose penalties for breaches.
This level of oversight introduces a new dimension of operational rigor, requiring institutions to maintain detailed records, implement continuous monitoring, and quickly remediate any deficiencies identified. The stakes are high, as failures in compliance can damage both reputation and customer trust, while also exposing banks to potential financial penalties.
Implementation timelines add additional pressure. Institutions must coordinate multiple workstreams simultaneously, including system upgrades, policy revisions, staff training, and customer communication campaigns. Many are conducting pilot programs to test processes, identify bottlenecks, and refine user experiences before full rollout.
Collaboration with technology vendors, third-party service providers, and industry groups has become essential to ensure that standards are met consistently and that all participants in the open banking ecosystem can interact smoothly. Delays or errors in any part of the chain could compromise the integrity of data sharing and erode confidence in the system.
According to Fintrade, compliance with the Customer and Product Data Act represents more than a regulatory requirement; it is an opportunity for banks to modernise and become more customer-focused. Institutions that successfully implement secure, transparent, and convenient data-sharing processes will gain a competitive advantage, while those that struggle may face client attrition and reputational risk.
The shift also promises broader benefits for the financial system as a whole, creating a more transparent, efficient, and innovative banking environment. Customers can make better-informed decisions, compare products with confidence, and engage more actively in managing their financial wellbeing.
As the September 2025 deadline approaches, the banking sector is in the midst of a high-stakes transformation. The combination of technical, operational, and regulatory demands ensures that only institutions that plan meticulously, invest strategically, and communicate clearly will achieve seamless compliance.
For customers, this represents a major step forward in empowerment and control over their financial lives. For banks, it is a test of agility, foresight, and commitment to meeting the expectations of a digitally enabled, data-conscious population. The successful implementation of the Act will set a new benchmark for customer experience, regulatory adherence, and innovation in New Zealand’s financial sector.
