As open banking takes shape in New Zealand, KiwiSaver providers are standing at the edge of a quiet revolution. By securely accessing consented banking data through APIs, they can finally see a more complete picture of their members’ financial lives — not just contributions and balances, but day-to-day income, expenses, and saving patterns.
This deeper visibility opens the door to more personalised advice, smarter engagement, and stronger retention.
The new data advantage
Traditionally, KiwiSaver providers have operated with limited insight into members’ broader financial situations. Contribution rates and balances tell only part of the story. Open banking changes that by providing access – with consent – to verified, real-time banking data.
This means providers can identify when members are under-saving, detect financial stress early, or recommend contribution increases when income rises.
Advice becomes dynamic and responsive rather than static and periodic.
Members experience guidance that reflects their real circumstances, building trust and engagement.
From advice to ongoing support
KiwiSaver advice has long been a “moment in time” process – members receive a plan and rarely update it unless something major changes.
Imagine an AI system that monitors incoming data (income patterns, spending shifts, account changes) and flags when an adviser should reach out or when automated guidance could help. Instead of generic reviews, members receive timely prompts like:
- “Your income just increased; you could reach your retirement goal earlier by raising contributions.”
This type of proactive engagement transforms advice into a continuous relationship rather than a transaction.
Retention through relevance
The KiwiSaver market is now largely driven by transfers, not new sign-ups. Retaining members has become as important as acquiring them. Open banking provides the data edge to do this effectively.
Members are more likely to stay with a provider that feels responsive and personalised.
When communication reflects their real financial behaviour, rather than generic newsletters or static dashboards, it builds loyalty. Over time, this personal connection can reduce churn and increase lifetime value.
The role of AI
AI amplifies what open banking enables. With access to richer transaction data, AI can help identify members who may be under contributing and suggest practical, personalised actions to improve their savings.
For example, AI could analyse a member’s spending and detect patterns such as recurring discretionary expenses or unutilised income capacity and then recommend ways to reallocate small amounts towards retirement contributions without affecting essential spending. This shifts advice from abstract recommendations to actionable, tailored financial coaching.
AI helps provideders scale meaningful engagement across thousands of members, making advice both personal and accessible.
Challenges and Guardrails
Using open banking data responsibly is key. Providers will need strong consent frameworks, transparent communication, and systems that protect privacy and maintain trust. AI-driven insights must be explainable, compliant, and auditable.
But for those who get this right, open banking represents the foundation for a relationship built on understanding, relevance, and long-term member value.
The path forward
Open banking will do more than improve payments or data portability. For KiwiSaver providers, it can reshape the way advice is delivered – turning it from a one-off event into an ongoing, personalised service. Combined with AI, it allows providers to anticipate needs, tailor recommendations, and strengthen the bond between member and provider.
In a market where growth now depends on trust and retention, the combination of AI and open banking may prove to be a very powerful tool for KiwiSaver providers to deliver advice that truly fits the lives of their members.
