Auckland, New Zealand, 10/06/2026: Wych welcomes Kiwibank’s announcement that it has become the first bank in New Zealand to roll out open banking through all its digital channels for both individual and business customers.

The announcement marks an important moment for New Zealand’s open banking ecosystem and demonstrates what can be achieved when banks, fintechs and local technology partners work together with a clear focus on customer outcomes.

Wych is proud to be Kiwibank’s open banking technology partner, providing the integration capability that connects Kiwibank with accredited third parties quickly and securely.

Kiwibank first announced its partnership with Wych in June 2025, confirming that Wych would assist in implementing open banking and support Kiwibank’s connection with accredited third parties. Kiwibank also announced at that time that it would not charge accredited third parties for standard API requests, a decision designed to remove cost barriers and encourage innovation across the market.

The latest milestone takes that commitment further. Kiwibank has now enabled open banking payments and data sharing for eligible individual and business customers through internet banking and the Kiwibank app. Kiwibank has also delivered open banking-enabled data sharing, including most of the features required by regulation, six months ahead of its regulatory deadline.


Dermot Butterfield, Founder and CEO of Wych, said the announcement demonstrated the strength of Kiwibank’s ambition and the value of a genuine partnership model.

“Kiwibank has taken a bold and practical approach to open banking. This is not just about meeting a regulatory requirement. It is about opening the door to better customer experiences, stronger fintech collaboration and more competition in financial services.” “We are proud to have supported Kiwibank on this journey. Delivering this type of capability takes commitment across both organisations, and the result is a major step forward for open banking in New Zealand.”

Open banking allows customers to securely share their banking data and initiate payments through accredited third parties, with customer consent. For individuals, this can support simpler payments, better money management and more personalised financial services. For businesses, it can enable greater automation, improved cashflow visibility, faster access to funding and more efficient reconciliation.

Wych believes the Kiwibank announcement is an important signal for the wider market.

“Open banking becomes real when customers and businesses can use it in the channels they already trust,” said Butterfield. “Kiwibank’s approach helps move the conversation from future potential to practical adoption. That is exactly what New Zealand needs as the ecosystem continues to develop.”

Wych works with data holders and data recipients across Australia and New Zealand, helping organisations deliver secure, scalable and standards-aligned open data capability. Its platform supports the infrastructure required to connect trusted parties, manage consent-driven data sharing and enable future open finance use cases.
