The Minimum Open Banking Implementation Plan confirms the minimum requirements and timelines that five API Providers (ANZ, ASB, BNZ, Westpac and Kiwibank) must have standardised APIs technically and operationally ready for use by the centre’s Third Parties.
The banks included in this plan collectively represents coverage of more than 90% of all consumer accounts across Aotearoa’s banking market.
This page will be updated as we publish delivery milestone dates for new versions of the standards, as an API Provider becomes ready with the standards, and with any updates to implementation dates.
