Banking API — Open Banking NZ
Connect to ANZ NZ, ASB, BNZ, Westpac NZ, and Kiwibank APIs
Integrate with all major New Zealand bank APIs through a single connection. Fiskil provides unified access to ANZ NZ, ASB, BNZ, Westpac NZ, and Kiwibank via Payments NZ API Centre v2.3.3 standards.
The Challenge
Connecting directly to each NZ bank requires navigating different onboarding processes, API variations, and rollout timelines.
The Solution
Fiskil abstracts the complexity of multi-bank integration behind a single, normalised API. Connect once to Fiskil and access account data from every supported NZ bank.
Capabilities
How Fiskil Helps
Unified Account Data Model
Account details, balances, and transactions from ANZ NZ, ASB, BNZ, Westpac NZ, and Kiwibank are normalised into a consistent data schema regardless of the originating bank.
Automatic Bank Onboarding
Fiskil manages the trust framework registration, MTLS certificate provisioning, and OAuth client setup with each bank, eliminating per-bank onboarding effort for you.
Graceful Bank Rollout Handling
As new banks come online (e.g., Kiwibank in June 2026), Fiskil automatically adds support without requiring changes to your integration.
Bank-Specific Error Normalisation
Fiskil translates bank-specific error codes and edge cases into consistent error responses, so your application handles errors uniformly across all banks.
