Banking API — Cross-Tasman
Single API for 100+ Australian and New Zealand Bank Connections
Connect to over 100 Australian financial institutions plus New Zealand's Big 4 banks and Kiwibank through one API. Fiskil's multi-market integration provides a unified data model and 19% addressable market expansion for trans-Tasman products.
The Challenge
Expanding from Australia to New Zealand — or vice versa — traditionally requires building separate bank connectivity, maintaining parallel infrastructure, and managing distinct institution relationships.
The Solution
Fiskil's Banking API provides access to 100+ Australian institutions and New Zealand's major banks through a single integration point, with a unified data model that eliminates cross-market engineering effort.
Capabilities
How Fiskil Helps
Comprehensive AU Coverage
Connect to over 100 Australian financial institutions including the Big 4 (CBA, NAB, ANZ, Westpac), major regionals (Macquarie, Bendigo, ING, Suncorp), credit unions, and building societies — all CDR-accredited data holders.
NZ Big 4 + Kiwibank Access
Access ANZ New Zealand, ASB Bank, Bank of New Zealand (BNZ), Westpac New Zealand, and Kiwibank (expected June 2026) through the same API. These five institutions cover approximately 90% of NZ retail banking.
Unified Data Model
Account, transaction, balance, and customer data from both markets follows a single normalised schema. AUD and NZD transactions coexist in the same data structures with consistent field names.
Institution Discovery
Query available institutions by market (AU, NZ, or both), filter by capabilities, and present users with a unified bank selection interface that covers both countries.
Implementation
How It Works
Review Institution Coverage

Update Bank Selection UI
Include NZ institutions in your bank selection interface. Fiskil provides institution metadata including name, logo, country, and supported features to populate selection screens.
Handle Multi-Currency Data

Launch in New Zealand
With the same API key and endpoints, your product now serves NZ users. No separate deployment, infrastructure, or integration is required for the NZ market.
