QA for banking, where a defect is front-page news.

Core banking migrations, digital channels, payments, and open-banking APIs — tested by New Zealand’s independent QA specialists, trusted by the country’s leading financial institutions.

In banking, quality failures become regulatory events.

A failed batch run, a mis-posted ledger, an outage on payday — in financial services these aren’t bugs, they’re incidents with regulators, media, and customer trust attached. Between RBNZ expectations on operational resilience, AML/CFT obligations, and the conduct regime, the cost of shipping unverified change keeps rising. Independent QA is how banks ship change and sleep at night.

What we test

The platforms and journeys where banking risk concentrates.

Core banking migration

Ledger-level reconciliation, product migration, and parallel-run verification when replacing or upgrading the platform your bank runs on.

Payments & settlements

End-to-end payment journeys — domestic, international, card, and real-time — including failure paths, duplicates, and cut-over windows.

Digital channels

Internet and mobile banking regression, release-on-release, with accessibility built in — not bolted on.

Open banking & APIs

Conformance, security, and consent-flow testing for API ecosystems and third-party integrations.

Batch & overnight processing

The unglamorous jobs that break loudest: interest runs, statements, fees, and feeds to the GL and regulators.

Fraud, AML & screening

Verifying detection rules, watchlist screening, and case workflows do what compliance says they do.

Proven where it counts.

Resync consultants have delivered independent QA on core banking migrations and enterprise financial platforms for New Zealand institutions where failure was simply not an option. Ask us about our core banking practice.

Frequently asked questions

Why does a bank need independent QA rather than vendor testing?

Because the vendor delivering your platform has a commercial interest in declaring it ready. Independent QA gives the bank — and its regulators — evidence from a party with no stake in the go-live date. That separation is exactly what operational-resilience expectations point toward.

Can you test alongside our delivery partner without slowing them down?

Yes — that’s our standard operating model. We embed alongside the SI or vendor, test in parallel with build, and report to the bank’s own governance rather than the vendor’s.

Do you cover both legacy and modern stacks?

Yes. NZ banking runs on everything from decades-old core platforms to cloud-native channels. Our teams test the batch jobs and the APIs — and, critically, the seams between them.

Your next banking change deserves independent eyes.
