NZ’s Core Banking QA Authority

The leading core banking QA New Zealand partner. Billions in deposits. Millions of customers. Zero margin for error.
70+ quality engineers who’ve been inside NZ’s most critical banking transformations.

A failed core banking migration doesn’t just cost millions — it erodes customer trust, triggers regulatory scrutiny, and stalls your entire digital strategy. That’s why NZ’s leading banks rely on Resync for core banking QA in New Zealand.

We’re the independent QA partner that holds your system integrator accountable. No vendor alliances. No conflicts of interest. Just relentless, evidence-based assurance that your transformation will land.

Independent QA That Protects You

We verify the SI’s work so you don’t have to trust blindly. Thousands of automated test cases, AI-driven defect analysis, and zero vendor allegiance — we find what others won’t.

Strategy From the Trenches

Platform selection. Legacy disentanglement. Regulatory roadmaps. We’ve led strategy on NZ’s largest banking programmes — not from a slide deck, but from inside the programme.

Go-Live With Confidence

End-to-end implementation assurance from Day 1 through go-live and beyond. We embed alongside your delivery team so defects are caught in sprints — not in production with real customers.

Zero-Loss Data Migration

Millions of account records, decades of transaction history, sensitive customer data. We validate every field, every balance, every cent — end-to-end — before a single customer is touched.

Why Independence Changes Everything

Your system integrator built it. They’ll tell you it works. But who verifies their work? Resync does. As the trusted core banking QA New Zealand consultancy with no SI alliances or platform commissions, we have one incentive: making sure your transformation actually delivers.

We’ve operated inside NZ’s most high-stakes banking programmes. 70+ quality engineers. Thousands of automated test cases. AI-powered defect analytics. We don’t just find problems — we surface the systemic risks that threaten your go-live date, your regulatory standing, and your customers’ trust.

Advisory Forged in Real Programmes

Most consultancies advise from frameworks. We advise from scars. Our team has been deep inside core banking transformations at BNZ and across the NZ financial sector — navigating the real-world complexity of regulatory compliance, legacy integration, and multi-vendor coordination.

As an AoG government panel supplier, we bring the governance rigour that banks and regulators demand. Platform selection, quality maturity assessments, test strategy, programme assurance — all grounded in what actually works, not what looks good in a pitch deck.
