Independent QA for Your
New Zealand Payroll.
New Zealand payroll compliance is genuinely complex — Holidays Act 2003 leave calculations, real-time PAYE payday filing to IRD, and KiwiSaver obligations all have to be right, every pay run. Resync tests payroll independently of whichever platform you run.
Payroll Errors Don’t Stay Quiet — IRD Sees Them in Real Time.
The three risk areas that cause the most payroll defects in New Zealand — and where independent testing catches them before pay day.
Holidays Act 2003 Complexity
New Zealand’s Holidays Act 2003 is widely regarded as one of the most complex leave-entitlement regimes in the world — ordinary weekly pay, average weekly earnings, and relevant daily pay calculations have driven well-documented, multi-year remediation programmes across NZ government and private-sector payrolls. Configuration errors here compound silently until someone checks.
Real-Time Payday Filing
Since payday filing became mandatory in April 2019, PAYE information goes to Inland Revenue within days of every pay run — not at year-end. Errors surface to IRD in near-real time, which means there’s far less room to catch and quietly correct a payroll defect after the fact.
Migration & Parallel-Run Risk
Payroll platform migrations and upgrades are where discrepancies hide — a new system and a legacy system rarely agree on every calculation on the first parallel run, and finding out which one is right (and why) is a specialist testing exercise, not a spot-check.
How Resync Approaches Payroll Testing
Payroll compliance risk in New Zealand doesn’t change depending on which platform runs it — Workday, SAP SuccessFactors, Dynamics 365 HR, MYOB, Datacom, iPayroll, Crystal Payroll, or an in-house system all have to get the same Holidays Act, PAYE, and KiwiSaver calculations right.
Resync tests payroll independently of the vendor — validating gross-to-net calculations, leave entitlements, statutory deductions, and payday filing accuracy against real NZ legislation, not just the platform’s own test scripts.
For migrations and upgrades specifically, we run structured parallel testing: legacy system against new system, pay run against pay run, until every discrepancy is explained — not just reconciled away.
What We Test
Our specialist team covers the full payroll testing scope — from calculation accuracy to compliance filing and platform migration.
Gross-to-Net Calculation Testing
Systematic verification that gross pay, deductions, and net pay reconcile correctly across pay frequencies, tax codes, and employment types.
Holidays Act & Leave Entitlement Testing
Annual leave, sick leave, bereavement leave, and public holiday calculations tested against Holidays Act 2003 — the single highest-risk area in NZ payroll testing.
PAYE & Payday Filing Testing
PAYE calculation and payday filing accuracy tested against IRD requirements, including employment information and deduction reporting.
KiwiSaver & Statutory Deductions Testing
Employee and employer KiwiSaver contributions, student loan deductions, and child support deductions tested for accuracy and correct reporting.
Parallel Payroll Run Testing
Legacy system run alongside new system, pay period by pay period, until every variance is identified and explained before cutover.
Payroll System Migration & Upgrade Testing
Data migration, configuration, and integration testing for payroll platform changes — protecting employee pay accuracy through the transition.
Platform Independence
We Test Whichever Payroll Platform You Run.
Not the One We’d Rather Sell You.
Resync has no payroll platform resale relationship or implementation partnership. Whether you’re on Workday, SAP SuccessFactors, Dynamics 365 HR, MYOB, Datacom, iPayroll, Crystal Payroll, or an in-house system, the compliance risk is the same — and so is our independence.

Frequently Asked Questions
What payroll, finance, and IT leaders typically ask before engaging Resync for payroll quality assurance.
Q.Why is New Zealand payroll testing so complex?
Mainly the Holidays Act 2003 — its leave-entitlement calculations (ordinary weekly pay, average weekly earnings, relevant daily pay) are widely acknowledged as some of the most complex in the world, and have driven well-documented remediation programmes across multiple NZ organisations. Add PAYE, KiwiSaver, and payday filing on top, and payroll testing needs specialist attention, not a generic regression pass.
Q.Can you test payday filing compliance to IRD?
Yes — we test that PAYE information and deduction reporting generated by your payroll system matches what’s required for payday filing to Inland Revenue, including timing and format requirements.
Q.Do you test parallel payroll runs during a system migration?
Yes — this is one of our core payroll testing services. We run your legacy and new systems side by side across multiple pay periods, reconciling every discrepancy so you know exactly what changed and why before you cut over.
Q.Can you test payroll regardless of which platform we use?
Yes. We test payroll compliance and accuracy independently of the platform — Workday, SAP, Dynamics 365, MYOB, Datacom, iPayroll, Crystal Payroll, or an in-house build. The NZ compliance requirements are the same regardless of vendor.
