One pay run, several versions of the facts
This is an illustrative composite client situation. It does not describe one identifiable client or a result achieved by Pillar.
A New Zealand employer has variable-hours staff. Managers build rosters in one app, employees record actual time in another, leave requests are approved by email, and an external provider processes payroll. An employee notices that the hours and leave balance on a payslip do not match the manager’s record.
The business cannot resolve the issue by choosing the system with the newest screen or the most familiar total. It needs to reconstruct one employee and one pay period from the underlying agreement and events, then carry any correction through every affected record.
Give every record a clear job
Start with a simple data map. The employment agreement and documented work pattern define the terms and current arrangement. The roster shows planned work. A timesheet or other attendance record shows what happened. A leave request and approval show the dates and type of leave authorised. Payroll inputs and calculation reports show what the system processed. The payslip and bank payment show what the employee was told and paid. The leave ledger shows how the balance moved.
Employment New Zealand requires employers to keep complete and accurate wages, time, holiday and leave records. Its guidance warns that an employer using payroll software should still check changes to an employee’s hours or pay. Outsourcing the calculation or storing approvals elsewhere does not remove the employer’s responsibility for the records.
Write down who enters, approves, exports, checks and corrects each data set. Include the effective date for changes in hours, work pattern, pay rate or leave arrangement. A hand-off without an owner or cut-off time is where a late roster change or approved absence can miss the payroll file.
Reconcile the pay period in a fixed order
Use the same employee identifier and pay-period dates across every system. Then compare:
- the agreement, current work pattern and pay settings;
- the planned roster and actual time worked;
- leave requested, approved and taken;
- ordinary hours, additional hours, leave hours and relevant rates in the pay run;
- gross pay, deductions, net pay and the bank payment;
- the payslip, payroll journal, payday filing and leave ledger.
A mismatch should be recorded as a specific difference, such as four approved leave hours absent from the payroll input or a changed work pattern taking effect one period late. Avoid forcing a leave balance or changing a pay code simply to make the displayed totals agree. The source event, applicable rule, original calculation, correction and approval should remain visible.
Employment New Zealand’s payroll assessment guide explains that payroll settings must reflect employees’ actual working patterns, agreements and changes. It also notes that some decisions require human judgement. The system can calculate consistently from its inputs while those inputs or settings are incomplete.
Trace leave as a ledger, not a single balance
A balance on a payslip is the end of a calculation chain. Review its opening position, each entitlement or accrual entry, leave taken, reversals and manual adjustments. Check the dates and units used. A balance held in days can drift from hours if working patterns change and the systems do not share the same effective date or conversion rule.
Keep the employee’s request and approval with the payroll evidence. Where a correction affects pay, tax reporting or a prior balance, record which periods were recalculated, which filings or journals were changed, what the employee received and who approved the correction. Confirm that the corrected closing balance became the next pay period’s opening balance.
An accounting-systems review can identify broken hand-offs and incomplete journals. Questions about a person’s legal entitlement, an employment agreement, repayment or an employment dispute may need an employment specialist or lawyer. Pillar can coordinate the accounting evidence without deciding a disputed legal right.
Prepare for 2028 in a separate test environment
The Employment Leave Act 2026 is scheduled to start on 6 August 2028. Employment New Zealand’s August 2026 guidance for payroll software providers says the current Holidays Act 2003 continues until then. Employers and providers can map data, develop changes and test scenarios, but future-law calculations should not be switched on for current pay runs.
Keep two dated rule sets in the implementation plan. The production payroll record should identify the law and settings used now. Test records for the 2028 change should be labelled, access-controlled and prevented from feeding live payslips, payments or filings.
Pillar’s Xero, payroll and accounting systems service can help map data owners, payroll hand-offs, journals and correction records. The tax and compliance service may also be relevant when a payroll correction affects PAYE or another filing.
