This module explains the parts of New Zealand's Employment Relations Act 2000 that a payroll manager needs to understand and apply in daily work. The Act governs the employment relationship, employment agreements, good faith, records, collective bargaining, employee status, and ways to resolve problems. It does not provide every payroll calculation rule. Minimum wage, deductions, holidays, tax, and KiwiSaver have their own legislation. Payroll must read those rules alongside the employment agreement and the Employment Relations Act.
This training reflects official guidance available in September 2026. It is a working guide for payroll teams, not a substitute for legal advice on a disputed agreement, a worker's status, or a proposed termination.
The Act sets the framework for relationships between employers, employees, and unions. It requires written employment agreements and good faith conduct. It sets rules for individual and collective agreements, certain working arrangements, wage and time records, personal grievances, and the Employment Relations Authority.
Payroll's job is to turn an agreed employment relationship into accurate and traceable payment. An incorrect employee classification, outdated agreement, unapproved pay change, or missing hours record can therefore create payroll risk even when the calculation engine works exactly as configured.
The Minimum Wage Act sets minimum wage obligations. The Wages Protection Act governs deductions and payment of wages. The Holidays Act 2003 governs current holiday and leave entitlements during the transition to the Employment Leave Act 2026. Tax and KiwiSaver obligations arise under separate legislation. A contract cannot remove minimum legal rights. When different rules interact, record the source of each rule rather than treating one law or the payroll system as the full answer.
For each employee, ask: What is the legal relationship? Which agreement applies? What are the current terms and effective dates? What hours and earnings actually occurred? Which statutory minimums apply? Can we show the calculation and the approval trail?
Employers, employees, and unions must deal with one another in good faith. In broad terms, this means being active and constructive, responsive and communicative, and not misleading or deceptive. Significant decisions that may adversely affect an employee can require information sharing and a real opportunity to comment, subject to the Act's exceptions. HR and legal advisers should lead consultation on such decisions.
For payroll, good faith means explaining pay issues clearly, responding to reasonable questions, correcting known errors, and avoiding hidden changes to rates or agreed hours. A technically correct payslip can still be part of a poor process if the employer has not explained a change or has ignored a genuine dispute.
Do not quietly choose the cheaper interpretation. Compare the signed agreement, any collective agreement, later signed variations, policy incorporated into the agreement, and established practice. Record the ambiguity, identify affected employees and pay periods, and ask HR or legal advisers for an interpretation. Preserve the current and proposed calculations so the decision can be reviewed.
A manager tells payroll to remove an allowance next payday because the department no longer has a budget for it. The allowance is written into the employee's agreement. Payroll should not remove it on that instruction alone. Ask HR to establish whether the entitlement can be changed, whether the employee has agreed, and the effective date. Document the decision before changing the payroll rule.
Employees and independent contractors have different legal arrangements. An employee normally belongs in payroll with employment entitlements, PAYE and the relevant records. A contractor generally invoices under a contract for services and is not covered by most employee entitlements, although some tax withholding arrangements may still apply. Calling someone a contractor in an invoice or system field does not settle their status.
The 2026 changes introduced a gateway test. If every statutory criterion is met, the person is a specified contractor. The criteria include a written agreement identifying contractor status, freedom to work for others subject to the statutory wording, a choice about when to work or a qualifying subcontracting right, an ability to decline additional work without ending the arrangement, and a reasonable opportunity to obtain independent advice before signing. If any criterion is not met, the common law assessment of the true nature of the relationship still applies. The gateway test is not retrospective for periods before 21 February 2026.
Payroll should not conduct a legal status determination alone. Flag arrangements that look like employment, ask HR and legal advisers for the signed documents and assessment, and record when any approved reclassification takes effect. A retrospective finding can affect wages, holiday and leave liabilities, tax, KiwiSaver, and records.
A person invoices every week but works fixed shifts under close supervision, cannot decline work, uses the employer's equipment, and performs the same continuing role as employees. These facts do not prove status by themselves, but they require a documented review. Never use the contractor code solely because a hiring manager requested it.
Every employee must have a written employment agreement. It should identify the parties, work, place of work, agreed hours or an indication of them, pay or how pay will be calculated, and other mandatory terms, including a process for resolving employment relationship problems. The exact terms depend on the arrangement. Payroll needs the final agreement, not only a recruitment offer or an unsigned draft.
Check base rate or salary, pay frequency, ordinary hours, guaranteed hours, start and finish arrangements, overtime, allowances, commission or bonus terms, availability, shift cancellation, notice, deductions where relevant, and any provisions that affect leave or final pay. Some items may be governed by a separate approved plan or policy. Identify whether that document is part of the agreement and retain the applicable version.
Since 30 March 2025, employers must keep a copy of each employee's agreement and have easy access to it. If an employee asks for a copy, the employer must produce or provide it within seven working days. Payroll should be able to locate the current agreement, prior versions, signed variations, and effective dates without relying on one person's inbox.
Maintain a controlled register with employee ID, agreement type, document version, signature date, effective date, pay rate, hours pattern, collective coverage if applicable, and owner of outstanding questions. Do not overwrite history when a new rate or role begins. The agreement version used for a historical pay period must remain identifiable.
Confirm whether the worker is an employee, which agreement applies, when employment starts, the correct legal name and employee ID, agreed hours, rate and pay frequency, manager, cost centre, and approved bank and tax details. Check that any allowance or other term has a clear calculation method. If the agreement is missing or inconsistent, escalate immediately and protect the employee's entitlement to be paid for work performed.
A signed offer says $32 an hour, while the final agreement says $34 an hour from the first day. The HR master file still shows $32. Payroll should hold the discrepancy for urgent confirmation against the executed agreement and approved variation, correct the master data, calculate any shortfall, and keep the source and approval.
A collective employment agreement covers employees within its coverage clause who are union members and bound by the agreement. Payroll needs the correct collective, classification, step, rate schedule, allowances, effective dates, and any individual terms that validly apply. Do not assume that every person doing similar work is on the same agreement.
Maintain a change process for union membership information and classification changes. Union membership is sensitive information and should be handled with appropriate access. Payroll should not infer membership from an employee's role or from another worker's terms.
From 21 February 2026, a new employee is no longer required to start on the collective agreement's terms for the first 30 days. A new employee may agree to an individual agreement from day one or join the collective. Employers still have obligations to give information that helps new employees decide about union membership. Special rules can apply where more than one collective covers the work. HR should own the onboarding choice and provide payroll with the approved agreement and effective date.
When a collective is settled, do not apply a headline percentage to everyone. Confirm the ratified text, covered population, classifications, rate tables, effective dates, back pay method, allowances, and treatment of employees who changed role or left during the period. Reconcile the employee list and independently check a sample of complex calculations before release.
A collective rate rises on 1 July but payroll receives the signed schedule in August. Back pay may cross several pay periods and include a person who moved classifications on 15 July. Split the calculation at both effective dates. Preserve the old rates, new rates, hours, and approval for each segment.
Working hours are agreed in the employment agreement. Compare guaranteed hours, the days and times of work, roster flexibility, and actual practice. A system default of 40 hours cannot replace a 37.5 hour agreement. If the pattern changes, obtain an authorised variation where required and update payroll with a clear effective date.
Availability provisions and shift cancellation rules have specific statutory requirements. A manager cannot assume that a clause saying 'other hours as required' gives unlimited access to unpaid availability. Payroll should identify the applicable agreement clause, compensation or cancellation provision where relevant, actual notice and hours, and refer disputed interpretations to HR or legal advisers.
An internal approval rule and the question of whether someone actually worked are separate. If an employee worked outside their roster, establish the facts and applicable payment. Record additional hours for salaried employees where needed to show minimum wage compliance. Do not delete hours to make the timesheet match the agreement.
The employer must keep complete and accurate wage and time records. These include the employee's identity, start and end dates, type of agreement, kind of work, days and hours worked, pay for those hours, wages paid each period, and how wages were calculated. Where hours and pay are genuinely usual and agreed, the official guidance allows a statement of usual hours and pay in an agreement, roster, or other normal employment record; extra hours still need to be recorded where required, including to demonstrate a salaried employee receives at least minimum wage.
Holiday and leave records have separate requirements under the Holidays Act. A clocking system, roster, and payroll output may together provide the evidence, but check that the complete record can actually be reconstructed for each employee and period.
Keep wage and time records and holiday and leave records for six years, including after an employee leaves. Paper or electronic records are acceptable if accessible. Preserve historical rates, agreements, timesheets, corrections, and calculations needed to explain a historical payment. If a Labour Inspector requires records, the employer must provide them within the applicable statutory timeframe; the official guidance states ten working days if they cannot be supplied immediately.
An employee who forgets a timesheet must still be paid. Talk to the employee, establish what work occurred, obtain manager confirmation, and correct the record. A timesheet policy is a control, not a reason to withhold earned wages.
Select employees from different pay groups, including salaried, variable hour, casual, collective, and recent leavers. Trace agreement to master data, roster or timesheet to paid hours, pay codes to the calculation, and final amount to the employee record. Record exceptions, owners, corrections, and root cause.
A manager email can notify payroll of a change, but it does not by itself prove that the parties agreed to amend a contractual entitlement. Require the authorised source, the effective date, and evidence that any necessary agreement or consultation occurred. HR should decide whether a change needs a signed variation or another process.
For a prospective change, check the effective date and test the first pay. For a retrospective change, calculate the periods and employees affected, compare what was paid with what was due, review knock-on effects for leave or other entitlements, and document the correction. A rate correction may affect overtime, allowances, holiday pay and final pay calculations under other legislation.
Escalate a unilateral reduction in rate, removal of a recurring allowance, unexplained change in guaranteed hours, inconsistent collective classification, unpaid work, request to recode an employee as a contractor, or request to backdate a signed variation. Do not implement a disputed reduction while assuming HR will resolve it later.
Employees may make formal requests for flexible working arrangements under the Act. The employer must consider a request in good faith and respond in writing within one month. HR or the manager owns the decision. Payroll should check whether an approved change affects hours, work pattern, pay, leave calculations, cost centre, or a public holiday otherwise working day assessment. Obtain the approved start and end dates before changing payroll.
Employment changes during restructuring can affect job, rate, hours, allowances, continuity of service, final pay, and responsibility for liabilities. The Act includes employee protection rules for certain transfers and special provisions for specified employees. Payroll must not assume that every business sale has the same treatment. Ask HR and legal advisers for a written transition instruction covering employee population, employer entity, effective date, continuity, balances, deductions, and records. Reconcile both the old and new payroll populations.
A contract for services changes provider on 1 November. The operations team asks payroll to terminate everyone on 31 October and rehire them on 1 November. Pause and obtain the HR/legal transfer assessment first. Some employees may have statutory transfer rights and continuity that a simple termination and rehire would misstate.
HR or an authorised manager establishes the lawful termination reason, notice and dates. Payroll confirms the agreement and approved instructions, last day worked, notice or payment in lieu, outstanding earnings, deductions, and final leave payment under applicable law. Preserve the calculation and communication record. A system termination date should never be chosen simply to make a pay run close.
Most personal grievances must generally be raised within 90 days. A personal grievance concerning sexual harassment generally has a 12 month notification period. Exceptions and special circumstances can apply. Payroll should pass any complaint about underpayment, unexplained changes, disadvantage, or dismissal to HR promptly, retain the relevant records, and avoid giving the employee an unsupported legal conclusion.
A new rule generally limits unjustified dismissal grievances, and related disadvantage grievances, for employees whose annual remuneration meets the $200,000 threshold, subject to the law's conditions, transition and written opt back in. Existing employees in qualifying circumstances had a 12 month transition to 21 February 2027. The remuneration definition includes more than base salary and excludes some benefits; payroll should provide accurate pay data to HR or legal advisers, not decide grievance rights from a base salary field alone. The rule does not remove all other grievance rights or payroll entitlements.
The 2026 amendment also changed how the Authority or Court assesses remedies when an employee's conduct contributed to a personal grievance. This is a dispute resolution matter. Payroll's practical role is to preserve accurate records and implement an authorised settlement or determination, with the correct tax treatment confirmed separately.
Case 1 Agreement and system disagree
An employee's signed agreement states $80,000 a year, effective 1 April. Payroll shows $76,000 because an earlier offer was loaded. The discrepancy is found in September. Calculate each affected period from 1 April, including any related entitlements, obtain independent review, pay the correction promptly, and preserve the agreement, old and new rates, calculations and employee communication. Investigate why the final agreement never reached payroll.
Case 2 Contractor classification
A person has invoiced monthly since March. They work fixed hours under a manager and cannot turn down shifts. The hiring manager asks payroll to add them as a contractor for another year. Escalate for a documented status review. Separate the pre 21 February 2026 period from the later period for any legal assessment. Do not assume the gateway test validates an arrangement merely because the agreement says contractor.
Case 3 Collective back pay
A new collective is signed in August with rates effective from June. One employee joined the union in July and another moved to a higher classification in July. Confirm the agreement, coverage and each effective date. Calculate each person's entitlement by period and classification, then reconcile gross arrears and related effects before payment.
Case 4 Unapproved decrease in hours
A manager instructs payroll to reduce guaranteed hours from 40 to 30 next week because demand is low. Payroll should ask HR for the agreement and the lawful basis for the proposed change. Do not alter the contractual hours simply because a new roster was issued. Record any approved variation with its effective date
Before onboarding
Confirm worker status, agreement type and final document, pay terms, hours, classification, effective date, and owner of any unresolved question. Do not load a placeholder rate without a plan to verify it before payment.
Before each pay run
Review new starts, departures, rate changes, agreement variations, collective changes, unusual hours, manual overrides, unpaid time, and exception reports. Compare changes to signed or otherwise authorised sources. Reconcile employee count and material pay movements.
After each pay run
Keep the agreement version, input, approvals, calculations and correction history. Review pay queries and make prompt corrections. Feed recurring agreement or process issues back to HR, managers, and system owners.
Quarterly assurance
Sample agreements against payroll master data. Check collective classifications, rates and effective dates; contractor engagements; additional hours for salaried staff; records for leavers; and user access to change pay data. Report open issues with an owner, due date and affected population.
Question 1
What is the first document to inspect when a manager says the payroll rate is wrong? The current signed employment agreement and any valid later variation or applicable collective agreement. Compare their effective dates with the payroll master data.
Question 2
Does an employee lose wages if they fail to submit a timesheet? No. Establish and record the work performed, then pay correctly. Follow up on the timesheet process separately.
Question 3
Does the new contractor gateway test apply retrospectively to work before 21 February 2026? No. A historical arrangement requires the appropriate legal assessment for each period.
Question 4
Must every new employee start on collective terms for 30 days? No. That requirement was removed from 21 February 2026. HR must confirm the actual agreement and coverage for payroll.
Question 5
Can payroll decide that a $205,000 base salary automatically removes all grievance rights? No. The threshold has statutory conditions, a remuneration definition, a transition and possible written opt back in. Other grievance rights may continue. Refer the question to HR or legal advisers.
