Payroll needs to know which employee entitlements come from legislation and which come from an employment agreement or another binding arrangement. Both must be honoured, but they may have different eligibility, payment, carryover and termination rules. Mixing them into one leave balance or payment code makes it harder to apply those rules correctly and demonstrate compliance.
An employer can offer a fifth week of annual leave, extra sick leave or other benefits. The terms should clearly identify what is additional to the statutory minimum, and payroll should be involved before those terms are agreed. Separate codes and balances help payroll deliver the benefit as promised without changing the treatment of the employee’s statutory entitlement.
This article applies the Holidays Act 2003 rules currently in force. Those rules continue to apply until the new leave legislation takes effect in August 2028.
Both statutory and contractual entitlements must be honoured
Statutory minimum entitlements apply when the legal eligibility requirements are met, whether or not the employment agreement mentions them. An employer cannot trade them away for another benefit. For example, a generous salary or an extra week of leave does not excuse underpayment of statutory annual holidays.
Additional contractual entitlements arise from what the parties have agreed. A benefit may be above the legal minimum and still be legally enforceable. Calling it an “extra” does not make it optional once the employer is bound to provide it.
The practical distinction is therefore the source and terms of each entitlement. Payroll must establish the statutory requirement, read the agreement, and apply any enhancement. A payroll code is a way of implementing that decision; its label does not determine the employee’s rights.
Four weeks and eight percent are different concepts
Under section 16 of the Holidays Act, employees become entitled to at least four weeks of paid annual holidays after each 12 months of continuous employment. This is a leave entitlement measured in weeks. It is not a general statutory entitlement to accrue leave at 8% of earnings or hours. An “accrued leave” figure displayed by payroll software must not replace the legal entitlement.
The Act uses 8% of gross earnings in particular payment calculations, including relevant final-pay calculations and valid pay-as-you-go holiday pay arrangements. When an employee takes entitled annual holidays, the usual payment rule is the greater of ordinary weekly pay and average weekly earnings for the portion taken. Special rules, including those applying to some annual holidays associated with parental leave, must still be applied.
Giving a fifth week does not automatically change a statutory 8% calculation to 10%. Nor does setting an “accrual” field to 10% establish that the employee has received five weeks of leave or the correct payment. Payroll first needs to identify what that field controls: a monetary provision, leave units, pay-as-you-go payments or final pay.
For illustration, assume the correctly determined gross earnings for a particular 8% calculation are $30,000. This illustrates the percentage component only, not a complete final pay.
| Calculation | Amount |
|---|---|
| Statutory percentage component at 8% | $2,400 |
| Amount produced by applying 10% | $3,000 |
| Difference requiring an agreed basis | $600 |
The extra $600 is not automatically the value of the fifth week. The agreement might provide an extra week at a defined ordinary rate, a separate percentage payment, or another enhancement. If it already promises 10% for the relevant payment, payroll must honour that promise. The solution is to identify the statutory component and the agreed enhancement, rather than assume the additional 2% is required by the Act.
A fifth week can have its own agreed payment rules
A clearly defined fifth week can be provided as additional contractual leave with its own terms. The parties can agree that this extra leave is paid at the employee’s ordinary rate, without adopting the Holidays Act payment formula for that additional week. The statutory four weeks must remain fully protected. This approach depends on the wording and legal effect of the agreement; it cannot be imposed simply by moving an existing balance to a different code.
“Ordinary rate” must be defined. Does it mean the current base hourly rate multiplied by the agreed hours of leave? Does it include a regular allowance? How is it calculated for a salaried employee? It should not be confused with “ordinary weekly pay”, which is a statutory calculation and can include more than base wages.
Separate codes must apply separate rules
I would recommend separate codes and balances where statutory leave and additional contractual leave have different rules. The Holidays Act does not prescribe particular payroll code names. The legal requirement is to provide the correct entitlements and payments and maintain accurate records.
| Illustrative code | What payroll should track |
|---|---|
| AL_STAT | Statutory annual holidays and the applicable legal payment rules |
| AL_EXTRA | Additional contractual leave and its agreed payment and balance rules |
| SL_STAT / SL_EXTRA | Statutory sick leave separately from additional agreed sick leave |
| ALT_STAT / TOIL_CONTRACT | Statutory alternative holidays separately from contractual time off in lieu |
Different labels alone achieve little if both codes still use the same formula, expiry setting and final-pay treatment. Payroll needs separate rule settings, a clear record of which balance each absence uses, and reports that reconcile the movements. Where software cannot maintain separate balances, a controlled supporting register and checked calculations are needed until a suitable system solution is in place.
Existing combined balances should be reconciled against the agreements, entitlement history and leave taken before they are split. Do not assume that one fifth of a five-week balance is contractual leave: earlier usage, carryover and agreement changes may mean the remaining balance has a different composition.
Other benefits that need clear treatment
Additional sick leave
An employer might provide 15 days each entitlement year. For an eligible employee, payroll should identify the statutory 10 days and the additional five days. The statutory entitlement is not prorated for part-time employees and has statutory carryover protection up to the 20-day balance limit. Any separate rules for the extra five days must be supported by the agreement.
For example, the agreement could provide five extra days that expire at the end of that entitlement year, with statutory leave used first. If the employee uses eight statutory days and none of the extra days, payroll must retain the two unused statutory days under the statutory rules; it must not delete the entire seven-day combined balance. If the agreement gives more generous carryover for all 15 days, that promise must be honoured.
Additional bereavement leave
An eligible employee whose parent dies has a statutory entitlement to three days of bereavement leave. An agreement might provide five days for that event. Payroll can identify three statutory days and two additional contractual days, while applying any agreement that gives the same payment rate to all five. The statutory days must be paid at relevant daily pay, or average daily pay where permitted.
This separation matters if, for example, the two extra days have a defined base-pay rule or a different approval process. Those extra conditions cannot be applied to restrict the three statutory days. Bereavement leave is event-based; payroll should not turn the three-day entitlement into a single annual allowance.
Birthday or wellbeing leave
An employer could agree to give employees two paid wellbeing days each calendar year, paid at their current base rate and not carried forward. Record these as a separate contractual benefit, with rules for part-time staff and employees joining during the year. Taking a wellbeing day must not automatically reduce statutory annual holidays or sick leave. If an absence qualifies for statutory leave, the additional benefit must not be used to deny that entitlement.
Long service leave
Long-service leave is generally an agreed benefit rather than a statutory minimum. For example, an agreement could grant one extra week after five years of service, paid at a defined ordinary rate. Payroll needs the qualifying service date, any rules about breaks in service, the payment method and the treatment of unused leave when employment ends. A separate code prevents the system from automatically applying annual-holiday rules that the agreement did not adopt.
Enhanced public holiday pay and time off in lieu
Suppose an employee with a $30 hourly rate and no other relevant pay components works eight hours on a public holiday. Time-and-a-half gives $360. If the agreement promises double time, the payment is $480. Payroll can identify the $360 component and $120 enhancement, while still checking the statutory public-holiday calculation. The higher payment does not remove an alternative-holiday entitlement where the legal conditions are met.
A statutory alternative holiday must also remain distinct from contractual time off in lieu for overtime. Keep separate codes such as ALT_STAT and TOIL_CONTRACT. For example, an agreed three-hour overtime credit cannot be treated as the same entitlement as an alternative holiday, which is generally a whole day even if only part of the public holiday was worked. Different rules may apply when the leave is taken or employment ends.
Separate coding does not exclude payments from gross earnings
Payments for additional contractual leave will generally form part of gross earnings under the Holidays Act because the employer is required to make them. They can therefore affect statutory leave calculations even though the leave balance is separate. A contractual label does not, by itself, justify switching off inclusion in gross earnings.
Cash-up is a useful example. Up to one week of the statutory four-week annual-holiday entitlement can be cashed up each entitlement year under the statutory process. Cashing up an extra contractual week depends on the agreed terms. The statutory cash-up payment is excluded from Holidays Act gross earnings, but cashing up leave above the statutory minimum should be included. Using one undifferentiated cash-up code can therefore produce the wrong gross-earnings result.
Final pay also needs both sets of rules. Calculate the statutory holiday amounts and any additional contractual payment that is due. Include contractual payments in the statutory gross-earnings base where required.
Involve payroll before the benefit is agreed
A benefit needs terms that payroll can understand, calculate and evidence. Before it is signed off, HR or the manager proposing it should work through these questions with payroll and, where needed, the payroll provider:
- What is the statutory minimum, and exactly what is being added or improved?
- Who qualifies, when does the benefit become available, and is it recorded in weeks, days, hours or money?
- What payment formula applies, which earnings are included, and what happens when hours or pay change?
- Which balance is used first, and what are the carryover, expiry, cash-up and termination rules?
- Can the system maintain the required codes, balances, gross-earnings settings and records, and who checks any manual steps?
- Have examples been tested for part-time and variable work, leave across an anniversary, a pay change and an employee leaving?
If the system cannot deliver a proposed benefit reliably, resolve that before agreeing the wording. Options include clearer terms, different configuration or a controlled manual process. Once the benefit is binding, a system limitation does not remove the obligation to provide it. Any change to existing terms must follow the proper agreement process.
In conclusion, payroll should be able to explain each payment and balance by pointing to the relevant law or agreed term. That is why the distinction matters: employees receive their full statutory rights and the additional benefits promised to them, and payroll can show how both have been delivered.
