How Much Annual Leave Do You Accrue Per Week in NZ

Picture the moment your payroll app shows a little pile of annual leave building up each week — it looks like money in the bank. In New Zealand, the law actually works differently: the four-week entitlement lands on each 12-month anniversary of continuous employment (Employment New Zealand (official leave guidance)). This guide shows how to calculate the weekly equivalent for full-time, part-time and casual work, when 8% holiday pay applies instead, and what the proposed reforms could change.

Minimum annual leave after 12 months: 4 weeks (20 days) ·
Pay-as-you-go holiday pay (before 12 months): 8% of gross earnings ·
Weekly planning rate after 12 months: 0.0769 weeks per week worked ·
Proposed cash-in cap: Up to 25% of balance (not yet law)

Eight numbers, one pattern: the legal constant is 4 weeks per year, and every other figure — weekly, hourly or percentage — is a conversion from that baseline.

How do I calculate my annual leave accrual?

First, the legal truth: New Zealand does not accrue annual holidays week by week. The right to four weeks of paid annual holidays arises on each 12-month anniversary of continuous employment with the same employer (Employment New Zealand). Balances shown in payroll systems are a notional planning estimate, not the statutory mechanism.

What is the formula for weekly accrual?

• 4 weeks ÷ 52 weeks = 0.076923 weeks of annual leave per week worked (Employment New Zealand)
• 5-day week: 20 days ÷ 52 = 0.3846 working days per week
• 40-hour week: 40 × 0.076923 = 3.0769 hours per week

The formula is a simple ratio: the four-week entitlement divided by the 52 weeks in a year. Use it for budgets, rosters and personal planning, but remember that the law treats the anniversary — not the weekly drip — as the moment the entitlement exists (Employment New Zealand).

How does continuous employment affect accrual?

• The trigger is 12 months of continuous employment with the same employer (Employment New Zealand)
• Before that date, there is no statutory 4-week entitlement — even if payroll shows a running balance
• Each further 12-month anniversary adds another 4 weeks

Continuous means an unbroken employment relationship with the same employer. Start a new job and the clock begins again with the new employer; unused leave from the old job is paid out in your final pay. That is why a brand-new starter can see a small balance in week one — it is a projection, not a debt the employer owes yet.

What about part-time or irregular hours?

A part-time employee gets four weeks of annual holidays based on their own regular working week, not four full-time weeks (Employment New Zealand). Work three eight-hour days and your four weeks translate to 12 days or 96 hours, assuming that pattern remains your relevant working pattern (Employment New Zealand). For genuinely irregular or casual work, the 8% holiday pay method replaces the weekly balance idea entirely (Employment New Zealand).

The implication: understanding the difference between statutory vesting and notional accrual avoids misreading payroll balances as immediate obligations.

What is the annual leave entitlement in NZ?

New Zealand guarantees a minimum of four weeks of paid annual holidays to every employee who has completed 12 months of continuous employment with the same employer (Employment New Zealand). For someone on a standard five-day week, that means 20 working days per entitlement year (Employment New Zealand).

Who qualifies for annual leave?

• Most employees, full-time or part-time, qualify after 12 months of continuous employment
• 4 weeks is the legal minimum; an employment agreement can offer more
• Genuine casual and fixed-term-under-12-month workers can instead receive 8% holiday pay in each pay (Employment New Zealand)

The entitlement follows the employment relationship, not the number of hours. A part-timer gets four weeks of their own working week; a full-timer gets four of theirs (Employment New Zealand). The Act sets a floor, not a ceiling.

How is ‘continuous employment’ defined?

• Continuous = an unbroken employment relationship with the same employer for 12 months (Employment New Zealand)
• The 12-month clock runs per employer — a new job starts a new qualifying period
• Irregular or seasonal work may never form 12 continuous months; the 8% method covers those cases (Employment New Zealand)

Continuous employment is the gateway to the entitlement. When a worker’s engagement is genuinely intermittent — no ongoing expectation of work — the relationship may not build 12 continuous months, and holiday pay of 8% is the mechanism the Act provides instead (Employment New Zealand).

What are exceptions for casual workers?

An employer who labels an ongoing role “casual” to avoid leave obligations is exposed if the actual pattern of work looks like a continuing relationship — the Act’s protections apply to the substance of the arrangement, not just the label (Employment New Zealand).

The implication for employees: four weeks is a floor, and part-time status doesn’t shrink it. For employers, the question is whether the “casual” label matches the real pattern of work — because the law will check both.

How do I calculate my holiday pay entitlement?

Once you have annual leave, the amount you’re paid while taking it is protected by a “greater of” test: at least your ordinary weekly pay or your average weekly earnings (Employment New Zealand (annual holiday pay rules)).

What is holiday pay and how does it differ from annual leave pay?

• Annual leave pay is what you’re paid while taking your four weeks of leave
• Pay-as-you-go holiday pay is a separate 8% payment method for genuine casual or short fixed-term workers, paid with each wage packet (Employment New Zealand)
• The two systems can’t be mixed for the same employee in the same period

Annual leave is time off that is paid; 8% holiday pay is money paid instead of maintaining a leave balance. The law allows the 8% route for genuine fixed-term agreements under 12 months and for casual employees, set at a minimum of 8% of gross earnings (Employment New Zealand).

How to calculate 8% holiday pay on gross earnings?

Formula: gross earnings for the period × 0.08 ·
Example: $1,000 gross = $80 holiday pay ·
Minimum rate: 8% (contracts can pay more)

Gross earnings, broadly, is what the employee earned in the period before tax. Multiply that figure by 0.08 and pay it as a separate holiday pay line — either in each pay period or at the end of the employment if it wasn’t paid as you went (Employment New Zealand).

When is holiday paid as an extra 8% in each pay?

• For casual employees with no regular work pattern (Employment New Zealand)
• For employees on a genuine fixed-term agreement of less than 12 months (Employment New Zealand)
• Only when the arrangement genuinely matches one of those categories

When the 8% method applies, the payment shows up as an extra line on the payslip, calculated from gross earnings for that pay period. Once paid, it is the employee’s money — it does not later convert into annual leave days (Employment New Zealand).

How many days annual leave for 4 years?

On a five-day week, four weeks equals 20 working days. Let the balance run and the multiples are easy to forecast.

How much annual leave accumulates over 4 years?

That’s 16 weeks — or 80 days — of paid leave sitting on the books after four years if you take no time off. Each 12-month anniversary simply adds another four weeks to the running total (Employment New Zealand). For a part-timer on a 3-day week, the same pattern produces 12 days a year, or 48 days over four years.

Does unused leave carry over?

• Yes — unused annual leave carries over to the next entitlement year (Employment New Zealand)
• There is no statutory cap on the balance an employee can hold
• But an employer can require leave to be taken when the balance gets excessive (Employment New Zealand)

The carryover rule is generous by design: the leave is yours and an employer can’t simply cancel it. The employer’s counterweight is the ability to direct when leave is taken, with proper notice — so an ever-growing balance is not a shield against being told to take a break (Employment New Zealand).

What is the maximum leave balance limit?

No statutory cap today means the balance can grow for years if the employer tolerates it. The proposed overhaul would add a release valve: request to cash in up to 25% of the balance, rather than being limited to the narrow cash-out situations the current Act allows. The proposal is still being finalised — treat the 25% figure as a target, not a current right.

Is it better to take annual leave or have it paid out?

Annual leave is meant to be taken — that’s the law’s core assumption. But the cash value is real, and the proposed 25% cash-in rule would make this question far more common.

Tax implications of taking leave vs payout?

• Taking leave: your leave pay goes through PAYE like a normal wage payment
• Payout: the lump sum is also taxed as earnings in the pay period it’s paid
• There is no special “leave rate” — the difference is timing and cash flow, not tax treatment

From a tax perspective, both routes are ordinary earnings. The real difference is timing: leave taken now pays you while you rest; leave paid out pays you in cash when you leave or, under the proposed rules, when you ask. For most employees the PAYE treatment is the same either way.

Impact on future entitlements?

• Taking leave preserves your balance and keeps the 4-week cycle intact for the next anniversary
• Cash-out reduces the balance — and under the proposed 25% rule, you’d always keep at least 75%
• Current law does not allow every employee to cash out mid-employment; the exceptions are narrow

The biggest trap is expecting a payout the law doesn’t allow. Under the current Act, cashing in annual leave during employment is only available in limited agreement-based situations; the routine cash-out moment is your final pay when you leave (Employment New Zealand).

When is payout allowed?

• On resignation or termination: unused annual leave is paid out in your final pay (Employment New Zealand)
• Mid-employment: only where the employment agreement permits and the Act’s conditions are met
• Proposed reform: employees could request up to 25% cash-in as a general right, with the employer able to decline in some circumstances

The proposed change would make payout a normal, employee-initiated option rather than an employer-controlled exception. Until it passes, the safe assumption is that your annual leave is time off, and its cash value is realised on the way out the door — not before (Employment New Zealand).

The trade-off: leave protects your rest and your balance, and pays at the greater of ordinary weekly pay or average weekly earnings; payout gives you liquidity today but shrinks the buffer for a future break. The sensible route for most people is a mix — take most of it, and revisit the cash-in option once the new Act starts.

The implication: the tax-neutral treatment means the choice hinges on cash need vs rest, not on tax optimisation.

Taking annual leave vs cashing it out: the trade-off

A quick decision grid for the choice the reforms are about to put in front of more employees.

The pattern: leave is the better deal for wellbeing and pay certainty; payout is the better deal for cash flow. The proposed 25% rule is an attempt to give employees some of both.

How to calculate your weekly annual leave accrual: 6 steps

1. Identify your employment type. Full-time and part-time employees build toward the 4-week entitlement; genuine casual and fixed-term-under-12-month workers use 8% holiday pay (Employment New Zealand).
2. Find your 12-month anniversary. The entitlement vests on each anniversary of continuous employment with the same employer (Employment New Zealand).
3. Convert the 4 weeks to a weekly planning rate. Divide by 52: 4 ÷ 52 = 0.0769 weeks per week worked.
4. Scale to your own pattern. 5-day week: 20 ÷ 52 = 0.3846 days/week. 3-day week: 12 ÷ 52 = 0.2308 days/week. 2-day week: 8 ÷ 52 = 0.1538 days/week.
5. If you’re casual or short fixed-term, use 8% instead. Gross earnings for the pay period × 0.08 = the holiday pay to add to that pay (Employment New Zealand).
6. Treat the payslip balance as an estimate. Payroll’s “accrued” figure is notional; the legal entitlement is confirmed at the anniversary, and leave pay is the greater of ordinary weekly pay or average weekly earnings (Employment New Zealand).

If you’re a payroll professional, step 6 is the one that saves money: the gap between the notional balance and the statutory entitlement is where most leave-pay disputes start.

Timeline: how New Zealand’s annual leave rules got here

• 2003 — The Holidays Act 2003 sets the legal minimum of 4 weeks of annual holidays after 12 months of continuous employment (Employment New Zealand).
• 2024–2025 — The government announces a major overhaul of the Holidays Act, including new accrual methods, simplified holiday pay and a proposed 25% cash-in right.
• 2025 (proposed) — The new Act is expected to take effect; the exact date has not been confirmed.
• Now — Current rules apply: 8% pay-as-you-go holiday pay for genuine casual and short fixed-term roles, then 4 weeks per year after the 12-month anniversary.

The pattern to watch: the reform is moving toward making leave balances more flexible — cash-in options, simpler formulas, better records. But until the new Act starts, the old rules are the ones that count.

What’s confirmed vs what’s still unclear

What this means: the fundamentals are stable — 4 weeks, 8%, the higher-of test. The uncertainty sits in the reform’s details, so plan using current law and treat the new rules as a bonus when they land.

What the experts say

Three voices frame how New Zealand’s leave rules actually work — the regulator, the tax authority and the lawyers watching the reform.

“Annual holiday pay when leave is taken must generally be at least the greater of ordinary weekly pay and average weekly earnings.”

— Employment New Zealand (annual holiday pay rules)

“You can pay holiday pay in an employee’s regular pay instead of wages when they take annual leave as an extra 8% of their gross earnings.”

— Inland Revenue (IRD) guidance

“Employees will be able to request to cash in up to 25% of their total annual leave balance, rather than being restricted to only one week.”

— Dentons legal alert on the Holidays Act overhaul

Read together, they show the arc: annual leave is paid time off, casual work has its own 8% maths, and the reform’s headline change — the 25% cash-in — is still ahead of us.

What this means for you

New Zealand’s annual leave rule is a 4-week block that vests at each 12-month anniversary, not a drip-feed of hours — but the weekly planning number (0.0769 weeks, or about 3.08 hours for a 40-hour worker) is the figure most people search for (Employment New Zealand). The distinction matters when money changes hands: leave pay uses the higher of ordinary weekly pay or average weekly earnings, casual and short fixed-term workers get a clean 8% top-up instead, and the proposed reforms would finally let employees convert up to 25% of an unused balance into cash. For employers, the calculation is a compliance question, not a spreadsheet preference: model the entitlement honestly from day one, or face repricing the liability at the anniversary. For employees, the choice is equally direct: take the leave and protect your rest, or — once the new Act allows it — convert a quarter of the balance into money now, and keep the rest for the break you’re owed.
