Pay public holidays correctly without paying more than you need to

We help you define a fair "otherwise working day" policy and automate eligibility decisions so you pay time-and-a-half to those who work—and day-in-lieu only when it's truly owed.

The biggest headache isn't the rate (time-and-a-half)—it's deciding who actually earns a day-in-lieu. Many businesses give everyone who worked the day-in-lieu by default to avoid admin risk, which quietly doubles costs.

Why "otherwise working day" is so tricky

The law says an alternative holiday is owed only if the public holiday would otherwise have been a working day for the employee—but in flexible and rostered environments, this can be hard to prove and even harder to operationalise.

⚠️The Current Problem
Irregular rosters: Staff swap shifts, pick up extras, or rotate; last-minute changes create ambiguity
Manual guesswork: HR teams spend hours trying to determine patterns from spreadsheets
Over-pay risk: Many businesses give everyone day-in-lieu by default to avoid admin risk
Double costs: Pay the worker and cover the backfill when they take the day
What the Law Actually Says
Time-and-a-half: Always applies for hours worked on a public holiday
Alternative holiday: Only if the public holiday would otherwise have been a working day
Multi-factor test: Consider work patterns, employment agreement, reasonable expectations, past history
No cherry-picking: Must consider all relevant factors in good faith

Operational risk: Over-pay and you erode margins; under-pay and you risk arrears, penalties, and reputational harm.

MBIE guidance highlights the need to apply the full factors in good faith—but gives little practical guidance on how to do this at scale.

Our solution: Define, agree, and automate

We work with you to codify a fair, defensible "otherwise working day" policy that reflects your roster reality but still aligns with MBIE's multi-factor test.

Step 1
📋
Define a Fair Policy
Create defensible "otherwise working day" rules
Pattern rules based on roster expectations
Attendance heuristics (e.g., "4 of last 8 Mondays")

On-call and call-out scenarios
Step 2
✍️
Secure Agreement
Document it in employment agreements
Clear, crystal-clear policy language
Employee consultation and buy-in
Integration with existing agreements
Transparency reduces disputes

💰 Cost Recovery Example

A single avoided unnecessary alternative holiday can cover the service cost at typical hourly rates. Most clients see ROI within the first public holiday.

Example scenarios you can publish

See how the calculator handles real-world situations with clear, defensible decisions.

Gets Alternative Holiday
Fixed Monday-Friday worker on Waitangi Day
Regular schedule shows Monday as otherwise working day → Time-and-a-half for hours worked plus alternative holiday.
On-call with restrictions, not called out
Otherwise working day + restrictions meant they didn't enjoy a full holiday → Alternative holiday applies.
No Alternative Holiday
Casual worker picks up Easter Monday only
Rarely works Mondays per your policy → Time-and-a-half for hours worked, but no alternative holiday.
Employed only to work public holidays
No otherwise working day pattern → Time-and-a-half while working, but no alternative holiday.
🕐Complex Timing Scenarios
Shift crosses midnight into public holiday
Only the hours inside the public holiday get time-and-a-half; alternative holiday depends on whether that calendar day is otherwise a working day.
Variable roster with pattern
Worker has irregular schedule but meets your benchmark (e.g., "worked 5 of last 8 Mondays") → Gets alternative holiday.
