Here's how we see it.
What genuinely gets simpler.
Credit where it's due. The Bill delivers real simplifications:
- Annual Leave moves from weeks to hours as the unit of measure, removing one of the most contested and error-prone calculations in the current Act.
- No separate rate for Annual Leave earned during parental leave — returning parents will be paid at the same rate as any other Annual Leave, which is a long-overdue fix.
- One consolidated leave pay rate across leave types, replacing the multi-method comparisons (RDP, ADP, AWE, OWP) that have driven so much of the historic non-compliance.
These are genuine wins. If your workforce is straightforward - permanent, salaried, predictable hours - much of the compliance overhead will drop away.
Where new complexity is introduced.
For complex workforces - health, local government, education, 24/7 rostered environments - a different picture emerges.
Not every leave type moves to hours.
Some entitlements will still be managed in days, which means payroll systems must simultaneously operate two units of measure and reconcile between them.
New rules on which hours accrue and which don't.
The Bill draws a hard line between standard hours, additional hours and casual hours. Only standard hours accrue Annual and Sick Leave. Additional and casual hours attract a 12.5% Leave Compensation Payment (LCP) instead of accrual. That's a clean concept — but the execution requires payroll to correctly categorise every hour, every pay period, for every employee.
Accrual moves with the employee.
Because accrual is tied to standard hours as they stand at the time worked, any change to an employee's contracted pattern flows straight through into their entitlement. Keeping accrual correct, LCP correct, and — critically — ensuring no employee is paid both an accrual and an LCP for the same hour, is a non-trivial engineering problem. It might sound simple. Accurately applying it, at scale, across a complex workforce, will not be.
The guidance gap.
Some areas of the Bill will need further clarification through Select Committee and subsequent MBIE guidance. Without that clarity, well-intentioned employers’ risk conceptual non-compliance — being technically wrong even while trying hard to be right.
The elephant in the room: contracted leave
Here's the piece the headlines are missing. Legislated leave is only part of most employment relationships. Many NZ employers have contracted entitlements - shift leave, long service leave, retirement leave, purchased leave - defined in days or weeks. And a great many of those agreements state that this leave is paid "as per Annual Leave rules". When those Annual Leave rules change, the contracted rules don't automatically follow. Legislating a change that produces a lower entitlement is one thing. Negotiating a lower contracted entitlement with employees and unions is an entirely different proposition. Employees and their representatives may not going to accept reduced contracted payments simply because a completely different leave type has been reformed.
One country, one flip day.
And then there's the industry-wide challenge. Every employer in New Zealand will transition from Holidays Act compliance to ELB compliance on the same day - currently proposed as two years after the Bill receives Royal Assent.
On the face of it, that looks insurmountable for the ecosystem - employers, payroll providers, professional services, and outsourcing partners all pivoting simultaneously. The only realistic answer is automation. Manual conversion, employee-by-employee, agreement-by-agreement, will not scale. It has to be engineered.
Where AMS is heading?
We're already gearing up. Our position is straightforward:
- The reform is welcome, but the "simplification" narrative underestimates the delivery challenge for real-world workforces.
- Preparation must start now — not after the Bill passes, and definitely not after implementation guidance lands.
- The transition itself must be an automated, engineered process - for our customers and for the industry.
If you'd like to talk about what ELB readiness looks like for your organisation, from configuration and conversion through to the contracted-leave conversation with your workforce, we'd love to have a chat.
