Sanitarium Case Study: Dayforce Payroll & Compliance in NZ

Sanitarium Case Study: Dayforce Payroll & Compliance in NZ

Sanitarium

How can an organisation simplify payroll while staying compliant with New Zealand’s unique and potentially evolving regulatory environment?

Sanitarium answered this challenge by partnering with Alxemy to streamline processes and modernise workforce management. The result was a unified system that improved efficiency, scalability, and the employee experience.

The Problem

Sanitarium’s payroll and workforce management processes were spread across multiple legacy systems, creating risk and inefficiency. Key challenges included:

  • Compliance risk – Managing complex New Zealand payroll compliance under the Holidays Act was manual and error-prone.
  • Operational inefficiency – Payroll and rostering operated in silos, requiring time-consuming reconciliations.
  • Employee experience – Limited self-service payroll functionality reduced staff engagement.
  • Scalability concerns – The old systems lacked flexibility to support growth and evolving needs.

Sanitarium needed a smarter, unified payroll system that could handle NZ compliance without the manual headaches. Alxemy worked closely with the Australian partner but tailored every step to meet NZ’s unique rules.

The solution

Sanitarium had already partnered with an Australian Dayforce provider. Recognising the complexity of New Zealand payroll compliance, the partner recommended bringing Alxemy on board as a local specialist.

Alxemy focused on tailoring the Dayforce implementation to meet NZ’s unique requirements:

Payroll implementation

Configured Dayforce to support diverse employment types and ensure full alignment with the Holidays Act.

Time & Attendance

Integrated rostering and shift management directly into payroll, removing manual reconciliations.

Contract interpretation

Automated pay rules and entitlements across collective agreements and a newly acquired entity.

Alxemy’s phased approach included discovery workshops, detailed configuration, rigorous UAT, and multiple parallel payroll runs to validate accuracy.

Implementation Highlights

Successful implementation required more than just technology. It relied on collaboration, testing, and local expertise to ensure the system worked seamlessly for New Zealand’s unique requirements. Here’s what made the difference in bringing the solution to life:

  • Cross-border collaboration – Alxemy worked seamlessly with the Australian partner.
  • Close engagement – Joint workshops built confidence across HR, payroll, and operations.
  • Rigorous testing – Extensive UAT and parallel runs ensured accuracy.
  • Local expertise – In-depth knowledge of NZ legislation underpinned compliance.
  • Change management – Tailored training helped employees transition smoothly.

The Results

The impact was immediate across compliance, efficiency, and staff experience:

  • Compliance confidence – Automated calculations aligned with NZ payroll rules.
  • Efficiency gains – Streamlined processes reduced manual intervention and payroll errors.
  • Improved employee experience – Staff gained mobile self-service access to payslips, rostering, and leave.
  • Unified platform – HR, payroll, and workforce data consolidated into one system.
  • Future-ready – A scalable platform for analytics and workforce optimisation.

Client Feedback

Strong outcomes matter, but the real measure of success is how the client feels about the journey. Here’s how Sanitarium described the partnership:

“Partnering with Alxemy on our Dayforce implementation has been transformative for Sanitarium. Their deep understanding of New Zealand payroll and compliance meant we could trust the solution was configured correctly from the start. The team provided outstanding support, from testing through to go-live, and ensured our staff were confident with the system. We now have a single source of truth for HR, payroll and workforce management, improved efficiency, and with a much better experience for our people. We find the Alxemy team very easy to deal with and solution-focused, and we are going to continue working with them post-implementation to optimise the Dayforce solution for our business.”

Peter Hartnett, Head of People & Culture

Why It Matters for NZ Businesses

Breaking news: The Holidays Act to be replaced by the Employment Leave Act

Breaking news: The Holidays Act to be replaced by the Employment Leave Act

Employment Leave Act

On 23 September 2025, the Minister for Workplace Relations, Brooke van Velden, announced that the Cabinet had agreed to repeal the Holidays Act 2003 and replace it with a brand-new framework: the Employment Leave Act.

This is a significant development for New Zealand employers and employees alike. The Holidays Act has long been criticised as overly complex and difficult to administer, with payroll errors frequently arising from its inconsistent calculations. The Employment Leave Act aims to simplify entitlements and create a more transparent, hours-based system.

While the announcement signals a clear intention to reform, the new law still has a long journey before it takes effect. Here’s what we know so far, what’s changing, and what businesses should do to prepare.

Employment Leave Act in 5 Points

    1. Hours-based leave from day one, plus flexible cash-ups.
    2. Bill not introduced yet – likely mid-late 2026 with 2-year transition.
    3. Should cut payroll errors, but systems and contracts need updates.
    4. Likely to pass, but details may shift in Parliament.
    5. Keep following the Holidays Act and start preparing now.

What Was Announced

The Cabinet has confirmed several key pillars of the proposed Employment Leave Act (The Beehive):

  • Annual leave will accrue in hours from day one, at 0.0769 of each contracted hour worked (4/52).
  • Leave will be “banked” in hours, with no adjustments if contracted hours later change.
  • Employees will be able to cash up 25% of their total annual leave balance each year.
  • Sick leave will also accrue in hours from day one at 0.0385 of each contracted hour (2/52).
  • Bereavement leave and family violence leave will remain measured in days but available from day one.
  • A new Otherwise Working Day (OWD) test will help determine whether a public holiday falls on an employee’s expected working day.
  • Alternative holidays will accrue in hours, on a one-for-one basis, with each public holiday hour worked.
  • All leave will be paid at an hourly leave pay rate, based on base wages.
  • Fixed allowances will be paid in full during leave. 
  • Annual leave taken after parental leave will be paid as normal, removing the need for a 52-week averaging test.
  • Casual workers and employees working additional hours will be entitled to a 12.5% leave compensation payment on top of wages, rather than accruing additional leave.

The Minister has confirmed the goal to pass the Act within this parliamentary term remains on track, with a 24-month implementation period after passage (The Beehive).

 

This is a Government bill backed by Cabinet, making passage highly likely – but details may still shift during the Select Committee stage.

Where Things Stand

We are currently at the post-Cabinet policy decision stage. The Bill has not yet been introduced to Parliament. MBIE’s update confirms Cabinet’s decisions and notes the Bill will now be drafted and then introduced, triggering the official Select Committee process (MBIE).

  1. First reading
  2. Select Committee review (typically six months, with opportunities for public submissions)
  3. Second reading
  4. Committee of the Whole House
  5. Third reading
  6. Royal assent

If introduced in the coming months and given a normal Select Committee timeframe, mid–late 2026 is the earliest realistic passage date (The Beehive, MBIE). The Act would then have a 24-month implementation window, meaning practical go-live for most sectors in 2028.

The schooling sector will have up to 10 years to transition, given the complexity of its centralised payroll system (The Beehive).

Employers must keep applying the current Holidays Act until the new Employment Leave Act is fully passed and implemented.

Why This Matters

Replacing the Holidays Act isn’t just a technical change,  it will reshape how businesses manage leave and how employees access their entitlements.

Employers and payroll providers have long struggled with the Holidays Act, particularly with variable-hour and casual workers. These complexities have led to widespread remediation programmes, with many businesses still correcting errors today.

The proposed hours-based system aims to:

  • Make entitlements easier to calculate and administer
  • Reduce payroll disputes
  • Ensure greater fairness for employees
  • Simplify compliance for employers

Some of the main risks for employers include:

  • The need to adapt payroll systems to handle new accrual rules
  • Possible increase in liabilities and costs
  • Updating employment agreements
  • Re-training payroll and HR teams

The Government has signaled a 24-month implementation period to give organisations time to adapt (The Beehive).

Moving to an hours-based system could finally deliver the clarity and consistency employers and employees have been waiting for.

Will the Employment Leave Act really happen?

It’s natural to be sceptical. Past reviews, including one in 2023–2024, failed to deliver change. But this time momentum looks stronger:

  • The Bill is Government-backed and supported by the coalition (The Beehive).
  • The governing parties hold a working majority in Parliament, making passage highly likely.
  • The Act’s simplification focus makes it easier to defend politically.

That said, risks remain:

  • Select Committee scrutiny could alter details.
  • Timing is tight – failure to pass before the next election could stall progress.
  • Future Governments may amend or reprioritise.

Initial reporting suggests debate will centre on issues like hours-based sick leave and the 12.5% compensation payment (NZ Herald). But overall, the core direction is Government-led and positioned as simplification.

 

What Business Should Do Now

The Holidays Act 2003 remains in force. Nothing has legally changed yet, and no new rules apply until the proposed Employment Leave Act is introduced, debated, passed, and then given effect after a transition period. That process will take time, and final details may still shift.

However, employers should stay proactive so they’re not caught off guard. The following steps can help organisations prepare in the coming months:

1. Monitor official updates

  • Keep an eye on the Legislation website for the introduction of the Employment Leave Bill.
  • The Bill’s introduction will trigger the official Select Committee process with public submissions.
  • MBIE will also publish guidance and timelines. In the meantime, review the Cabinet paper and explanatory material, which outline proposed hourly accrual rates and transition plans.

2. Assess payroll system capability

  • Most payroll software will need updates to handle hourly leave accrual and the proposed 12.5% Leave Compensation Payment.
  • Ask your provider what development plans they have and when updates may be available.
  • Consider whether a future system change or upgrade might be required if your current platform is already under strain.

3. Analyse your workforce profile

  • Identify the number of staff on casual, variable, or part-time arrangements.
  • This will help you model potential impacts of the proposed compensation payment and accrual method.
  • Use this data to anticipate payroll cost shifts and budget accordingly.

4. Begin employee engagement planning

  • Even though no changes are in force, early communication builds trust.
  • Plan how you’ll explain the reforms once details are clearer.
  • Reassure staff that entitlements are secure under the current law, and that the business is preparing for a smooth transition when new rules apply.

5. Line up expert support

  • If you are an NZPPA member, we recommend attending the briefing on the 8th of October 2025 
  • The transition will be complex and may involve contract reviews, policy updates, payroll system reconfiguration, and balance conversions.
  • Begin conversations with payroll and HR specialists, legal advisors, or industry groups now so you have trusted guidance ready when the law is enacted.

Bottom line: Stay the course under the current Holidays Act, but start preparing quietly in the background. This ensures that when the Employment Leave Act does come into effect—most likely several years away—you’ll be ready to implement with minimal disruption.

 

Preparation today is about awareness, not action. By staying informed and planning carefully, organisations will be ready if and when the Employment Leave Act becomes law.

Frequently Asked Questions

1. When will the Employment Leave Act take effect?
The Bill hasn’t been introduced yet. If passed this term, the earliest practical start for most sectors is 2028 after a 24-month implementation window.

2. What happens to the Holidays Act in the meantime?
The Holidays Act 2003 remains in force until the new law is fully passed and implemented.

3. How will annual leave be calculated under the new Act?
Annual leave will accrue in hours from day one at 0.0769 per contracted hour (4/52). Leave is banked in hours.

4. Can employees cash up their leave?
Yes. Employees will be able to cash up 25% of their total annual leave balance each year.

5. How does the new law affect casual workers and additional hours?
Casual workers and employees working additional hours will receive a 12.5% leave compensation payment on top of wages, rather than accruing additional leave.

6. How will sick leave accrue?
Sick leave will accrue in hours from day one at 0.0385 per contracted hour (2/52).

7. How are public holidays handled?
A new Otherwise Working Day test will determine if a public holiday falls on an expected working day. Alternative holidays will accrue hour-for-hour with each public holiday hour worked.

8. How will leave be paid?
All leave will be paid at an hourly leave pay rate based on base wages; fixed allowances will be paid per normal while employees are on leave.

9. What should employers do now?
Employers must continue to follow the Holidays Act 2003 as nothing has changed yet. It’s sensible to stay informed by monitoring the Bill’s progress and upcoming Select Committee process, but avoid making changes until the law is confirmed. In the meantime, you can start quietly assessing payroll system readiness for hourly accrual, reviewing how your workforce profile might be affected, and planning future communication and training so you’re prepared if and when the Employment Leave Act becomes law.

The Bottom Line

The replacement of the Holidays Act with the Employment Leave Act is one of the most significant workplace law reforms in recent memory. If passed, it promises to simplify payroll compliance, ensure entitlements are clearer and fairer, and reduce the errors that have plagued employers for decades.

But the change won’t happen overnight. With the Bill yet to be introduced, an implementation period of two years, and carve-outs for specific sectors, we’re looking at a 2028 start date for most businesses.

Until then, the Holidays Act 2003 remains the law of the land. Employers should continue to comply with its requirements, while keeping a close eye on developments in Parliament.

Preparation today will pay dividends tomorrow. By understanding the proposed reforms and planning early, organisations can ensure they’re ready for the Employment Leave Act – whenever it arrives.

Key Takeaways:

  • The Employment Leave Act replaces the Holidays Act with an hours-based accrual system.
  • Passage is likely, but implementation won’t happen until 2028 for most sectors.
  • Employers will need to update payroll systems, agreements, and processes.
  • The 24-month transition period offers time to adapt, but planning is essential.
  • Staying informed and seeking advice now will help organisations avoid compliance risks later.
Enterprise HCM Software Implementation – Part 5: Training and Testing

Enterprise HCM Software Implementation – Part 5: Training and Testing

enterprise HCM software implementation training and testing

Implementing a new enterprise Human Capital Management (HCM) system isn’t just about configuration. It is about people using it confidently and the system performing under real-world conditions.

As your project moves from build to business-facing phases, training and testing become the proving ground of your investment.

This is where capability is built, risks are exposed early, and confidence is created, paving the way for a smooth go-live.

This part of our multi-part implementation guide explains how to structure training and testing to de-risk your HCM project, meet New Zealand compliance requirements, and prepare your workforce for success.

At a glance…

    1. Start training and testing early as core workstreams.
    2. Phase training: admins, champions, managers, then end users.
    3. Test everyday, complex, and edge-case scenarios thoroughly too.
    4.  Run UAT with current, Holidays Act compliant data.

5. Track progress with gates, user stories, and dashboards.

Why Training and Testing Are Critical

Training and testing aren’t “end of project” tasks. They are core delivery workstreams that start well before go-live. 

They ensure that:

  • Administrators understand the system deeply enough to support it
  • Managers and champions can validate real business processes
  • End users can adopt the system quickly with minimal disruption
  • Payroll-critical functionality complies with NZ legislation (e.g. Holidays Act)

Business stakeholders can confidently sign off readiness. This builds directly on the foundation explained in the previous article, Provisioning, build and vendor testing (part 4), where your system is stabilised and handed to the business for the first time. Without that preparation, effective training and testing cannot happen.

 

Training builds capability. Testing builds confidence. Together, they are the real measure of readiness for go-live.

Training: Building Capability in Stages

Training should be delivered in phases, not crammed into a one-off workshop. Each phase builds capability at the right time, for the right people.

Administrator Training (Pre-Scenario Testing)

Train administrators (typically Payroll and HR specialists) first so they can lead testing. Go beyond navigation. Cover:

  • Rules engine configuration
  • Workflow design and escalation
  • Reporting and data extracts
  • Handling complex NZ requirements (like Holidays Act compliance)

Well-trained admins become your first line of support and your first testers, validating business-critical logic before involving wider audiences.

Champion & Manager Training (Pre-UAT)

Once the system passes initial scenario testing, train business unit champions, people managers, and operational leads. They’ll help design and execute UAT, so they must understand:

  • Day-to-day business processes.
  • Data entry, approvals, and reporting flows.
  • Known pain points in the legacy system.

Early involvement builds ownership and advocacy, reducing resistance during rollout.

End-User Training (Closer to Go-Live)

End-user training happens last, just before parallel runs and go-live, so it reflects the final configuration. 

It should cover:

  • Accessing portals, kiosks, or mobile apps.
  • Submitting timesheets and leave.
  • Viewing payslips and personal information.

Where possible, have champions or managers deliver this training. Familiar faces improve trust and adoption.

Train early, train the right people, and keep it practical. That is how capability sticks.

Scenario Testing: Proving the System Under Pressure

Scenario testing validates that the system works as designed across every business situation, from the routine to the highly unusual.

It is led by the client project team with vendor support, and should be treated as a full-scale operational rehearsal.

Scope of Testing: 

  • Everyday processes – standard pay runs, leave requests, timesheets, onboarding and terminations.
  • Complex allowances and deductions – overtime, shift allowances, industry-specific pay rules.
  • Edge cases – For example, when Christmas and Boxing Day fall on a weekend and are Mondayised and Tuesdayised under NZ law.
  • Volume and breadth – hundreds of cases across contracts, patterns, and employee types.

Scenario testing is where confidence is built, but only if it’s structured, documented, and exhaustive. Many organisations undercook this phase. Our article When scenario testing takes a backseat shows what happens when testing is rushed or deprioritised: confidence collapses, defects surface late, and go-live becomes a gamble. Treat scenario testing as a rehearsal, not an afterthought.

 

If it is not tested, it is not ready. Treat scenario testing like a full rehearsal.

User Acceptance Testing (UAT) – Business Validation

UAT is where the business signs off that the system is ready for live use.
Unlike scenario testing (which is theoretical), UAT validates real-world business operations.

Typical UAT Activities:

  • Selected stores or branches clock staff in both legacy and new systems.
  • Managers submit leave approvals in the new system..
  • Payroll teams process their regular tasks through the platform.

The goal is not only accuracy, it’s verifying that the system supports how the business actually operates.

Building a Structured Testing Framework

To avoid chaos, testing must be methodical and measurable. Best practices include:

Entry and Exit Gates

Define clear prerequisites to start a phase (e.g. data loaded, system stable) and conditions to close it (e.g. no payroll-critical defects open).

Test Cases as User Stories

Write test cases in plain business language and include expected results to avoid subjectivity:

“As a store manager, I want to approve annual leave so the roster updates correctly.”

 

Issues Register and Retesting

  • Log all defects with severity, category, and owner.
  • Retest and close every issue.
  • Maintain audit trails for compliance and risk reviews.

Progress Tracking

  • Maintain test execution dashboards.
  • Show what’s complete, what’s blocked, and where issues cluster.
  • Keep stakeholders informed at all times.

Accurate data is not just a nice-to-have for UAT.

Data Refresh – Creating a Realistic UAT Environment

Before UAT begins, refresh data to reflect current real-world conditions so results are accurate and compliant.

Key Elements to Refresh

  • Current leave balances and entitlements.
  • 52-week earnings history (critical for Holidays Act calculations).
  • Employee master data (contracts, job classifications, personal details).

Before UAT begins, refresh data to reflect current real-world conditions so results are accurate and compliant. This step links back to Project initiation, scope and design (part 3), where decisions about data migration, employee records, and Holidays Act rules first take shape. Good design at the start makes UAT data refresh far smoother later on.

Best Practices for Training and Testing

  • Communicate constantly: keep vendors, admins, and managers aligned.
  • Engage stakeholders early: prevent resistance and rework.
  • Document everything: training plans, test cases, sign-offs, defect logs.
  • Build feedback loops: refine based on results, not assumptions.
  • Prioritise risk areas: payroll-critical processes should be tested first.

This ensures training and testing deliver capability, confidence, and control.

Preparing for Go-Live

Once UAT is complete and all payroll-critical defects are resolved, attention shifts to preparing for parallel runs and final cutover – the bridge between testing and live operation.

This phase is about readiness, not speed. It ensures your system, processes, and people perform as expected under real-world conditions before go-live. Parallel runs, the focus of our next article, simulate live payrolls and operations, validating that everything functions accurately at scale.

Key preparation activities include:

  • Reconfirm success criteria and sign-offs
  • Finalise user access and security settings
  • Schedule hypercare support for the first pay cycles

This preparation lays the foundation for a confident transition into the final stage about parallel runs and go-live.

Conclusion

Training and testing are not peripheral activities – they are the proving ground of any payroll or HCM project.
Staged training builds capability at the right time, while scenario testing and UAT validate that the system performs under real-world pressure.

By applying structured testing methods, rigorous documentation, and accurate data, organisations create the confidence needed to move into Part 6: parallel runs and go-live – which we explore next in the concluding part of this series.

Frequently Asked Questions

What is scenario testing in HCM projects?

Scenario testing validates how the system handles everyday, complex, and edge-case scenarios to ensure it operates reliably in the real world.

How is UAT different from scenario testing?

UAT is run by business users using real data and real processes, while scenario testing is controlled scripts run by the project team.

When should end-user training occur?

Just before go-live, once the system is stable and configuration is finalised.

Why is data refresh important before UAT?

It ensures testing uses current balances, entitlements, and histories, critical for NZ Holidays Act compliance.

Who signs off UAT completion?

Representatives from HR, Payroll, Operations, and Finance should formally approve UAT completion before go-live.
