Holidays Act Compliance
Native support for NZ leave legislation – not a configuration headache
How does Affinity handle multi-site NZ payroll and leave calculations at scale?
NZ organisations with multiple sites or trans-Tasman structures face complexity well beyond a single Holidays Act calculation. Variable-hours employees, casual and part-time mixes, and site-specific collective agreements all compound at volume – and they compound differently for every employee.
Multi-site operations
Centralise payroll across every NZ location while still applying site-specific collective agreements, allowances and rosters – with consolidated reporting up to head office instead of a spreadsheet per site.
Leave calculation at scale
Average weekly earnings, average daily pay and 52-week leave averaging calculated correctly for every employee, every pay run – including variable-hours, casual and part-time staff, where the correct calculation changes person to person.
Trans-Tasman structures
Running entities on both sides of the Tasman? Payroll data, reporting and support sit on one platform rather than being reconciled between two separate systems. See our Australian payroll solutions.
Why this matters
The Cost of Getting It Wrong
- Holidays Act remediation averaging $500k+ for affected businesses
- Hours lost to manual checking and payroll rework every cycle
- Key person risk when payroll knowledge lives in one person's head
- Employee trust eroded by late or incorrect pay
With Affinity
- Holidays Act compliance built into every calculation
- Cut checking effort by approximately 50%
- Documentation and processes that don't depend on one person
- Accurate, on-time pay that builds rather than breaks trust

Does your industry make New Zealand payroll harder?
Holidays Act and collective agreements look different depending on your sector. See the rules that make your industry's payroll hard in the first place.
Who Affinity is – and isn't – for
Best for
New Zealand organisations with 100+ employees managing Holidays Act compliance, collective agreements, multi-site rosters or trans-Tasman operations, who want leave calculations and Payday Filing built into the platform rather than manual workarounds.
Less ideal
Very small NZ businesses with a handful of employees on simple, single-site pay. A lighter-weight, generic payroll tool will likely serve you better and more cheaply than a platform built for multi-site and Holidays Act complexity at scale.
Frequently asked questions
Is Affinity Payroll suitable for growing NZ businesses with complex payroll needs?
Absolutely. Whether you have 100 employees or 5,000+, Affinity is designed for New Zealand payroll complexity. We handle Holidays Act compliance, KiwiSaver, Payday Filing, and collective agreements out of the box. Our platform scales with you – many customers start with us as mid-sized businesses and grow into multi-site operations without switching providers.
Can your payroll solution support multi-location or ANZ-based organisations?
Yes. Affinity is built from the ground up for Australia and New Zealand. We support organisations operating across both countries from a single platform, with jurisdiction-specific compliance built in – not bolted on. Whether you have one NZ site or twenty across ANZ, you get consistent processes and unified reporting.
How does Affinity Payroll integrate with existing HR and workforce systems?
We offer flexible integration options including APIs, file-based connectors, and partnerships with leading HR and time systems. We integrate with HRIS platforms, time and attendance systems, and finance/ERP systems. During implementation, we work with you to design the integration approach that fits your technology landscape.
What level of support do clients receive during and after implementation?
Every Affinity customer gets a dedicated implementation lead and ongoing support from people who know your business. We don't use offshore call centres or ticketing queues. Our support team is based in New Zealand and Australia, understands local legislation, and can help with everything from configuration questions to strategic payroll advice.
How secure is employee and payroll data on your platform?
Security is foundational, not optional. Affinity is ISO 27001 certified, uses bank-grade encryption, and stores data in ANZ data centres. We align with IRD requirements and conduct regular security audits. Your employee data is protected with the same rigour financial institutions apply to banking data.
Starting a payroll review?
Two free guides for the two decisions that come before a vendor conversation – whether the change is worth making, and how to judge who can make it.
Build a payroll business case that gets approved
Cost the status quo, value the change, and get to the payback, ROI and NPV a board actually decides on. Includes a savings estimator and a board-ready template.
Choosing a payroll provider
Define what you actually need before you compare a single vendor – then turn it into a scored brief every vendor answers. Includes an RFP template and weighted scoring tool.
