Summary

Aurion and Definitiv are both Australian-focused payroll platforms, but with different heritage and reach. Aurion is a long-established AU payroll and HR platform with a broad HR suite and government-grade certifications. Definitiv is a cloud-native AU payroll and workforce-management platform, now part of The Access Group, focused on complex awards and integrated rostering. Alongside them, this page shows how Affinity, a dedicated AU/NZ payroll platform, compares for organisations whose complexity is concentrated in Australia and New Zealand.

How Aurion and Definitiv differ

Aurion has 35-plus years of Australian payroll heritage. Owned by RGF Staffing ANZ (part of Recruit Holdings, Japan), it pairs an established AU award interpretation engine with a broader HR suite (recruitment, performance, learning, WHS) and government-grade certifications including IRAP and ASAE 3402 Type 2. Its NZ coverage is limited to tax updates and banking interfaces, so its focus is squarely Australian.

Definitiv is a cloud-native AU specialist, originally built in Perth and now owned by The Access Group. It markets Definitiv Evo across Australia, New Zealand and Singapore, with a 100% configurable Award Engine and purpose-built rostering that flows live time-tracking into costed payroll.

The core distinction: Aurion offers Australian government-grade payroll with HR breadth; Definitiv offers a cloud-native award engine with integrated workforce management and slightly wider AU/NZ/Singapore reach. Both are AU-centric rather than multi-country.

Where Aurion fits

Aurion is built for Australian organisations – particularly in government and the public sector – that need government-grade certification (IRAP, ASAE 3402 Type 2) alongside a broad HR suite spanning recruitment, performance, learning, and WHS. Its 35-plus years of Australian payroll heritage and date-centric processing are genuine strengths for AU-centric employers.

Where Definitiv fits

Definitiv is built for mid-to-large Australian organisations with complex, multi-award structures that want a cloud-native platform combining a 100% configurable Award Engine with integrated rostering and costed payroll. Backed by The Access Group and with data hosted in Australia, it suits businesses wanting AU-focused depth that also extends to NZ and Singapore.

Where Affinity fits

Where Aurion leads on AU government certification and HR breadth, and Definitiv on a cloud-native award engine with WFM, Affinity optimises for AU/NZ depth across both countries. For organisations whose payroll complexity is concentrated in Australia and New Zealand – many modern awards, EBAs, Holidays Act calculations, STP Phase 2, Pay Day Super – a specialist engine with pre-payslip intelligence, delivery-model flexibility, local data residency, and named local support is a different proposition. The NZ Holidays Act in particular requires deep local engine work that AU-centric platforms may not cover to the same depth.

Frequently asked questions

Is Aurion or Definitiv better for Australian payroll?

Both handle Australian payroll well. Aurion brings 35-plus years of heritage, government-grade certifications, and a broad HR suite; Definitiv is a cloud-native platform with a 100% configurable Award Engine and integrated rostering. For complex modern awards or EBAs, test either against your specific scenarios – or evaluate an AU/NZ specialist such as Affinity, whose award interpretation engine is purpose-built for that complexity.

Do Aurion and Definitiv handle New Zealand payroll?

Aurion's NZ coverage is limited to tax updates and banking interfaces, so it is AU-focused. Definitiv supports NZ (and Singapore) payroll, with Holidays Act depth to confirm directly. NZ payroll – Holidays Act, KiwiSaver, Payday Filing with IRD – requires deep local engine work. Affinity runs a purpose-built NZ engine with an NZ-based support team on the same platform as its Australian payroll.
