Council Payroll Goes Live on New Platform
Business news is presented by
Invercargill City Council has successfully switched its payroll system to a cloud-based platform, processing its first live pay run for around 550 employees in early July 2026.
The new system, built on TechnologyOne's Human Resources and Payroll platform and implemented by Australian technology firm Atturra, replaces a patchwork of ageing, separate payroll and HR applications the council had relied on for years. It is part of the council's broader multi-year modernisation programme, which was set up after an extended period of minimal investment in core business technology.
Payroll is not a function you get to run badly even once. With a workforce spanning multiple employment arrangements and complex pay rules — all integrated with other business systems — getting it wrong would have hurt real people on real pay days. The fact that the first production run went through without incident is the actual story here.
The project kicked off in early 2024. To reduce risk, the council ran a smaller go-live at Invercargill Airport in February 2026 first, using that as a test environment before rolling the system out to the full council workforce. A sensible call — the kind of unglamorous, methodical groundwork that rarely makes headlines but matters enormously when 550 salaries are on the line.
The road was not entirely smooth. The council and Atturra encountered challenges around scope, system integrations and overall complexity, addressing them through tighter governance, additional testing and collaborative problem-solving. Payroll accuracy and business continuity were the non-negotiable conditions for go-live.
Council chief executive Michael Day said completing the first live payroll reflected the commitment of the payroll, people and culture, information services and project teams, alongside Atturra's support as implementation partner. "Successfully implementing a new payroll platform is a significant technology milestone because every employee depends on it operating accurately and reliably," Day said.
Atturra's New Zealand general manager for business applications, John Mazenier, said the project showed what councils could achieve through strong governance, detailed testing and close collaboration. He framed the lesson for others considering similar upgrades: treat payroll modernisation as an operational change programme, not a software deployment.
That distinction matters. Councils that approach technology upgrades as a procurement exercise rather than a change management one tend to find out the hard way why payroll week is not the moment for surprises.
Immediate benefits are modest — accurate pays, a supported platform, better connection between HR and payroll functions. Improved reporting and more streamlined processes are expected as the council embeds the system over time. Nothing flashy. Just fewer spreadsheets, and staff who get paid correctly. After years of running on outdated systems, that is enough.
