## What the story says

TMNZ, a New Zealand tax payment fintech, uses self-hosted n8n to automate tasks such as market research and HR processes, and to build agentic AI workflows like invoice processing and data enrichment. It also combines n8n with AI agents and MCP servers on its LLM stack.

Summary written by usedby from the source page, in English. The figures are those of n8n and TMNZ, not ours.

> It’s not all just about time savings either, a big proportion of the 400 hours savings gained each month (and growing) are through productivity improvements and enabling a cultural shift in the way that the organisation works.

- **150,000**: “running around 150,000 executions each month”
- **up to an hour**: “saving up to an hour per execution”
- **more than a third**: “Today more than a third of TMNZ staff are using n8n”

> n8n is helping to shift our culture from ‘this is too hard to solve - let’s just use a spreadsheet for now’ to ‘what can we do to systemise, automate and use AI to scale this’. Just understanding what’s going on in a workflow is really powerful for all stakeholders.
