Our role is to transform how New Zealand invests in social outcomes, prioritising relationships, integrating evidence and delivery, fostering innovation, and building enduring systems for lasting positive change.
We work across government to help shift the social services system from responding to crisis to investing earlier, supporting what works, and improving long-term outcomes.
Our vision is that people and communities can reach their full potential.
SIA leads, builds and demonstrates a social investment approach that supports smarter spending, earlier support and better results across the social sector.
As a central agency, we help government direct resources where they will make the greatest difference – particularly for people and families with complex or persistent needs. We do this by bringing together data, social science and lived experience, and by strengthening the connection between evidence and delivery.
Through the Social Investment Fund, and through our system leadership role, we support new ways of commissioning and investing that are outcome-focused, evidence-informed and people-centred.
The Minister for Social Investment leads the social investment work programme with a group of Social Investment Ministers, supported by independent advice from the Social Investment Board.
As a Central Agency, SIA provides the following.
Our work is contributing to more outcome-focused agreements that give providers certainty to plan and innovate; earlier support that reduces reliance on high-cost crisis services; greater use of data by communities and iwi to design local solutions; better tools, insights and guidance to support smarter investment decisions; a more connected and collaborative system focused on shared outcomes; and a culture of learning and transparency.
Multi‑year, outcome‑focused agreements are giving organisations who provide social services the certainty to plan ahead and innovate. Reduced reporting burden means more time spent supporting families and whānau.
Instead of waiting for crisis and funding services based on habit or historical precedent, social investment uses data, social science and community knowledge to see what’s coming and act early – reducing cost and improving long-term outcomes.
Communities and iwi leaders now have access to clearer, more usable data about what’s happening in their rohe. This supports community‑led planning and lays the foundation for community-led commissioning.
Dashboards, data stories and guidance from SIA are helping NGOs and other government agencies understand which approaches work for whom, and why – supporting smarter services across the system.
Through guidance, standards and cross‑agency engagement, SIA is helping build a shared language and shared expectations for social investment – shifting the system from fragmented activity to coordinated, outcomes‑focused action.
By openly sharing insights – including what doesn’t work – we’re helping establish a system that learns, adapts and improves over time.
Our name, Toi Hau Tāngata, reflects what it means to live well – centred on the wellbeing of people across generations. Toi means peak or excellence, Hau refers to life force or vital essence, and Tāngata means people.
The name was gifted to us by Mohi Apou of Taranaki‑Whanganui descent and comes from Te Hau Tai Tāngata, a karakia passed down through oral tradition. It anchors our work in a Māori worldview that values people, relationships and collective wellbeing, and reflects our aspiration that people, whānau and communities can live the lives they value.
Our values guide our work.
