Services

Matatihi delivers decision-ready social impact assessments for Māori organisations and purpose-led teams, with SROI available when monetisation adds clarity. We also provide economic impact analysis (economic footprint and multipliers) as a separate, complementary output. When the work does not fit a standard scope, we support project-based research and decision science across social, economic, and environmental questions, grounded in kaupapa Māori contexts where relevant.

SOCIAL

Social impact and SROI evaluations

Independent evaluations with audit-ready outputs and CBAx-compatible reporting for funders, boards, and agencies.

  • Fixed prices with clear scope, timelines, and conservative assumptions
  • Board-ready summary outputs plus validation / provenance checks
  • CBAx bridging for straightforward agency review
  • Option to report economic footprint (multipliers) alongside — not inside the ratio
  • Kaupapa Māori expertise: impact frameworks that reflect whānau, mana and kaitiakitanga outcomes, with reporting that still meets funder and agency scrutiny

Designed for scrutiny: clear counterfactuals, attribution, and defensible valuation choices.

ECONOMIC

Economic impact analysis (GDP, jobs, wages)

Fast, lightweight estimates of GDP (value added), employment, wages, and NZ-content — built for Aotearoa funding, investment, and reporting.

  • Start with the free calculator for indicative scoping
  • Rapid analyst-reviewed “impact note” when numbers must be defensible
  • Decision-ready reports with scenarios and clear “what’s in / what’s out” boundaries
  • Transparent assumptions, sensitivities, and conservative framing

Built for decisions, not just reporting.

RESEARCH SUPPORT

Research, evaluation, and decision science support

Some projects don’t fit a standard service line — they need an economist or decision scientist to plug into an existing team. We support organisations and researchers with methods, modelling, evidence synthesis, and decision-ready reporting.

  • Economic and non-market valuation (social, cultural, environmental outcomes)
  • Evaluation design and QA: causal logic, assumptions discipline, sensitivity structure
  • Decision science: trade-offs, priorities, and preference elicitation (MCDA-style problems)
  • Evidence synthesis and parameter packs that stand up to scrutiny

Good fit when you need…

  • Independent methods support before funding bids, investment memos, or publication
  • Numbers that must survive challenge from boards, agencies, or technical reviewers
  • A clear narrative that matches the maths (and avoids over-claiming)
  • Kaupapa Māori-aligned evaluation: outcomes, indicators, and interpretation that reflect mana, mauri, whanaungatanga and kaitiakitanga, not just Western proxy metrics.
  • Iwi/Māori governance fit: decision support and reporting designed for rūnanga, trusts, incorporations and funders, with clear boundaries, transparent assumptions, and defensible evidence standards.

Typical partners include researchers, CRIs, councils, iwi organisations, foundations, and mission-led programmes.
