## What this document contributes

Sarah Hogan and Philippa Miller-Moore’s NZIER report for The Selwyn Foundation sets out five investment priorities for improving later life: better longevity data, suitable housing, life-course planning, integrated support for independence and social connection, and specialist care for frailty. It argues that treating everyone aged 65+ as one group obscures substantial differences and reinforces ageism. The July 2025 document synthesises existing research and offers recommendations rather than reporting an original cohort study or a tested programme. NZIER’s publisher page dates its release to 19 August 2025. The recommendations span government, community and service responses; publication does not establish adoption, funding, implementation or demonstrated clinical or fiscal effects.

## Substantive findings

- The document cover says July 2025; NZIER’s publisher page is dated 19 August 2025. These are report and release dates, respectively.
- Authors are Sarah Hogan and Philippa Miller-Moore; commissioned by The Selwyn Foundation, with quality assurance and Haemata peer-review advice acknowledged (physical p.2).
- Priority 1 calls for more granular longevity data and reporting to reflect diversity within older populations and challenge age-based assumptions (physical pp.6–7).
- Priority 2 emphasises suitable, affordable and accessible housing, including the position of older renters and housing security (physical pp.8–9).
- Priority 3 extends long-term life planning beyond retirement finances to health, housing, work, relationships and other life domains (physical pp.10–11).
- Priority 4 concerns integrated care, social connection and maintaining independence; priority 5 concerns specialist geriatric, frailty and rehabilitation services (physical pp.12–15).
- The report is a synthesis and investment argument using secondary evidence of varying dates; it does not measure the impact of implementing the five priorities or establish current government commitments.

## Evidence limits

Commissioned July 2025 evidence synthesis, released 19 August 2025. Investment recommendations and cited secondary health/cost evidence are not implemented policy, proven intervention effects or present-day medical guidance. Mixed reference years and older-population heterogeneity apply.

This companion is an evidence guide, not a replacement original, a new survey or a statement that historical proposals were implemented.
