Transport and access
Consider safety, reliability, journey time, resilience, access to opportunity and whole-of-network effects across transport modes.
Policy area · infrastructure
Build what lasts.
Deliver what matters.
Assess how governments have planned, funded, built and maintained New Zealand's infrastructure over roughly 2006–2026, and whether investments delivered their stated public benefits over the full asset life.
Assessment status: Insufficient evidence. This is an assessment framework. No project or government outcome is rated without project-level records and independent evidence.
What this page will assess
Water and essential networks
Track drinking water, wastewater and stormwater service quality, asset condition, resilience and affordability, accounting for governance changes.
Energy and digital connectivity
Examine security, capacity, reliability, access and readiness for future demand, using measures relevant to households and businesses.
Public assets and delivery
Compare planned and actual costs, timing, scope, maintenance needs, asset condition and benefits against the approved business case.
Actions and outcomes to document
Connect national plans and funding decisions to individual investments and the benefits they were intended to produce.
- Need, options and prioritisationDocument the problem, demand forecasts, alternatives considered, public consultation and rationale for the preferred option.
- Funding and procurementRecord approvals, funding sources, contingencies, contract structure and changes to budgets or responsibilities.
- Delivery and whole-of-life costCompare promised and actual scope, schedule, cost and maintenance obligations. Show re-baselines rather than hiding the original plan.
- Benefits, users and resilienceAssess post-completion outcomes against the business case, identify who benefited, and note independent evaluations and unresolved impacts.
Evidence to consult
Project pages should cite project-specific approvals, business cases, delivery reports, audits and post-implementation reviews wherever available.
Compare project estimates on consistent bases, disclose inflation adjustments and scope changes, and assess sunk costs separately from future costs and benefits.
