| Building Act | General regulatory framework to ensure building safety, quality, and accessibility | Enhanced standards on energy efficiency and fire safety |
| Resource Management Act (RMA) | Sustainable land resource management and environmental control | Increased integration of ecological requirements in permit approvals |
| Healthy Homes Standards | Improvement of thermal comfort, insulation, ventilation, and moisture management for rental housing | Full compliance required by July 1, 2024 |
Historical evolution shows a progressive increase in requirements: initially focused on structural or sanitary building safety (Building Act), standards incorporated a strong environmental dimension starting in the early 2000s with the RMA. The “Healthy Homes Standards” system, gradually implemented since 2019 and fully enforced in 2024, illustrates this shift toward healthier housing: enhanced insulation, mandatory ventilation in damp rooms, and effective moisture control systems.
Main Objectives
- Reduce energy consumption
- Promote the use of sustainable materials
- Limit negative impacts on local biodiversity
- Provide a healthy environment for occupants
These objectives align with New Zealand’s national policies aiming for carbon neutrality by 2050, as well as the government strategy to improve public health through better-performing housing.
Expected Benefits
Environmental
- Significant reduction in CO₂ emissions related to heating/cooling
- Enhanced preservation of natural heritage (sustainable land/water management)
Economic
- Higher property valuation for assets meeting new requirements
- Long-term reduction in energy bills
Social
- Clear improvement in resident well-being/quality of life (less damp/cold housing)
- Reduction in respiratory illnesses associated with substandard housing
Concrete Examples
The City Rail Link program in Auckland not only incorporates low-carbon urban mobility but also includes numerous new buildings certified as “green” according to local standards. Many recent residential neighborhoods around Auckland-Wellington already benefit from modern infrastructure meeting these new requirements – high-performance thermal insulation and innovative collective systems for water/energy management.
New Measures Planned or Expected Revisions for 2025
The government plans further strengthening of minimum energy efficiency requirements during major renovations and possible expansion of the “Green Star NZ” label to existing buildings. A national consultation is also announced to integrate more requirements related to climate resilience in response to increasing extreme weather events.
Key Takeaway: New Zealand’s green real estate now relies on a robust legislative framework that continues to evolve dynamically, ensuring that every real estate project concretely contributes to building a low-carbon and resilient society.
Good to Know:
Green building standards in New Zealand play a crucial role in sustainable development, influencing how buildings are designed, constructed, and managed to minimize their environmental impact.
