What Are Green Certifications?
Green certifications are official recognitions awarded to buildings that meet specific environmental standards and sustainability practices. These certifications assess a property’s performance across several key areas, including:
- Energy efficiency
- Water conservation
- Indoor air quality
- Use of sustainable materials
- Waste reduction
Achieving a green certification demonstrates that a property goes beyond minimum compliance, actively contributing to a healthier environment and improved occupant wellbeing. These certifications are independently assessed, providing tangible evidence of your property’s eco-friendly credentials.
Types of Green Certifications Available in New Zealand
New Zealand offers a range of green certifications tailored to both residential and commercial properties. The most reputable and widely recognised include:
| Certification | Best For | Administered By | Focus Areas |
| Homestar | New and existing homes | NZ Green Building Council (NZGBC) | Energy, water, health, comfort, waste, materials |
| Green Star | Commercial & large-scale res. | NZGBC | Design, construction, operation, carbon, water |
| NABERSNZ | Offices (energy performance) | NZGBC | Energy use, benchmarking, operational efficiency |
| HomeFit | Existing homes (retrofit) | NZGBC | Warmth, dryness, safety, energy efficiency |
| LEED | All building types | USGBC (used globally, incl. NZ) | Comprehensive sustainability, global standard |
| Net Zero™ | Any building (carbon focus) | NZGBC | Net zero carbon emissions in operation |
- Homestar rates homes on a scale from 6 to 10, with higher scores reflecting better performance in energy, water, health, and comfort. Homestar is increasingly seen as the gold standard for eco-friendly homes in Wellington and across New Zealand.
- Green Star is internationally recognised and widely used for commercial buildings, including offices, schools, and apartment complexes. Ratings range from 4 stars (best practice) to 6 stars (world leadership).
- NABERSNZ benchmarks the energy performance of office spaces, allowing landlords to compare and improve their buildings’ efficiency.
- HomeFit is a practical certification for existing homes, focusing on warmth, dryness, and safety-key concerns for Wellington’s climate.
- LEED is a globally recognised certification, increasingly adopted in New Zealand for new and existing buildings seeking international appeal.
- Net Zero™ is the latest NZGBC certification, tracking all major sources of operational carbon emissions.
Steps to Obtain a Green Certification
While the specific process varies by certification, the general steps are similar:
- Choose the Right Certification
- Assess your property’s type, age, and sustainability goals to select the most appropriate certification (e.g., Homestar for homes, Green Star for commercial buildings).
- Engage with an Accredited Professional
- Work with a certified assessor or sustainability consultant. Many property management companies, including Taylor Property Plus, have established relationships with these professionals.
- Pre-Assessment and Benchmarking
- Conduct an initial assessment to identify strengths and areas for improvement (e.g., insulation, heating, water efficiency, materials).
- Implement Improvements
- Make necessary upgrades, such as installing energy-efficient appliances, improving insulation, or adding water-saving fixtures.
- Documentation and Application
- Compile evidence of improvements (receipts, plans, photos) and submit a formal application to the certifying body.
- Third-Party Assessment
- An independent assessor reviews your application and may conduct a site visit.
- Certification Awarded
- Upon successful review, your property receives its certification and can be marketed as a certified sustainable rental.
How Certifications Increase Property Value and Tenant Interest
1. Higher Rental Yields and Sale Prices
Recent research in New Zealand shows that green-certified properties command significant premiums. For example, Green Star-certified buildings enjoy a sales premium of 3.7% to 7.5%, while those with both Green Star and a high NABERSNZ rating can see up to a 9.8% premium on sale price and a 6.7% rental premium.
2. Lower Vacancy Rates
Certified properties consistently have higher occupancy rates, up to 98-99% for top-rated buildings, compared to non-certified equivalents. This means more consistent returns and less downtime for landlords.
3. Attracting Quality Tenants
Modern tenants, especially in Wellington’s environmentally conscious market, are increasingly seeking eco-friendly homes. Many are willing to pay more for properties that offer lower utility bills, healthier living environments, and align with their values.
4. Future-Proofing Against Regulation
As New Zealand’s regulatory landscape evolves, green certifications help ensure compliance with current and future standards, reducing the risk of costly retrofits or penalties down the line.
5. Enhanced Marketability
Certified properties stand out in listings, attracting more enquiries and allowing landlords to differentiate their rentals in a crowded market. Third-party certification provides transparency and credibility, reassuring tenants and investors alike.
