New Building Product Standards Are Here – What Every Homeowner Should Know! 🔨
From 28 July 2025, the Ministry of Business, Innovation and Employment (MBIE) has introduced the Building Product Specifications (BPS) — a major update that defines how key building materials must perform to meet the New Zealand Building Code.
These new standards help ensure safer, stronger, and more energy-efficient homes — and they directly affect how your home is built or renovated.
What’s Changing and Why It Matters:
Timber Treatment & Durability
* Clear rules for how timber must be treated for different areas of the home — from subfloors and wall framing to exterior decks.
* Helps prevent rot, decay, and structural failure over time — especially in damp or exposed areas.
Windows, Doors & Glazing
* Must meet updated wind resistance and waterproofing standards based on your property’s wind zone.
* Safer glazing requirements for doors and balustrades to reduce risk from impacts or breaks.
Fire Safety Improvements
* New guidelines for insulation, cladding, linings, and fire doors to reduce the spread of fire in an emergency.
* Classifications for materials help designers choose the right products to meet fire safety codes.
Insulation & Energy Efficiency
* R-values (thermal resistance) must be proven through internationally recognised test methods.
* Ensures your insulation performs as promised – keeping your home warmer and more efficient.
Cladding & Wall Systems
* Stronger testing requirements for fibre-cement, EIFS systems, and fire-retardant timber products.
* Helps protect your home from weather and fire exposure.
