April 2026 – Meidoor, a global leader in high-performance fenestration solutions, announced today that its core aluminum window and door products have successfully passed a comprehensive suite of New Zealand’s mandatory testing and certification processes. The company has officially obtained the CodeMark certification, alongside compliance with NZS 4211:2008 and AS/NZS 4284 standards – key benchmarks for accessing New Zealand’s construction market. This achievement confirms Meidoor’s products meet the rigorous safety, energy efficiency, and durability requirements of the New Zealand Building Code (NZBC), marking a significant milestone in its expansion into the Oceanian market.
New Zealand’s construction industry enforces some of the strictest fenestration standards globally, driven by its unique climate conditions – from coastal high-wind zones to varying temperature extremes. The certification process, conducted by an ILAC-accredited laboratory, evaluated Meidoor’s products across multiple critical performance metrics mandated by NZBC Clause E2 (External Waterproofing) and Clause E3 (Internal Moisture Resistance).
Key highlights of Meidoor’s certification results include:
Compliance with NZS 4211:2008: Meidoor’s windows and doors achieved an Air Leakage Factor (ALF) of less than 0.8 m³/(h·m²), exceeding the standard’s requirement of below 1.0 m³/(h·m²). This exceptional airtightness ensures minimal heat loss, reduces energy consumption for heating and cooling, and enhances indoor noise insulation – critical for New Zealand’s residential and commercial buildings. All certified units will bear the mandatory NZS 4211 label, specifying wind zone compatibility and performance grades as required by local regulations.
CodeMark Certification for Waterproofing & Durability: As New Zealand’s government-recognized compliance mark, CodeMark confirms Meidoor’s products meet strict waterproofing standards. During testing, the products withstood a simulated extreme weather test (50m/s wind speed and 150L/m²/h rainfall) without any water penetration, fully complying with NZBC Clause E2. Additionally, the products passed 10,000+ cycle durability tests, verifying the long-term reliability of hardware and sealing systems – a key requirement for mitigating New Zealand’s annual $200 million+ building leakage repair costs.
AS/NZS 4284 Compliance for Structural Performance: Meidoor’s anti-hurricane window and door series demonstrated structural integrity under ±5000Pa wind pressure, equivalent to resisting Category 12 hurricane conditions. The tests, which included static, dynamic, and cyclic wind load assessments, confirmed the products’ ability to withstand New Zealand’s harsh coastal and high-altitude wind zones. The use of 6063-T6 aluminum profiles and EPDM composite seals further ensured corrosion resistance and long-term performance.
Energy Efficiency Excellence: Meidoor’s certified products also met the Passive House Institute (PHI) energy efficiency criteria, with a U-value below 0.8 W/(m²·K). The optimized thermal insulation design, combined with Low-E glass options, allows for tailored Solar Heat Gain Coefficient (SHGC) values – adapting to New Zealand’s varying regional climate needs, from maximizing winter solar gain in southern regions to minimizing summer heat intake in northern areas.
“Earning New Zealand’s CodeMark and NZS 4211 certification is a testament to Meidoor’s unwavering commitment to global quality standards,” said Jay, General Manager of Meidoor. “New Zealand’s construction market values durability, energy efficiency, and compliance above all else – and our certified products are designed to exceed these expectations. This certification opens the door for us to partner with local builders, developers, and distributors, bringing our proven fenestration solutions to Kiwi homes and commercial projects.”
Industry experts note that CodeMark certification significantly streamlines project approvals for manufacturers, as certified products are automatically recognized as compliant with NZBC requirements. For Meidoor, this achievement builds on its existing global credentials – including ISO 9001:2015 certification and upcoming NAHB membership – reinforcing its position as a trusted international fenestration supplier.
Meidoor has already initiated discussions with New Zealand-based building material distributors to bring its certified products to the local market. The company plans to prioritize supply of its high-performance residential windows and the 150H Series Panoramic Sliding Door – both of which have been certified to meet New Zealand’s specific performance needs.
