CodeMark Certified Windows and Doors in New Zealand – Fully Compliant & Council-Approved

When it comes to building or renovating in New Zealand, choosing compliant, high-quality products isn’t just a recommendation — it’s a requirement. Among the certifications that matter most in the New Zealand construction industry, CodeMark certification stands out. At ROPO, we are proud to offer a range of CodeMark certified uPVC windows and doors, aluminium windows and doors that meet the highest standards of safety, performance, and compliance.

In this blog, we’ll explain what CodeMark certification is, what it covers, showcase ROPO's certified products, and help you understand why choosing a CodeMark certified supplier matters for your project.

CodeMark is a voluntary building product certification scheme for Australia and New Zealand, designed to give builders, designers, and building consent authorities a high level of confidence in the products they use. Endorsed by MBIE (Ministry of Business, Innovation and Employment) in New Zealand, a CodeMark certificate means the product:

* Complies with the New Zealand Building Code (NZBC)

* Has been independently assessed and audited

* Is subject to ongoing quality assurance and testing

* Is legally binding: Local councils must accept CodeMark products as compliant when used as specified

In short, it removes the uncertainty around building consent approvals and streamlines your project’s compliance process.

CodeMark certification isn’t just a label — it is a rigorous and detailed compliance process that evaluates:

B1 Structure:NZS4211:2008 specification for Performance of Windows

B2 Durability

E2 External Moisture: NZS4211:2008 specification for Performance of Windows

F2: Hazardous Building Materials

G4: Ventilation

G7: Natural Light

H1: Energy Efficiency

The certification ensures that the windows and doors are not only fit for purpose but also designed to last in New Zealand’s diverse climate zones — from coastal environments to alpine conditions.

At ROPO, we are committed to delivering products that meet the strictest international standards. We’re proud that several of our aluminium and uPVC window and door systems have obtained CodeMark certification in New Zealand. These include:

Double-glazed aluminium windows and doors

Double-glazed uPVC windows and doors

Our windows and doors are tested against NZS standards, including AS/NZS2208 and NZS4211 and are backed by CodeMark certification to give our clients total peace of mind. With over 16 years of export experience and a strong focus on compliance, ROPO helps ensure your project proceeds smoothly — from design to council approval.

ROPO has successfully delivered high-performance windows and doors to numerous residential and commercial projects across New Zealand. Here are some highlights from our New Zealand Project Portfolio:

🏠 North Shore, Auckland

ROPO supplied white uPVC tilt & turn windows and fixed glazing units for this stunning home, located in a coastal area prone to strong winds and salt air. All windows were double glazed with laminated safety glass, meeting CodeMark and NZS4211 standards, ensuring long-lasting durability and insulation.

🏡 Christchurch Modern Villa

For a modern villa in Christchurch, ROPO provided thermally broken aluminium sliding doors and casement windows, optimized for both energy efficiency and seismic resilience. The CodeMark certification simplified council approval, while the Low-E glass improved energy performance in the colder South Island climate.

🏘️ Queenstown Lakeside Home

This high-end lakeside residence used a combination of floor-to-ceiling fixed glass windows and stacking doors, enhancing panoramic views while maintaining excellent weather resistance. ROPO's CodeMark certified systems were a key selection criterion due to the region's alpine conditions.
