BNZ Place: A Testament to Innovation and Sustainability
After nearly four years of design and construction, BNZ Place at 1 Whitmore Street in Wellington is officially open. This 12-storey, 17,000m² building, a collaborative effort between Studio Pacific Architecture and Jasmax, epitomizes practical and purposeful workplace design, combining sustainability, wellbeing, and functionality.
BNZ Place is one of the most seismically resilient buildings in New Zealand, featuring base isolation to protect against significant structural damage during earthquakes. Raised on a plinth to minimize flood risks and supported by piles extending 60 meters below ground, the building exceeds seismic strength requirements with an NBS rating above 180%.
Innovative Features and Sustainability
Targeting a 5 Green Star As-Built rating, BNZ Place incorporates high-performance solar control glass, energy-efficient systems, and a structural steel diagrid. Efficient floorplates, a double-height entry lobby, inter-floor stairs, and a rooftop courtyard contribute to its state-of-the-art design.
KOROK’s Contribution
KOROK played a crucial role in the construction of BNZ Place by supplying fire and acoustic walls for lift shafts, risers, and ducts. KOROK panels offer significant advantages over traditional construction, as they can be installed from one side only, eliminating the need for scaffolding inside shafts and reducing construction time and costs. Additionally, KOROK panels can be installed before the structure is watertight, preventing water ingress through open shafts.
A Collaborative Effort
The project involved collaboration with various stakeholders, including Newcrest LP, the developer behind the building. CEO Dan Huggins emphasized BNZ’s commitment to Wellington and its future. “BNZ Place reflects our commitment to the city and our vision for the future. We are thrilled to share this vibrant and innovative space with our customers, colleagues, and the people of Wellington,” he said.
BNZ Place at 1 Whitmore Street symbolizes resilience, innovation, and sustainability. With its doors now open, it stands as a testament to collaboration, forward-thinking design, and a commitment to a better future for Wellington.
KOROK is proud to have supplied the critical fire and acoustic wall systems for the Auckland Film Studio and Sound Stage project. Designed by Ignite Architects and built by Haydn & Rollett Construction, this facility sets a new standard in the New Zealand cinema industry.
Our 78mm KOROK panels Gen 2 were chosen for their superior fire and sound-rated properties, achieving a Noise Criterion rating below NC-20. This was crucial in ensuring optimal recording conditions, despite the studios’ proximity to urban noise sources like Auckland’s western rail line.
Sustainable Design and Construction
The project has been awarded a 4 Green Star As-Built rating, recognizing its sustainable design and construction practices.
KOROK is honoured to contribute to a project that not only pushes the boundaries of film studio design but also promotes sustainability and economic growth in Auckland. We look forward to seeing the long-term benefits this project will bring to the local community and the entertainment industry.
The Bayfair Cinemas project is part of a $115 million development that marked the introduction of United Cinemas to New Zealand. United Cinemas, a prestigious Australian-owned chain, has been a leader in the industry since 1987. Known for its luxury cinema experience, United Cinemas operates 46 theatres across Australia, and Bayfair Cinemas in Mount Maunganui is its first venture in New Zealand. The complex includes seven state-of-the-art screens, featuring the region’s largest screen with Dolby Atmos Digital Sound, creating an unmatched cinematic experience.
KOROK® systems were selected for this project to provide industry-leading acoustic performance. Our 78mm KOROK® panels were installed throughout the cinema complex, ensuring superior soundproofing between screens and public areas. This acoustic control is essential for a seamless and immersive movie experience, eliminating external noise and maintaining sound quality within each theatre.
KOROK® is recognized as the number one choice for soundproofing in New Zealand cinemas, thanks to our ability to deliver fire-resistant, durable, and cost-efficient wall systems that also meet the high acoustic demands of modern theatres.
Why Choose KOROK® for Cinemas?
Superior Acoustic Control: Our panels are engineered to significantly reduce noise transmission between spaces.
Fire-Resistant Performance: KOROK® systems comply with stringent fire safety regulations, ideal for public spaces like cinemas.
Cost-Efficient Installation: KOROK® panels can be installed quickly, reducing both time and labor costs.
The Bayfair Cinemas project is a showcase of KOROK®’s commitment to delivering top-tier acoustic and fire-rated solutions for high-performance environments like cinemas.
Hoyts Cinema Complex, – KOROK® Wall Systems in Action
The Ormiston Hoyts Cinema Complex is part of a large shopping mall development in South Auckland’s Flat Bush. With eight theatres, the project required effective soundproofing to enhance the cinema experience.
KOROK® Panels for Acoustic Performance
The theatre walls feature a double layer of 78mm KOROK® panels with a gap filled with acoustic batts, designed to prevent sound from travelling between theatres. This setup ensures clear and uninterrupted sound for moviegoers.
KOROK® wall systems are known for their acoustic properties, making them a common choice for cinemas in New Zealand. These panels help manage sound, offer fire protection, and are straightforward to install, meeting both safety and performance needs.

KOROK® 78mm galv panels are precision rollformed from high-quality zinc-coated steel strips. The steel used for our shells meets the AS/NZS1397:2001 standard, ensuring consistent strength and durability. Each panel features a base metal thickness of 0.4 mm B.M.T. with a Z275 zinc coating, enclosing a lightweight aerated concrete core. This combination delivers a nominal weight of just 10.2 kg per lineal metre, making KOROK® panels easy to handle and install while maintaining exceptional structural performance.
Our panels are designed for versatility and high performance, offering superior fire and acoustic ratings for a wide range of applications. They provide fast, efficient installation with minimal on-site modifications, reducing labour costs and program delays. The lightweight nature of KOROK® panels also eases transport and handling, particularly on multi-storey construction projects.
Backed by over 20 years of experience, KOROK® panels are BRANZ-appraised, Kiwi-owned, and widely trusted across New Zealand for projects ranging from residential developments to complex commercial constructions. Our systems are designed to simplify installation, maximise safety, and deliver long-lasting performance, making KOROK® the preferred choice for builders, architects, and developers seeking reliable fire and acoustic wall solutions.
Fire and Acoustic Rated Wall Systems for Shafts, Risers, and Ducts
KOROK® fire and acoustic rated wall systems offer superior solutions for lift shafts, risers, and ducts. Lift shafts require fire and acoustic rated protection to ensure building safety. With our innovative panel design, you can install from one side only, eliminating the need for internal scaffolding and significantly reducing construction time and costs.
Key Advantages:
Single-side installation: No scaffolding required inside the shaft, speeding up the construction process.
Fire and acoustic performance: Our systems provide high-level fire resistance and acoustic insulation, ensuring safety and comfort. For lift shafts, this fire and acoustic rated protection is critical.
