KOROK® was involved in the construction of a dual-branded hotel in Auckland’s Central Business Precinct. Located at the corner of Albert and Wyndham Streets, this project, led by Icon NZ, began in 2019 and was completed in December 2021. The VOCO-HIE development is a 38-story building, standing approximately 135 meters tall, making it one of New Zealand’s tallest structures. The building offers expansive views across Waitemata Harbour and Mount Eden, featuring a modern design.
A 4-story glazed podium with separate entries for both hotels.
Guest services such as an all-day restaurant, bar, fitness center, and retail spaces.
294 Holiday Inn Express rooms on the lower floors.
200 VOCO Hotel rooms on the upper floors.
The VOCO brand, chosen by global hotel operator IHG, emphasizes sustainability through initiatives like recycling plastic bottles for bedding and using honey from onsite bees. The Auckland VOCO hotel continues these practices, alongside the ‘Me Time’ concept focusing on premium beds, superior showers, user-friendly technology, and innovative lighting.
KOROK®’s Contribution
KOROK® provided high-performance fire and acoustic wall systems for the VOCO-HIE development. Key highlights include:
Fire Protection: KOROK® systems offer up to a 2-hour fire rating, ensuring strong fire safety.
Acoustic Performance: The systems exceed the minimum STC 55 rating for hotels, achieving an STC 63 rating, ideal for ensuring a quiet environment for guests.
Design and Installation: KOROK®’s interlocking panels simplified and sped up installation, reducing labor costs and construction time. The panels’ clip-together design allowed for easy installation by a small crew, with comprehensive installation guides and on-site training provided.
Space Efficiency: The small footprint of KOROK® panels maximized usable floor space, offering developers greater flexibility in building design and planning.
Environmental Commitment
KOROK® panels were manufactured in New Zealand from locally sourced materials and were custom-made to minimize waste. They are fully recyclable and reusable, aligning with the sustainable ethos of the VOCO brand.
Collaboration and Innovation
KOROK® and Icon NZ collaborated closely to devise solutions for lift shafts and staircases, reflecting a commitment to quality and innovation in construction.
KOROK® was proud to contribute to the VOCO-HIE dual-branded hotel project, providing high-performance fire and acoustic wall systems that supported the building’s design and sustainability goals. This project showcased KOROK®’s dedication to quality and innovative building solutions.

Intertenancy Apartment Systems
At KOROK® we have developed a new series of KIR KOROK® Intertenancy Residential Walls that remove the need for linings in the ceiling plenum whilst maintaining fire resistance and acoustic control performance.
Wellington Airport welcomed a new state-of-the-art air traffic control tower in August 2018, designed to handle the airport’s demanding operations with over 97,000 flights annually. Standing 32 metres tall, the tower provides panoramic views across the airfield, ensuring air traffic controllers have optimal visibility to manage air traffic safely and efficiently.
This iconic structure is one of New Zealand’s safest buildings, meeting 100% of the building code for its importance level. The tower’s base includes 13 advanced base isolators to deliver superior earthquake resilience, a critical feature in Wellington’s seismic environment.
KOROK® was proud to contribute to this project, supplying 78mm fire-rated acoustic panels for the lift shafts, risers, and ducts. Our systems are specifically designed to streamline construction and improve safety on site. By allowing installation from just one side, scaffolding inside the shaft is not required, reducing both construction time and costs.
Our panels offer superior fire resistance, acoustic performance, and seismic resilience, making them the ideal solution for high-importance structures like the Wellington Airport control tower.
Why KOROK®?
Efficient Installation: No need for internal scaffolding, speeding up project timelines.
Superior Fire Protection: KOROK® systems ensure compliance with fire safety regulations.
Acoustic Performance: Helps to minimize noise pollution in critical areas like lift shafts and risers.
Seismic Resilience: Engineered for enhanced stability in earthquake-prone zones.
The Wellington Airport control tower is a landmark project, showcasing KOROK®’s capabilities in delivering advanced, resilient building systems for critical infrastructure.

Lift Shafts, Risers, Ducts
For lift shafts and duct walls, KOROK® offers significant advantages over traditional construction. As panels can be installed from one side only, there is no requirement to construct scaffolding inside the shaft, greatly reducing construction time and costs.
KOROK Fire and Acoustic Wall Systems at Tūranga Library, Christchurch
KOROK proudly contributed to the Tūranga Library project in Christchurch, New Zealand, which opened its doors in October 2018. As a replacement for the Christchurch Central Library, which was damaged during the 2011 Christchurch earthquake, Tūranga stands as a modern architectural masterpiece. Designed by New Zealand firm Architectus in collaboration with the award-winning Danish firm Schmidt Hammer Lassen, the library’s striking design reflects the golden hues of Christchurch’s Port Hills. KOROK’s fire wall and acoustic wall systems were installed in the building’s lift shafts, risers, and ducts, providing superior fire protection and sound insulation to support the library’s functional and safety needs.

Lift Shafts, Risers, Ducts – Fire and Acoustic Rated Protection
KOROK® fire and acoustic rated wall systems offer superior solutions for lift shafts, risers, and ducts. 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.
Pre-weather installation: KOROK® panels can be installed before the building is watertight, protecting against water ingress through open shafts and risers.
