A Landmark Development with a Strong Foundation
The Catalina Bay Apartments were built on a historically significant site, once home to a Royal New Zealand Air Force base. The design of the development pays homage to this heritage while providing modern, high-quality residences.
Despite construction challenges such as extreme weather events and pandemic-related delays, the project was successfully completed in July 2024, thanks to the collaborative efforts of the client, consultants, and contractors. More than 2,200 workers contributed to this impressive 28-month build.
KOROK® – Setting the Standard in Fire and Acoustic Protection
KOROK is proud to have contributed to this landmark residential development, providing solutions that ensure safety, comfort, and efficiency. Our fire and acoustic wall systems continue to set the benchmark for high-performance construction in New Zealand’s premium apartment projects.
KOROK supplied all fire and acoustic wall systems for the project, including:
- Lift Shafts, Risers, and Ducts
- Intertenancy Apartment Walls
Our systems were chosen to enhance fire safety, acoustic insulation, and construction efficiency in this high-end residential development.
KOROK® for Lift Shafts, Risers, and Ducts
KOROK® panels provided an efficient and robust solution for the lift shafts, risers, and ducts at Catalina Bay, offering multiple advantages:
- Single-side installation: Eliminates the need for scaffolding inside shafts, accelerating the build process.
- Pre-weather installation: Our panels can be installed before the building is fully enclosed, preventing water ingress through open shafts and risers.
- Superior fire and acoustic performance: Ensuring compliance with New Zealand’s strict building codes for safety and comfort.
KOROK® for Intertenancy Apartment Walls
Each apartment in Catalina Bay was designed for privacy and luxury. KOROK® intertenancy walls played a crucial role in achieving this by delivering:
- Proven fire-rated protection and acoustic insulation, ensuring a safe and peaceful living environment.
- Solid wall construction, enhancing security and long-term durability.
- Faster installation times, reducing project timelines and labor costs.
- Sustainable solutions, minimizing construction waste and contributing to the development’s Homestar-7 sustainability rating.
KOROK Systems used in this project
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.
