Parakiore Recreation and Sports Centre stands as one of Aotearoa New Zealand’s most ambitious community and high-performance sporting developments – a 32,000m² hub designed to support everyday recreation through to elite national and international events. Designed by Warren and Mahoney in association with Peddle Thorp and MJMA, and delivered on behalf of Crown Infrastructure Delivery for Christchurch City Council, the project required building systems that could perform at the highest level – structurally, acoustically, and in fire protection. KOROK was proud to contribute to this nationally significant development, supplying 300m² of KOROK® 78mm Galv Panel for key internal fire and acoustic separations within the complex.
The Challenge: Performance Across Scale, Safety & Sound
A building of this scale brings significant fire-safety and acoustic requirements. With large wet and dry zones, interconnected public spaces, high-performance training areas, and major event facilities, the project team required internal wall systems that delivered:
High fire resistance for critical separation zones
Reliable acoustic performance to manage noise transfer between pools, courts, fitness areas, and specialist spaces
Lightweight construction to integrate efficiently into the steel-driven structural design
Durability and compliance within a major civic facility expected to host two million visitors annually
This combination of acoustic control, fire protection, and constructability made KOROK’s systems an ideal fit.
KOROK® Solution
KOROK supplied 300m² of KOROK® 78mm Galv Panels, providing a robust fire- and acoustic-rated solution for internal separations within the facility. Why the 78mm Galv Panel Was Chosen:
High-Performance Fire Rating. Manufactured from zinc-coated steel shells conforming to AS/NZS1397:2001 with a Z275 coating, the panels offer reliable and tested fire protection essential for a public facility of this scale.
Excellent Acoustic Control. The aerated concrete core delivers strong airborne sound reduction — critical in a building that includes hydroslides, aquatic halls, gym spaces, and nine active courts.
Lightweight & Efficient to Install. At just 10.2kg per lineal metre, the 78mm panel is easily handled on a complex construction site, allowing rapid installation and smoother coordination with other trades.
Durability for Heavy-Use Environments.Designed to stand up to the demands of high-traffic public recreation centres and high-performance training areas.
The KOROK system contributed to meeting the project’s stringent fire-safety requirements while supporting the acoustic conditions necessary to create a functional and enjoyable environment across vastly different activity zones.
KOROK’s contribution helped ensure safe, durable, and high-performing internal environments within one of New Zealand’s most significant sport and recreation developments. The Parakiore facility will host community users, school groups, local clubs, and elite athletes alike – supported by dependable fire and acoustic separation systems designed to perform over decades of intensive use. KOROK is proud to support a project that not only enhances Christchurch’s sporting infrastructure but also delivers long-term social, economic, and recreational benefit for the region.
KOROK® has 2-way fire-rated wall systems for fire separation of Scissor Stairs or any Stairs.
Our innovative KOROK® Scissor Stair wall systems are BRANZ-tested and Warringtonfire-assessed, ensuring compliance with New Zealand’s fire safety standards. These systems are rated up to a Fire Resistance Rating (FRR) of -/120/120, offering robust protection for critical building areas. KOROK® Scissor Stairs Systems cater to most common scenarios requiring fire resistance in stair configurations. These walls are constructed using 78mm thick, horizontally and/or vertically oriented KOROK® panels, designed to fit seamlessly between two independent stair stringers in scissor stairs configurations. The systems feature self-supporting, non-load-bearing walls that can be built using horizontally or vertically stacked panels, or a combination of both. This flexibility ensures adaptability to a wide range of building designs.
Key Benefits of KOROK® Scissor Stairs Fire-Rated Wall Systems:
Two-way fire protection: Rated up to FRR -/120/120 for comprehensive fire separation.
No height limitations: KOROK® walls can be installed without restrictions on wall height, in both horizontal and vertical configurations.
Structural simplicity: No additional structural support required beyond attachment to stair landings and stair stringers.
Fast, efficient installation: Lightweight interlocking panels make installation faster and more cost-effective compared to conventional systems.
KOROK® Scissor Stairs wall systems combine fire safety, acoustic performance, and cost efficiency, making them the ideal choice for builders and developers.
KOROK Panels at Work in Raglan: Quieting the Glass Recycling Hub
We’ve just wrapped up a project at the Xtreme Zero Waste recycling center in Raglan, where we installed a “box” using our fire and acoustic panels around their glass recycling facility. The goal? To keep the noise down from the glass recycling process. The crew at Xtreme Zero Waste couldn’t be happier, saying, “The box looks awesome and works well.” It’s great to see our panels doing their job, making the space quieter and more comfortable for everyone involved. We’re stoked to have been part of this project and to see our panels making a difference right here in Raglan.
Costco Auckland, Standing Strong with KOROK® Wall Systems
Costco, the world’s second-largest retailer, opened its first New Zealand store in October 2022 at 2 Gunton Drive, Westgate, Auckland. Part of the expansive Westgate Shopping Centre, this new 15,000m² retail space features overhead parking for over 800 vehicles and includes essential services like a fuel station, tyre centre, food court, optometrist, and hearing aid services. This store is a key addition to the rapidly growing Northwest Auckland community, built on a challenging site during the COVID-19 pandemic. As a solid structure made of steel and concrete, Costco Auckland stands as a durable retail hub that incorporates the high-performance KOROK® wall system.
KOROK® supplied 78mm fire-rated acoustic panels (GEN 2) for several key areas of the Costco Auckland project, delivering fast installation and exceptional quality. Our system provided pre-finished internal walls, ensuring a sleek and clean aesthetic, combined with robust fire safety and acoustic insulation.
Key Areas Where KOROK® Panels Were Used:
Separation Walls: Between the entry and main shop (7.2m high, ColorSteel Titania finish)
Lift Surrounds: ColorSteel Titania panels installed around the main lifts
Fire Escape Stairwells: Galvanized panels left visible for fire compliance
Why KOROK® for Warehouses and Retail?
