Benefits
Secure
KOROK® panels consist of a steel shell filled with aerated concrete. Having a solid wall provides peace of mind to occupants’ in the knowledge that they are physically separated from neighbouring dwellings.
Quiet
KOROK® panels offer superior mass over traditional timber and plasterboard or equivalent systems resulting in enhanced sound attenuation, particularly in the more invasive lower frequencies. This means that residents are comfortable in their own space without the intrusion of noise from other dwellings.
Flexible
KOROK® panels provide all the fire protection you need. You can run electrical and plumbing services on an intertenancy wall, without the need for special penetration seals around each pipe or light switch. This allows you the flexibility of placing a TV and kitchen where you want, and the ability to hang pictures on the wall without compromising the fire and acoustic resistance of the intertenancy wall.
Fast
KOROK® panels are fast to install. Installation can be done by a three-man team, with no need for cranes. Made to measure means there’s no on-site waste and because the walls can be re-positioned or recycled, it’s a sustainable way of building.
Case studies
Costco Wholesale Looking Good and Standing Strong

Costco is the world’s second largest retailer after Walmart, with over 273,000 employees and 803 store locations worldwide. Originally founded in Seattle in 1983, it had net sales of $163B in 2020.
Built on a difficult site and during a pandemic, the first Costco store opened in New Zealand in October 2022.
Costco Auckland is located at 2 Gunton Drive, Westgate in the suburb of Massey and is part of the Westgate Shopping Centre, one of New Zealand’s largest master planned urbanisation projects and the hub for the large and rapidly expanding communities of Auckland’s Northwest.
The building comprises of 15,000m² of ground floor retail, and overhead parking for over 800 cars. The development includes a fuel station, tyre centre, food court, optometrist, and hearing aid services along with groceries and homewares.
It is a very solid structure — steel and concrete.
KOROK brought many benefits to the project, the key one being high quality pre-finished internal walls, providing a clean aesthetic. The single-panel system ensured a fast install. Underlying these benefits is great fire and acoustic performance.
KOROK panels have been used:
As separation walls between the entry and main shop — ColorSteel Titania, vertical 7.2m high.
Around the main lifts — ColorSteel Titania.
For the fire escape stairwells — in galv and left visible.

Hobsonville Point Fire
On 1st September 2017 a large fire ravaged a townhouse at Hobsonville Point.
Hobsonville Point is a master-planned community being developed on 167 hectares of upper Waitemata Harbour coastal land formerly home to the Hobsonville air base. Development has been ongoing since 2011. On 1st September 2017 a large fire ravaged a townhouse in the final stages of construction. The fire was so hot that adjacent traffic lights melted. Thousands of tons of water were used to quell the fire. Luckily for attached homes, KOROK fire and acoustic wall had been used. As John Booth, Assistant Area Commander for the New Zealand Fire Service said “…the fire walls did what they are designed to do – and that is stop the spread of fire.” These photos clearly show how the house with the fire has burned away, leaving the firewalls in place.

Air Traffic Control Tower
No, your eyes aren't playing tricks on you. This is what the new air traffic control tower at Wellington airport looks like.
In August 2018 Wellington airport got a new traffic control tower, to support the more than 97,000 flights that arrive and depart Wellington Airport each year.
Built to meet 100 per cent of the building code for a structure of its importance level, the tower is one of New Zealand’s safest buildings. Thirteen base isolators have been installed within its foundations to provide a high level of resilience against earthquakes.
The tower is 32 metres above ground level, giving the controllers working in the tower panoramic views across the airfield.
Tūranga, Christchurch Library
Christchurch Central Library closed on the 22nd February 2011. This was the day of the Christchurch earthquake which killed 185 people.
Tūranga is the main public library in Christchurch, New Zealand. It opened in October 2018 and replaced the nearby Christchurch Central Library that was closed on the day of the 2011 Christchurch earthquake.
The replacement library was designed by both Architectus, a New Zealand architecture firm, and Schmidt Hammer Lassen, an award-winning Danish architecture firm. The building's design is inspired by the golden hues reflected upon the Port Hills, which are an important part in Christchurch's cityscape.
Hoyts Cinema Complex
A great new multiplex cinema coming in South Auckland. Ever wondered why you can't hear the movie playing on the screen next to yours?
Ormiston Hoyts Cinema Complex is part of a $200 million shopping mall being built in Ormiston, a new town in the south Auckland suburb of Flat Bush. The cinema will have eight theatres.
Theatre walls are made from a double layer of 78mm KOROK® panels with a large gap in between and acoustic batts to prevent sound travelling.
