Christchurch Stadium One

Delivering a large-scale sports stadium presents a unique set of challenges from tight construction timelines to complex structural demands and long-term durability requirements.

Following the Christchurch earthquakes, the need for a temporary stadium in 2012 required an incredibly fast turnaround. The facility was completed in just 11 weeks, accommodating 18,000 people with a build cost of $32 million.

Now, with the development of Christchurch’s new Stadium ONE, the challenge continued. While the design differs from previous projects, the scale of substructure concrete works, precision installation requirements, and need to stay on programme remain critical factors.

Canzac has played a key role across these projects by delivering proven, high-performance solutions tailored to large-scale concrete construction.

On the Christchurch Stadium One project, we pioneered the use of our Speedform® system, an innovation that has become a trusted solution over the years. With over 12,000 square metres installed to speed up the foundation construction process. The distinctive red formwork has been instrumental in supporting efficient and accurate substructure construction.

In addition, Canzac supplied over 7,000 anchors used to lift and position the precast bleachers and main staircase components. These bleachers totalling approximately 11 kilometres were manufactured offsite and installed with precision on-site.

We were also awarded the contract to seal the precast  bleachers using Convergent Pentra-Sil NL®, a treatment designed to harden and densify concrete elements, enhancing their durability.
