Te Kaha – One New Zealand Stadium

October 30, 2025

Christchurch, New Zealand


We were honoured to provide the precision-engineered ductwork solutions for Te Kaha, a landmark multi-use arena designed to revitalise Christchurch’s sporting and cultural heart.


Our systems support the complex HVAC infrastructure required for a venue that accommodates tens of thousands of spectators, while meeting stringent expectations around natural ventilation, indoor air quality and resilience.


By integrating our high-performance air-ducting within a mechanically-efficient, future-focused building envelope, our contribution helps deliver a world-class facility that stands for durability, sustainability and community pride.

Custom steel ducting fabrication is the process of manufacturing HVAC ductwork to the exact dimensions and performance requirements of a commercial building. It improves installation efficiency, supports better airflow, reduces onsite modifications, and helps contractors deliver projects on time and within budget. When commercial HVAC projects demand precise performance, fast installation, and reliable long-term operation, custom steel ducting fabrication becomes one of the most important parts of the mechanical system. Unlike standard off-the-shelf ductwork, custom fabrication produces ducting that is designed and manufactured specifically for a project's building layout, airflow requirements, equipment, and installation sequence. For commercial HVAC installation contractors, this means fewer compromises, fewer site modifications, and greater confidence that the ductwork will fit first time.
