Unmatched expertise
For over six decades we’ve engineered networks that underpin New Zealand’s broadcast, maritime and critical-communications landscape. Our engineers design the very systems that monitor nearly a quarter of the world’s oceans, while our structural engineers build towers and infrastructure to exacting standards. Today, we’ve expanded into consulting across cyber-security, cloud and connectivity, bringing deep specialist knowledge to everything we solve. With Kordia, you access a team of trusted experts who know how to tackle complexity and deliver systems that work.
Robust reliability
Our networks are built to endure. Many of our major transmission and communications sites are rated to “Level 4 importance”, designed to remain operational during severe weather, earthquakes and outages. From our nationwide field engineers and technicians to innovative backup systems (digital microwave radio, diverse links and more), we deliver resilient connectivity across New Zealand. We don’t just build networks - we maintain, monitor and continuously improve them so your business stays connected when it matters most.
24/7 x 365 service
Critical business communications don’t sleep. That’s why our Security Operations Centre (SOC), Network Operations Centre (NOC) and Maritime Operations Centres (MOC) operate around the clock, every day of the year. From cyber-threat detection and response to real-time network monitoring and safety-of-life-at-sea communications, we keep eyes on glass so you don’t have to. When seconds count, our teams are ready - ensuring your systems are protected, supported and always on.
