What We Do ·
Traffic Signals
Traffic signals are essential infrastructure that keep people moving safely through our transport networks. CSL supplies, installs, maintains, and upgrades signal systems for councils, contractors, and transport authorities across New Zealand.
Capability Overview
Traffic signal infrastructure forms the foundation of every transport network. While often taken for granted, signal systems play a critical role in managing vehicle, pedestrian, and cyclist movements safely and efficiently.
With decades of experience in traffic signal delivery, CSL provides product supply, installation, maintenance, renewals, and upgrade services across New Zealand. From individual intersections to network-wide maintenance contracts, we help ensure critical transport infrastructure continues to operate reliably every day.
Traffic signals have been part of CSL's DNA since the original CSL Traffic business was established in 1991.
Today, that experience supports everything from new signal installations and network upgrades to long-term maintenance contracts and asset renewals. While transport technology continues to evolve, reliable signal infrastructure remains the foundation that keeps communities connected and moving safely.
