In August 2022, the Mangamuka Gorge was affected by numerous large slips that severed this vital Northland transport link.

Now, this remote 13-kilometre stretch of road bristles with over 200 sensors, forming one of the most concentrated sensor networks in the Aotearoa, New Zealand.

This sensor network is designed to tirelessly detect ground movement, among other parameters, to safeguard workers restoring this necessary transport link. 

Large areas of the road corridor across Hawkes Bay and Gisborne were affected in February 2023 following Cyclone Gabrielle.

WSP Instrumentation experts have provided the ability for real-time measurement from the most remote locations on SH2 and SH35 to assist with the on-going management of temporary and damaged bridge performance and landslides on critical infrastructure.

This enables the timely and appropriate response as conditions change.

The steep cliffs that lie between coastal villages on Wellington's Kāpiti Coast have a history of slipping and instability. In heavy rain, this has resulted in disruption and damage to the rail line beneath.

Thanks to our instrumentation experts,  KiwiRail now benefits from the latest in slope monitoring technology enabling the removal of train speed restrictions.

This monitoring system has been designed to minimise the potential risk of landslips and ground movement impacting trains and passengers.
