Heavy maintenance (dig outs) underway during the SH1 Brynderwyn Hills closure. ‘Dig out’ repairs involve removing and replacing the material beneath the road surface to restore strength and support for traffic.

Kia ora and welcome

Welcome to the Northland state highway maintenance roadworks update.

Meet the Multipatcher

This is a Multipatcher – an all-in-one machine that allows roadworkers to quickly repair potholes and road edges, reducing disruption to your travel.

One of the advantages of the Multipatcher is its ability to perform multiple types of repairs at the same time, saving both time and costs. As it moves along the road, the driver scans for defects like potholes, sprays a hot mix-like solution, applies a protective layer of dry surface and presses the material in – leaving a road-ready surface you can travel over immediately. The entire process can take as little as a minute.

The Multipatcher even has built-in traffic management boards, further enhancing safety and efficiency.

You’ll see it out on State Highway 16 (SH16) Kaukapakapa this coming week, repairing sections of the road. We use the Multipatcher across Northland’s state highways year-round to help keep the roads safe and smooth.

Before and after: road repairs with the Multipatcher.
