Highway roadworks in North Canterbury to impact traffic

NZ Transport Agency Waka Kotahi | 8 Jan 2026 12:04pm | Canterbury

Important roadworks may mean some disruption for road users travelling on State Highway 1 north of Christchurch from later this month.

From next week, State Highway 1 between Amberley and Glasnevin in North Canterbury is scheduled to be closed to northbound traffic for road construction work between 6am and 6pm, Monday 12 January to Friday 30 January. While the southbound traffic lane will still be operating, a 30km/h temporary speed limit restriction will be in place and people should expect delays of up to 15 minutes while this work is happening.

A detour will be available to northbound traffic: road users should turn left on to Douglas Road, follow straight onto Mount Brown Road, then turn right onto Georges Road, and then left back onto SH1.

The work will be dependent on various factors such as the weather, and it may be postponed or rescheduled at short notice. If this happens, notification will be provided.

We thank people for their patience and understanding as this work is carried out to improve the highway network for road users.
