UPDATE: 27 September 2024
One additional night closure is required to complete the below works on Sunday 29 September between 8pm and 5am.
It is a much shorter detour, with people heading north to be detoured after the Johnstone Hill Tunnels at Puhoi ramp and southbound via Old State Highway 1, rejoining the motorway at the Pūhoi ramp.
It is expected that this will add approximately 3-5 mins to the journey time.
These works are weather-dependent and subject to change and significant rain and high winds may require rescheduling to Monday night (30 September).

NZ Transport Agency Waka Kotahi is advising motorists that overnight closures on State Highway 1 (SH1) in both directions from Pukerito roundabout near Warkworth to Silverdale will take place for 5 nights between Sunday 22 September and Thursday 26 September between 8pm and 5am.
All vehicles will be detoured via Old State Highway 1 (Pōhuehue Road) and Hibiscus Coast Road in both directions.
This work will combine essential maintenance and finishing works on the Ara Tūhono – Pūhoi to Warkworth motorway and the Highgate Bridge project which will provide a link for the community between John Fair Drive in Milldale to the Highgate Business Park and on to Silverdale and Millwater.
These works are taking place overnight to reduce the impact on road users.
Please note that these works are weather-dependent and subject to change. Significant rain and high winds may require rescheduling to the next suitable night.
Motorists are urged to plan ahead and check the NZTA Journey Planner before heading out.
