Now that the Ara Tūhono - Pūhoi to Warkworth motorway is open, NZ Transport Agency Waka Kotahi (NZTA) and Auckland Transport have been working together to change the status of the main road that runs from Pūhoi to Warkworth, from a state highway to a local road. This process, known as revocation, transfers responsibility for the old state highway to Auckland Transport.

We’ve been working hard with Auckland Transport to have the road must be fit for purpose in relation to its transport functions. Fit for purpose means that at the time of handover the revoked section of state highway will provide a level of service equivalent to other roads providing a similar function within the local road network. Some of the works that have taken place since early road opening including line marking and barrier installation along Hibiscus Coast Highway.
Traffic volumes on this corridor have reduced since the motorway opened but it remains a key route for local traffic and those wishing to use the toll-free Hibiscus Coast Highway route as there is no southbound exit from the new motorway before the Northern Gateway Toll Road.
Renaming the old SH1
As part of the 'revocation' process to make SH1 a local road, it will lose its classification as a state highway and will be renamed. It can no longer be called a state highway for address and identification purposes. This process is managed by Auckland Transport.
As of 1 July 2024 the responsibility of the Old SH1 has transferred to Auckland Transport as Pōhuehue Road.
