About the project
This 5km section of the Northern Pathway starts in Westhaven, travels across the Waitemata Harbour and continues onto Akoranga. This section is the critical link required to connect central Auckland and the North Shore, providing choice for how people travel to work, access services or connect with family and friends.
This section was previously known as SkyPath/Auckland Harbour Bridge Shared Path and SeaPath. Both components have now been combined for delivery of the Northern Pathway.
Detailed Business Case
This section was originally conceived as two separate projects and the Transport Agency completed individual Detailed Business Cases (DBC).

The preferred option for the Auckland Harbour Bridge component is a five-metre-wide pathway, built on new separate trestle legs and pier brackets, attached to the existing concrete piers on the eastern (southbound) side of the Auckland Harbour Bridge.
The pathway will be separated from the Auckland Harbour Bridge’s existing southbound extension bridge (known as the southbound clip-on) to allow access for maintenance.
This solution meets the future demands of bridge users and preserves the structural integrity of the Auckland Harbour Bridge.
Benefits of this solution:
- Because it is attached to the bridge piers rather than the clip on, it will both preserve the capacity of the existing clip on and accommodate user loading comfortably
- It won’t move up and down like the existing southbound clip-on does under vehicle loading, as it’s not attached to the clip on
- The architectural concept and material are sympathetic to the shape and design of the existing bridge
- The five-metre width allows for separation of modes which will be worked through in the next stage of the project – with the rapid changes in active modes and micromobility, the separation/shared use operation continues to be evaluated as the project progresses
- Three pause points which will allow users to move out of the through traffic and take a breather.
The land component of the pathway between Sulphur Beach Reserve and Akoranga is expected to be four metres wide. At a few locations the pathway may have to narrow due to areas of cultural significance and protected trees
Geotechnical investigations have started in the project area to provide further information as part of the necessary planning and technical work.
In 2020, the Transport Agency will be talking more with partners, stakeholders and community about this section of the Northern Pathway.
We will be starting the process to secure the approvals required for this section in mid-2020. The soonest construction could begin is early 2021, with mid-2021 potentially being a most likely, subject to the approval process. It is expected to take about two and a half years to complete construction.
