Auckland Transport (AT) will be undertaking seismic strengthening below Quay Street between Princes Wharf and Marsden Wharf. This will be the first step in the revitalisation of Quay Street.
Project status: Construction mid-2019 to mid-2020
Project zone: Central
To protect Quay Street and the utility services that run beneath it, seismic strengthening of the 100-year-old seawall is needed between Princes Wharf and Marsden Wharf. Getting these foundations sorted will secure the area for the next 100 years.
The seawall forms the harbour edge of an historic land reclamation, which supports Quay Street and the services contained in the road corridor. The first sections of this reclamation were built between 1879 and 1886 along what is now Quay Street west of Britomart, and also east of Britomart, parallel to Beach Road. Subsequent sections were added after the turn of the 20th Century.
Without the Seawall, significant parts of downtown Auckland would be under water.

How the work will be done
Strengthening will be completed in four sections between Princes Wharf and Marsden Wharf.
Three different methodologies will be used:
- Palisade wall.
- Jet grouting.
- Anchoring the existing seawall.
