Ports of Auckland outfall upgrade project

This $40m project will significantly upgrade the downtown port area stormwater system, increasing its capacity to deal with flooding. The work will also extend the life of existing infrastructure and provide vital infrastructure for future growth.

About the stormwater improvement

The work involves installing a new 270m stormwater pipe.

The pipe will run from the south-eastern end of Quay Street (east of Spark Arena and west of a parade of shops and services at 8–14 Quay Street), and across the Ports of Auckland site.

It will then connect to an outfall to the sea.

When the new pipe is operating, repairs will be carried out on the existing stormwater culvert so that both systems can operate together.

Work started in October 2021 and will be completed by late 2023.

Traffic management on Quay Street

Every effort is being made to ensure that traffic on this busy commuter route can continue to flow without significant interruption.

All lanes will continue to be open:

Two general lanes travelling east.
Two-way cycle lanes.
Two general lanes travelling west.
A bus-only lane from 6am to 10am travelling west.

Traffic lanes will be shifted

For a short 200m section on Quay Street, all traffic lanes have been moved over slightly to the north to avoid construction works.

A section of the central median strip will be temporarily removed to allow this shifting over of traffic.

A traffic management plan is in place with barriers and signage.

Access to retail outlets

There will continue to be access to the retail outlets at 8–14 Quay Street, with slightly altered areas for entry and exits clearly marked.

Working hours on the project

Working hours on the site are from 7.30am to 6pm Monday to Saturday.

Occasional work outside these hours may be required, but we will notify affected residents if this is necessary.

Noise and truck movements will be kept within acceptable limits.

Tree removal and replanting

Two pōhutukawa trees on the roadside along the triangle of grass at 16 Quay Street have been carefully removed and will be looked after for the duration of the project.

After the project finishes, they will be replanted as close to possible to their original positions.
