Ōkahu Bay outfall diversion project

We are making improvements to the stormwater network to make Ōkahu Bay safer and reduce the flood risk for Watene Crescent and Tāmaki Drive.

​When the works will take place

The works are expected to start in August 2023. We expect to complete them by mid-to-late December 2023.

What the new stormwater outfall and pipeline will do

Following heavy rain, a one-metre hole has formed on Ōkahu Bay Beach, next to the existing stormwater outfall (see ‘existing outfall’ on the map).

This poses a health and safety risk to beach users.

To address this, we will relocate the stormwater outfall to Tāmaki Drive (see ‘proposed outfall’ on the map).

We will also upgrade the stormwater pipe crossing Tāmaki Drive to increase the network capacity and reduce the frequency of flooding on Tāmaki Drive.

While most of the work will take place along the beach, there will be work required on Tāmaki Drive near the intersection with Ōkahu Street. You can see the proposed pipeline in blue on the map.

As part of the work, Vector will install cables across Ōkahu Street and Tāmaki Drive.

​How this project will impact you

The works will take place from Monday to Friday between 7.30am and 6pm.

Traffic management plan

A traffic management plan approved by Auckland Transport will be in place for the duration of the works. This will ensure the health and safety of road users and pedestrians.

Tamaki Drive is expected to stay open for the duration of the works. However, the alignment of traffic lanes will be altered.

This will be clearly signposted with traffic management in place.

Street parking

Ōkahu Street will remain open while Vector installs the cable. Street parking will not be available while the installation takes place.

How long the works will take

This work is expected to take around five months.

Bus stops

The bus stop of the south-side of Tāmaki Drive (for city-bound buses), will be relocated for the duration of the project. It will move 100 metres east towards Watene Crescent.


We will post signage at the entrances to the beach to ensure the health and safety of beach users.

Access to properties

Access to properties will be maintained and businesses can remain open.

Footpath access

Footpaths will remain accessible with any closures and diversions clearly signposted.

Noise, vibrations and dust

There may be some construction noise, vibration, and dust while we work. We will monitor these to ensure they remain within permitted limits.
