Prosser Street watermain renewal
On behalf of Porirua City Council we are renewing an aging drinking water pipe in Prosser Street as part of our long-term programme of work to upgrade the city's drinking water network.

Latest Updates
By the end of February 2024, the team has installed over 850m of pipe.
We are about to start on stages 2 and 3 of the watermain renewal.
Construction commences 26 June 2023 and will be completed over the following 12 months in four stages to minimise traffic disruption - as shown below.
Hours of work will be 7am-5pm Monday to Friday.
- Stage 1 – Titahi Bay Road to Heriot Drive. Eastbound traffic will be diverted along Heriot Drive.
- Stage 2 – Heriot Drive to Raiha Street. Traffic will be under contraflow through this section.
- Stage 3 – Raiha Street Roundabout. Eastbound traffic will be diverted around Mohuia Crescent.
- Stage 4 – Northern 180 PE Pipe Construction – Footpath and parking will be closed.
- Stage 5 – Southern 180 PE Pipe Construction – Traffic will be under contraflow.
The pipe along Prosser Street is aging and has a history of failures.
We are replacing it with a new pipe as well as carrying out some realignment at 2 Prosser Street.
This work will improve the resilience of the local network and ensure a more reliable service.
The works will require traffic restrictions and at times, parking and footpath closures. To minimise impacts we are doing the works in stages and traffic management will be in place as follows:
- Stage 1 – Titahi Bay Road to Heriot Drive. Eastbound traffic will be diverted along Heriot Drive.
- Stage 2 – Heriot Drive to Raiha Street. Traffic will be under contraflow through this section.
- Stage 3 – Raiha Street Roundabout. Eastbound traffic will be diverted around Mohuia Crescent.
- Stage 4 – Northern 180 PE Pipe Construction – Footpath and parking will be closed.
- Stage 5 – Southern 180 PE Pipe Construction – Traffic will be under contraflow.

Prosser Street renewals
Here's the extent of the works shown in red:
And as detailed below, the works will involve some traffic disruptions:
- Stage 2 – Heriot Drive to Raiha Street. Traffic will be under ‘contraflow’ through this section, meaning traffic travelling in both directions will use one side of the road while the other side is being worked on.
- Stage 3 – Raiha Street Roundabout. Eastbound traffic will be diverted around Mohuia Crescent.
During the work, we will be crossing the intersection between Mohuia Crescent and Prosser Street. To carry out the work safely and to minimise disruption, we will close one side of the intersection at a time. Two-way traffic will be possible; however, businesses may prefer to enter and exit Mohuia at the Raiha street roundabout.
Once we have completed work to the roundabout at Raiha Street, we will return to Stage 1: Titahi Bay Road to Heriot Drive. Eastbound traffic will be diverted along Heriot Drive.
Other stages of the project are:
- Stage 4 – Northern 180 PE Pipe Construction – Footpath and parking will be closed.
- Stage 5 – Southern 180 PE Pipe Construction – Traffic will be under contraflow.
We understand this work is disruptive and appreciate your understanding as we work to improve Porirua city’s infrastructure..
