Wellington Water crews responding to a heavy rain event and surface flooding
Wellington Water crews responding to a heavy rain event and surface flooding

Wellington Water crews are actively responding to a band of heavy rain causing surface flooding and network impacts across the Wellington, Kāpiti Coast and South Wairarapa regions today.

Reports of flooding have been received this morning in Stokes Valley, Naenae, Upper Hutt, Plimmerton and Porirua areas. We currently have around 5 crews deployed across affected areas and working closely with local councils to respond as conditions evolve.

Heavy rainfall has led to surface flooding on key transport routes,please see NZTAs latest update for road closures.

Additional resourcing has been activated from across the region and are focusing on known flooding hotspots.

Crews are working as quickly as they can, but we are advising residents to bear with us as response times in some locations are being impacted by restricted road access.

Wellington Water is continuing to monitor conditions closely and will respond to all service requests as they arise.

We are keeping the public and impacted communities up to date via our website and social media channels. For further updates, please check the Wellington Water Facebook page: https://www.facebook.com/share/p/1Dgm5dd54q/

Latest Updates

15 January 2026 Works underway at Cockayne Road and Imlay Cresent

Works commenced at Cockayne Road and Imlay Crescent on Monday 12 January, with our contractors G P Friel Ltd excavating each end of the pipe to prepare it for cleaning.

6 January 2026 Works beginning at Cockayne Road and Imlay Crescent

A critical drinking water pipe running between Cockayne Road and Imlay Crescent was taken out of service following a burst in June 2024. 

 

Since then, water has been supplied to the northern part of Ngaio via the Mount Kaukau Reservoir. This is a temporary solution which is not sustainable for the network, especially during summer months. 

 

We are planning to repair the current pipe and re-line it with Cured In-Place Pipe Lining (CIPP) — a modern, low-impact method that lets us strengthen the pipe from the inside without digging it up.

15 January 2026 Works underway at Cockayne Road and Imlay Cresent

Works commenced at Cockayne Road and Imlay Crescent  on Monday 12 January, with our contractors G P Friel Ltd excavating each end of the pipe to prepare it for cleaning. Letters have been distributed to Cockayne Road and Imlay Crescent households regarding the works and traffic management, which will be in place for about two weeks.

Following the repair of the pipe we will pause works while we await delivery of the lining material, before the re-lining and curing process takes place from February to the end of April.

6 January 2026 Works beginning at Cockayne Road and Imlay Crescent

Wellington Water, on behalf of Wellington City Council, is renewing the drinking water pipe between Cockayne Road and Imlay Crescent which failed in June 2024. This pipe is a critical piece of the network which provides the water supply for northern Ngaio.

 

The first stage of this project will begin on Monday 12 January, and take about two weeks.  

 

For safety and to provide access for trucks and equipment, a section of Cockayne Road will be reduced to one lane, with a temporary 30km/h speed limit and stop-go system in place. Cars, buses, cyclists and pedestrians will be guided by traffic controllers past the work site. 

 

The end of Imlay Crescent will be closed to vehicles (except for those belonging to residents) and no roadside parking will be available. 

As the pipe is currently not in use, there will be no disruption to water services in the area due to these works. 

  • There will be some noise and vibration created by the works.

  • Working hours will be 7am to 5pm, Monday to Friday. Noisy plant and machinery will only be used after 7:30am. 

 

We understand this work could be disruptive and appreciate your understanding as we carry out this essential work. This project will support a reliable and resilient drinking water supply for the northern parts of Ngaio.
