Underground cable relocations
Cable works continue in Lower Hutt
Since mid-November 2025 major works have been underway in Lower Hutt as part of Te Wai Takamori o Te Awa Kairangi.
To make way for the new Melling Bridge, stop banks, and shared pathways, Wellington Electricity have been trenching key roads within the city centre to lay ducts to relocate underground electricity cables inside the construction zone.
The work needs to be done before major construction gets underway, to help avoid future disruption and keep the wider project on track.
Progress update and next steps
The ducting works are expected to be complete by 30 April 2026. Wellington Electricity will then begin digging a series of individual access pits (called joint bays) along the route, so that the news cables can be fed through them. The ducts needed to be in place before cable hauling could begin, and these jobs could not be performed at the same time.
The work is expected to be completed by August 2026.
Impacted roads: Connolly Street, Rutherford Street, Dudley Street, Andrews Avenue, Daly Street, Queens Street roundabout (southern end of the city), Marsden Street.
What to expect
The work will involve digging several large joint bays at selected locations along the route (see the map at the bottom of this page), before hauling the new electricity cables through them.
Crews will work on the joint bays in stages, and will move back and forth between the bays which are situated along the route as each stage is completed.
Here's how it will work
1. Excavate the pit down to the ducts and cut the ducts open.
2. Move on to open the next pit in the sequence and repeat.
3. Return to clean the ducts and haul the cables through.
4. Join the cables together once they’ve been hauled.
5. Fill in the joint bay and fully repair the footpath and road surfaces.
Because of this staged approach, there will be times when a joint bay has been opened and is not being actively worked on.
In these circumstances, an open joint bay left unattended will be securely closed off with site fencing and surrounded by traffic management until work can be completed and the site fully reinstated.
Weather and ground conditions permitting, it is likely that some joint bays could be open for up to six weeks.
Occasionally, there may be delays or work may need to be rescheduled due to other factors that can arise during underground excavation.
What you will see and hear
There may be some moderate noise from the equipment used, and Wellington Electricity will do their best to keep disruption to a minimum while fully complying with all noise regulations.
To carry out this work safely, they may need to set up temporary traffic management in your area, which will include temporary lane closures, stop/go vehicle management, and removal of parking on both sides of the road where work is taking place.
This traffic management will be in place 24/7 for the duration of the works, but are to expected have a reduced footprint than what was in place for the previous trenching work.
Indicative traffic management maps and up-to-date timelines for each joint bay site will be available here: www.welectricity.co.nz/major-projects/teawakairangi
Access to residences and businesses will be maintained, however in some cases this will need to be managed by the traffic management supervisor. If Wellington Electricity need to block your access to your driveway as part of the work, they will knock on your door the day before work begins.
To ensure your safety, please follow all signage and crew instructions while the work is underway, and make sure that children and animals are kept well clear of the area until completion.

Frequently Asked Questions – Cable Relocation Work
Why is this work happening?
Wellington Electricity is relocating underground power cables to make room for major improvements being delivered through Te Wai Takamori o Te Awa Kairangi. This includes flood protection, transport upgrades, a new Melling Interchange, shared pathways and a new pedestrian bridge.
What has been completed so far?
Between November 2025 and April 2026, crews have trenched along the route to install new underground ducts. These ducts will carry the electricity cables.
What factors have influenced the timeline for this work?
Once work began, crews encountered complex underground conditions and adverse weather which impacted progress on certain parts of the route.
What is happening now?
Wellington Electricity is digging a series of individual joint bays at intervals along the route. These joint bays enable the new cables to be hauled through the ducts installed earlier.
Where will the access pits be located?
Exact locations vary depending on cable alignment. A detailed map and schedule will be available as plans are finalised.
Visit: www.welectricity.co.nz/major-projects/teawakairangi
Will this stage be as disruptive as the trenching?
Disruption should be lower than during the trenching phase. However, some traffic management and lane changes will still be needed around individual joint bays for safety.
Will I still be able to access my home or business?
Yes. Access will be maintained wherever possible, and crews will work directly with property owners where special arrangements are needed.
What hours will crews be working?
Work will take place during the day, with any night work notified in advance. Timings may differ depending on the location and traffic conditions.
How long will this work take?
The duration varies by location and complexity. We will provide estimated timeframes when detailed plans for each section are released. Keep up to date via www.welectricity.co.nz/major-projects/teawakairangi
Will my power be turned off?
Most of the work can be completed without outages. If an outage is required, Wellington Electricity will notify affected customers directly with advance notice.
Who can I contact if I have questions or concerns?
