The Ngā Ūranga ki Pito-One (Ngauranga to Petone) section of Te Ara Tupua will be built on the harbour’s edge from Ngauranga Interchange to Honiana Te Puni Reserve in Petone and connect with the new Pito-One to Melling section.
The project will create a new resilient coastal edge protecting the road and rail, and additionally provide a safe and attractive walking and cycling link between Wellington and Lower Hutt.’
It is being delivered in partnership with iwi mana whenua, Taranaki Whānui ki te Upoko o te Ika, and Ngati Toa Rangatira.
What’s happening?
Updated September 2024
Work is underway to connect the central zone at Karanga to Pito-One. The teams are gaining more ground every week with 40% of the interlocking concrete blocks required for the project, now in place. The construction teams will be focusing on building the vertical seawalls, rock revetment and ūranga (landings). The uranga will provide areas for gathering, resting and viewing for people to use. We’ll also be placing large rocks (pictured above) to cap the revetment as we finish in these areas.
Main construction areas 2023-2026
Honiana Te Puni Reserve
Construction work on Honiana Te Puni Reserve is now complete. For more information please visit the Honiana Te Puni Reserve page.
Background
Te Ara Tupua Alliance has been formed to design and construct the project.
The Alliance is a team made up of NZ Transport Agency Waka Kotahi and our design and construction partners Downer NZ, HEB Construction and Tonkin + Taylor.
NZ Transport Agency Waka Kotahi is partnering with Taranaki Whānui ki te Upoko o te Ika and Ngāti Toa Rangatira as iwi mana whenua, and our other partners include KiwiRail, Hutt City Council, Greater Wellington Regional Council and Wellington City Council.

Key elements
Key elements of the Ngā Ūranga to Pito-One section include:
- Revetments: 2.7km of sloping coastal defences protecting the shared path and ūranga. These are designed with the ability to adapt to sea-level rise and are 16m wide on average.\
- Seawalls: 6 seawall segments protecting the shared path, totalling approximately 600m in length. Seawalls are used where necessary to avoid high-value habitat areas.
- Offshore habitats: small offshore habitats for coastal bird life, constructed of naturalised rock forms.
- Shared Path: A 4.5km shared path with a 5m wide sealed surface on the seaward side of the Hutt Valley Railway Line
- Ūranga (landings): 6 ūranga (landings) located at key sites along the shared path’s length providing areas for planting, landscaping, habitat creation, and gathering, resting and viewing areas for people to use.
- Shared path bridge at Ngā Ūranga: A new architecturally designed bridge providing access over the railway.

More people walking and cycling
We want to make it possible for people to move around our region in more ways, and contribute to healthier communities. Right now, there is no safe walking and cycling route between Wellington and Lower Hutt.
By providing a safe, attractive path, away from vehicle traffic, Te Ara Tupua will make it possible for more people to change how they travel. More people walking, running, biking or scooting means lower emissions from transport and less pressure on our roads, buses and trains.
By 2030, we estimate people making over 2100 trips by bike on the path each weekday, as well as 360 walking or running trips and around 290 trips on e-scooters or similar devices.
Resilience to climate change
The coastline between Ngā Ūranga and Pito-One is a crucial infrastructure corridor with the road and rail, and critical cables and pipelines beneath the surface. Parts of this system have been damaged by severe weather in the past, like in 2013 when the rail line was washed out causing days of travel disruption/
Te Ara Tupua’s new resilient coastal edge (seawalls and embankments) will help protect the road and rail corridor from the damaging effects of storms.
As well as increased storms, climate change will also cause sea levels to rise. When we build this section of Te Ara Tupua, the embankments and seawalls will be future-proofed so they can be raised in future.
Emergency access
In the event of a disaster that blocks the road or rail lines, the path will be able to act as a recovery route between Wellington and Lower Hutt. It will be further out from the hills and cliffs, meaning it is less likely to be impacted by land slips that can be caused by heavy rain or by earthquakes.
During recovery from a disaster, or if there’s an emergency on the path, vehicles (like ambulances or fire trucks) will be able to use the path.
Environment
While the coastline between Ngā Ūranga and Pito-One has been built on in the past to create our road and rail links, it is home to many different species. Te Ara Tupua will be built in a respectful way that preserves as much of their habitat as possible while ensuring they can continue to live along the coast once the path is complete.
In most areas, the path will be supported by a man-made embankment known as a revetment.
Other parts of the coastline are made up of gravel beaches, which provide valuable habitat. In these areas we have designed a vertical seawall. The seawall has a much smaller footprint meaning almost all of the gravel beach areas will be preserved.
Ecological screens on top of these seawalls will reduce disturbance from people on the path to the birds and other species that use these areas.
Two offshore habitats that look like small islands are being built to provide a place for birds to roost.
