Access Kenepuru - improving Kenepuru corridor and surrounding streets

We're improving Kenepuru Drive and its connecting roads to make it easier and safer for vehicles, pedestrians and cyclists to travel to and from the city centre, and to public transport.

Kenepuru Corridor

Improving Kenepuru corridor and surrounding streets

Porirua City is growing, and we’re doing a lot of work to manage the increased traffic following the opening of Transmission Gully, other growth in the area and existing trip generators like Kenepuru Hospital and commercial businesses. Access Kenepuru encompasses a suite of improvements we would like to implement over the next few years. On this page you can find what's planned, what’s underway and what’s already been completed.

Raiha St / Kenepuru Drive intersection upgrade

Work is progressing well on the permanent roundabout at the Raiha St / Kenepuru Drive intersection.

Over the past couple of weeks, we have finished pouring the concrete for all the new paths and installed the new street lighting around the project. Night work has progressed well although Wellington Water is trying to trace a major watermain leak that we reported. As long as that leak is detected and fixed quickly, we plan to complete the base layer of the road this week.

Over the next fortnight, we will be installing raised traffic islands, asphalting the final road surface and starting on the landscaping work.

We are currently on track to complete work by early July.

The photo shows night works this week on the base layer of the road.

Raiha St / Kenepuru Drive intersection upgrade

Work continues to progress well on the permanent roundabout at the Raiha St / Kenepuru Drive intersection.

Over the past couple of weeks we have installed (and turned on) the new streetlights on the Kenepuru Hospital corner and Kenepuru Drive sections of the roundabout. We have finished the footpath on the business side of Kenepuru Drive. We began work on the final corner of the roundabout (left-hand side of Raiha St) where we have removed the streetlight poles, prepped the shared path and poured the new kerb and channel.

Coming up we will be pouring the shared path on the left-hand side of Raiha St. From Monday 27 May we begin night work to mill and pave the road surface around the roundabout. The work will take about five days and will be done in sections at night. There will be stop/go traffic management in place while the crew is operating. With work happening at night there will be minimal activity on site during the day, but traffic management will remain in place.

The photo below shows the newly installed and operating streetlights on the business side of Kenepuru Drive.


Work completed and planned

Work continues to progress well on the permanent roundabout at the Raiha St / Kenepuru Drive intersection.

Over the past couple of weeks we have been working on the business side of Kenepuru Drive. We have installed new drainage and constructed the new kerb and channel. Concrete has been poured this week for the new footpath and temporary asphalt laid on a portion of the carriageway.

Next week we will be installing the new streetlights on the Kenepuru Hospital corner and Kenepuru Drive sections of the roundabout – all going well we should be able to reconnect and turn these on next week as well. Once the streetlights are moved on the business side of Kenepuru Drive the final sections of the footpath can be completed. We will provide a temporary surface for pedestrians and cyclists until this work is complete.

Next week we also begin work on the final (southern) corner of the roundabout – this will involve excavating for the shared path and constructing the new kerb and channel.


Raiha St / Kenepuru Drive intersection upgrade

Over the past couple of weeks, work has progressed well on the Kenepuru Hospital corner of Raiha St and Kenepuru Drive. We’ve constructed all the kerb and channel, concreted the shared path in this section, and removed the streetlight poles on this corner. We are preparing the berm for topsoil and grassing, and we’re adjusting the temporary line markings on Raiha St back to the previous alignment. Once the new streetlight poles arrive, we’ll be installing and reconnecting these in early May.

Over the next couple of weeks, we'll be working on the next section on the business side of Kenepuru Drive. Work will include locating underground services, installing drainage, and starting construction of the new kerb and channel and shared path.

Please note: During these works, pedestrian on Kenepuru Drive will need to use the crossing on Raiha St. To make sure the crossing point is safe we will be providing a temporary pedestrian refuge on Raiha St.


Raiha St / Kenepuru Drive intersection upgrade

Here’s a brief update on progress to replace the temporary roundabout with permanent features at the Raiha St / Kenepuru Drive intersection.

Over the past couple of weeks, we’ve excavated and prepped the new kerb and channel on the Hospital corner of Raiha St and Kenepuru Drive. We’ve also started removing the streetlight poles on this corner. There will be a period of up to 6-8 weeks where lighting on this corner won’t be operational.

Over the next couple of weeks, weather permitting, we will be pouring the concrete kerb and channel, and constructing the shared path on the same corner. We plan to move to the next section of work, on the business side of Kenepuru Drive, from about 22 April.


Work to replace the temporary roundabout with permanent features at the Raiha St / Kenepuru Drive intersection is going well.

So far, we’ve been working at night but from Monday 25 March we’ll mostly be working during the day.

Over the past couple of weeks, we have focused on constructing the new roundabout. This has included all the preparation work and completion of the new central island, mountable kerb and concrete apron around the roundabout.

We have also removed the pedestrian refuge on Raiha St to allow for two lanes of traffic approaching the roundabout. A temporary refuge will be created during the work and a permanent pedestrian refuge will be installed later as part of the final design.

Over the next few weeks, weather permitting, we will be excavating the shared path on Raiha St (Kenepuru Hospital side) and replacing the kerb and channel.

Street lighting

Next week we will begin relocating the streetlights on the hospital side of Raiha St. These light poles need to be disconnected, moved out of the footprint of the new shared path and then reconnected. There will be a period of up to 6-8 weeks where lighting on this corner won’t be operational.

Please note there will be no work on the site over Easter Weekend.

Raiha Street / Kenepuru Drive intersection upgrade underway

We're replacing the temporary roundabout at the Raiha Street / Kenepuru Drive intersection with permanent features.

Overnight works started last week, and we're planning to start day works later in the month.

This week we removed part of the temporary traffic islands and signage, deconstructed the temporary roundabout, and started work on the new roundabout.

Next week, weather permitting, we'll be pouring the concrete for the kerbs and the permanent roundabout.

Later this month we'll be starting to work during the day on the hospital side of the roundabout.

Possible deferral of some Access Kenepuru projects

Like many Council projects, the Access Kenepuru programme of work is being reviewed as Council looks to manage rates rises in the next Long-Term Plan (LTP) period, 2024-34 (see here for the media release).

This affects our individual projects in different ways with some subject to deferral. Unfortunately, we won’t know for sure until late June 2024 what the confirmed budget phasing for the next stages of our projects will be (i.e. after public consultation on the LTP).

What this means for our four projects:

  • Raiha/Kenepuru intersection: construction to go ahead as planned in 2024.
  • Te Ara Tawa and Ferry Place paths project: this project is currently under review and whilst the current design phase will be completed this year construction is expected to be deferred until at least 2027/28.
  • Kenepuru Drive intersections with Lyttelton Ave, Lower Main Drive and Titahi Bay Road: complete design phase with construction proposed to be deferred until 2025/26 and 2026/27.
  • Raiha Street / Prosser Street corridor study: the upcoming design stage is proposed to be deferred until 2028/29.

May 2023 - Lower Main Drive accessway

We’re receiving great feedback following the opening of the new accessway on Lower Main Drive for Bishop Viard College, the Seventh-day Adventist Church and Te Ngākau Tapu Parish. We’ve also finished construction of a new carpark for the Seventh-Day Adventist Church.

This work was required because the existing accessways for the college, church and parish off Kenepuru Drive needed to be closed to enable future upgrades to the Kenepuru Drive intersections with Lower Main Drive / Lyttelton Ave and Titahi Bay Road. These intersection upgrades are currently in the planning and design stage.



Raiha Street / Kenepuru Drive roundabout

Raiha Street / Kenepuru Drive roundabout

Work started in early March 2024 to replace the temporary roundabout at the Raiha Street / Kenepuru Drive intersection with permanent features.

The temporary roundabout took the place of a T-junction and was installed in December 2020 as a trial, ahead of the completion of Transmission Gully and its connection to Kenepuru Drive.

At the time there was a high level of uncertainty about the impacts from Transmission Gully and we wanted to see if a roundabout was the right way to go with a view to making this a permanent feature if we could realise the expected safety and efficiency benefits.

Benefits of the roundabout

Since the roundabout has been in place, we are seeing fewer crashes and better traffic flows. Prior to the roundabout we had 19 crashes (2015-2020) (12 non-injury and 7 minor crashes). Since installation of the roundabout in late 2020 our data shows 4 non-injury crashes (up to May 2023).

Buses and trucks can now make turns smoothly, vehicles speeds have slowed and there is better access for cyclists and pedestrians to cross the intersection more easily and safely.

We have reviewed and monitored the temporary roundabout and have taken in the lessons and made further improvements into the permanent design.

Features of the new roundabout

  • Tactile surfaces at crossing points to help those who are visually impaired.
  • 75mm high raised table to slow traffic, make it safer for pedestrians and to allow heavy vehicle to easily cross.
  • Reduced central island with mountable apron to improve large vehicle manoeuvring.
  • Reduced raised median islands to improve vehicle movements.
  • Green surfacing to show cycle areas and exit/entry points.
  • Designated cycle facility on Kenepuru Drive with raised separators.
  • Shared path on the Raiha St side of Kenepuru Drive extending up Raiha St.
  • Improved lighting.

Check out the roundabout design for more information.

Construction information

Work started in early March 2024 and is planned for completion by the end of winter 2024.

We are aware this is a very busy intersection. To minimise disruption as much as possible this work will be undertaken during the day and at night, with the more disruptive work scheduled to happen overnight.

What to expect

Daytime work - 7am to 6pm Monday to Saturday.

  • This work will include constructing the shared path, street lighting and landscaping.
  • Traffic management measures in place will include lane closures during off-peak hours and pedestrian diversions.
    • 7am-9am work will take place off the road, on the berms behind the kerb lines, to minimise disruption.
    • 9am-3pm any work that impacts/closes traffic lanes will happen during these hours which are off-peak. There may be some minor adjustments to these hours once we see the impact of this work on traffic.
    • 3pm-6pm work will take place off the road, on the berms behind the kerb lines, to minimise disruption.

Night time work - 7pm to 6am Sunday to Thursday.

  • This work will include roundabout construction and work on the road surface.
  • Stop/go, speed restrictions and other traffic management measures will be in place.
  • Access through the roundabout will be maintained.

Please use alternative routes where possible.

Te Ara Tawa and Ferry Place shared paths plus Lyttelton Ave / Walton Leigh Ave intersection upgrade

This project is currently under review. When it goes ahead, and subject to the funding available, we’d like to provide an improved, flat, safe and easy to use direct link for pedestrians and cyclists from Kenepuru Drive to the city centre and to public transport via Lyttelton Avenue. We’d also like to strengthen the east/west connection across Lyttelton Avenue and Walton Leigh Avenue so people can easily get from the city centre to Te Ara Tawa and to public transport options such as the train station and buses.

At the same time as we are looking to widen footpaths, we're also looking at measures to slow traffic down and encourage large heavy vehicles to use alternative routes as well as modifying Walton Leigh roundabout; all to increase pedestrian and cycling safety.

Why are we doing this?

Currently there is a lack of easy, safe, pedestrian and cyclist access between Kenepuru Landing and the city centre. The current Lyttelton Avenue footpath is narrow and interrupted by multiple laybys.

The best route to enter Te Manawa, the heart of the city centre, is from Lower Main Drive, across Kenepuru Drive and along Lyttelton Avenue to Ferry Place. The roundabout at the Lyttelton Avenue / Walton Leigh Avenue intersection currently does not make this easy for pedestrians with no direct surface crossing points.

An option for how these shared paths could look and how the intersection could be improved was available at public drop-in sessions in July 2021. Since then, the concepts continue to be refined.

Project timeframe

This project is being reviewed as Council looks to manage rates rises in the next LTP period, 2024-34. The construction phase of this project is likely to be deferred until at least 2027/28.

Kenepuru Drive intersections with Lyttelton Ave, Lower Main Drive and Titahi Bay Road

Improvements at all three intersections will make it easier and safer for pedestrians, and cyclists to get to and from the city centre and will keep traffic moving safely and efficiently. This is going to be especially important over the coming years as growth is expected to continue.

Why are we proposing these changes?

These intersections and side roads are already very busy and significant growth in the area is seeing more people walking and cycling which in turn puts increasing demand on existing crossing points. This growth, as well as changes in traffic patterns and volumes along Kenepuru Drive, including the impact of Transmission Gully, is causing further delays for motorists and safety concerns for all road users wishing to cross Kenepuru Drive. This is predicted to get worse as growth continues.

Development of Kenepuru Landing and Summerset on the Landing means the Lower Main Drive / Kenepuru Drive intersection needs upgrading to provide safe access for residents, now and in the future. These improvements will also give residents an alternative access to Bluff Road and Hospital Drive and will enable public transport to service Kenepuru Landing and Summerset on the Landing.

Any work to improve the Kenepuru Drive intersections at Lower Main Drive and Lyttelton Ave will impact on the Titahi Bay Road roundabout and vice versa hence why they are being investigated collectively.

Project timeframe

We are currently reviewing concepts for Lower Main Drive and Lyttelton Ave intersections, looking at improvement options for Titahi Bay Road roundabout and assessing how they would all work together.

This project is being reviewed as Council looks to manage rates rises in the next (LTP period, 2024-34 which could result in the next phases of this project being deferred until 2025/26 and 2026/27.

Raiha Street / Prosser Street corridor study

The Raiha Street to Prosser Street corridor is a busy part of the network with over 11,000 vehicle movements daily.

This corridor study has completed the early scoping stages to identify key issues and opportunities to improve safety and accessibility in this area and is now beginning to consider conceptual options for improvement.

Project timeframe

This project is being reviewed as Council looks to manage rates rises in the next LTP period, 2024-34 which could result in the design stage being deferred until 2028/29.

Completed projects

This roundabout was completed in November 2021 and provides a safe turning and crossing point for motorists, pedestrians and cyclists.

This work was completed in two stages in late 2021 to construct a shared pathway in front of ESR between Bluff Road and Kenepuru Railway Station.

The access to Kenepuru Station has been transformed, with improved lighting, resurfacing, vegetation improvements around Porirua Stream, removal of trip hazards and the installation of art work.

Improvements to these intersections were completed in 2021 to manage the extra traffic volumes expected following the opening of Transmission Gully.

Work included:

    • Raiha Street/ Broken Hill Road: to reduce the wide conflict area and the risk for all road users. (June 2021) View the plan
    • Raiha Street/ Prosser Street: construction of a mountable roundabout to reduce speeds and near misses between vehicles. (May 2021) View the plan
    • Main Road/ Wall Place: widen the intersection to reduce the delays for exiting traffic. (June 2021)

A safe crossing point for north bound cyclists on Kenepuru Drive to access the Porirua Stream Pathway was completed in 2021.
