Walking and drivingOverview
We want to make it easier and safer for you to use the intersection of Marne Road and Onslow Road in Papakura.
The proposed roundabout will help slow vehicles and make it clearer and safer for people to move through the intersection whether you're walking, cycling or driving.
We're planning to install a new fully mountable roundabout to slow traffic and support safer crossing and turning from Onslow Road.
As part of this we plan to:
- add 4 new pedestrian crossings:
- 3 refuge crossings on Onslow Road West and Marne Road
- 1 raised zebra crossing on Onslow Road East - this will only be built if the ground conditions are suitable
- install new widened footpaths, realign kerbs and berms
- add new road markings and signs
- improve street lighting so the crossings and roundabout are easier to see, especially at night
- install new broken yellow lines (no stopping at all times) to keep parked vehicles clear of the crossings and improve visibility for pedestrians and drivers.
As a result of these changes, 24 on-street parking spaces will be removed on Marne Road and 11 on-street parking spaces will be removed on Onslow Road.
Latest updates
To make space for the changes we propose, we'll need to remove 24 on-street parking spaces from Marne Road and 11 on-street parking spaces on Onslow Road.

Project background
We are working to make it easier and safer for you to use the intersection of Marne Road and Onslow Road in Papakura, whether you are living nearby, working or visiting the area.
This intersection has been identified as a safety concern for the community.
Between 2020 and 2024, 10 crashes were reported, including four minor-injury crashes.
- Most involved drivers crossing or turning from Onslow Road and not giving way to traffic on Marne Road.
- 1 crash involved a person cycling.
- 2 involved people crossing Marne Road.
Our investigation found that the main issues were drivers choosing unsafe gaps in traffic and the lack of suitable pedestrian crossing facilities.
These improvements are intended to reduce crash risk and create a safer, more accessible and better-connected area for everyone who uses this intersection.
