Construction of the roundabout, including Vector works, starts on 23 March 2026 and will take approximately 13 weeks depending on the weather and Vector work.

Vector works
Vector is installing a new 33kV underground power connection at the intersection.
We are taking a dig approach and are delivering Vector’s trench work at the same time, approximately 72m.
Progress for this stage is heavily dependent on what sort of ground conditions we encounter. This would include existing services and if we need to lower them or not to fit in the power connection.
It will depend on what we find once we open the road.

Vector’s work is on Selwyn Street and Arthur Street east. It involves digging down 1.5m under the road.
Traffic management remains the same from Stage 2.

Project background
This project is part of Auckland Transport's High-Risk Intersection programme, a safety improvement programme that prioritises safety interventions at high-risk intersections in Auckland.
Between 2018 and 2025, 34 crashes occurred at the intersection, resulting in 1 serious injury and 12 minor injuries, primarily due to turning or failure to give way. Contributing factors include poor visibility, high approach speeds, and inadequate pedestrian facilities that are misaligned with the desire lines to nearby shops and schools.
Public engagement for the project was held in August 2025.
After reviewing feedback the project would proceed with removing the speed cushion on Arthur Street approaches to minimise the risk of excess noise and vibration on the minor road corridors.
The work we're doing:
- Installing a mountable urban roundabout, including any associated signage and road markings.
- Installing speed cushions on all approaches and traffic islands to slow approaching traffic and improve vehicle deflection when entering the roundabout.
- Providing pedestrian crossings on all four legs of the intersection, including the removal of the existing pedestrian refuge islands on Selwyn Street near numbers 74 and 110.
- Installing 2 driver feedback signs on Selwyn Street, one outside number 68 and another outside number 83.
