Auckland System Management (ASM) is an alliance between NZ Transport Agency Waka Kotahi, Fulton Hogan and HEB Construction. We maintain and manage Auckland’s state highway network:
If you’re unsure if the state highway in your area is maintained by Auckland System Management, please email us at info@asm.nzta.govt.nz
To keep Auckland’s state highway network safe, reliable and tidy we carry out regular maintenance and renewal activities including:
Email alerts are a safer, greener way to keep our customers updated on Auckland state highway maintenance that has been scheduled in their neighbourhood. We send out email alerts for maintenance activities that may be noisy or disruptive.
The safety and wellbeing of our team is important as we want everyone to get home safely to their families at the end of every day.
Hand delivering work notifications along some parts of the network puts the safety of our team at risk. Emailing work notifications helps to reduce the risk, while also providing a more responsive and environmentally friendly way to communicate.
Using email alerts means we can also notify the wider community, not just those who live next door to the network.
If you’d like to be notified of work in your area, we encourage you to sign up for email alerts.

We also use electronic signage (VMS boards) along our network to keep road users informed of estimated journey times, incidents along our network and closures that may have a significant impact to your travel.
For safety and environmental reasons, we no longer deliver letters to people living near the motorway every time we carry out maintenance.
We try our best to keep to the dates we have published, but sometimes maintenance needs to be rescheduled or cancelled due to weather, unforeseen circumstances or COVID compliance requirements. Please check the Waka Kotahi Journey Planner for the latest updates in your area before starting your journey.

ASM usually carries out scheduled maintenance works between Sunday and Thursday from 9pm to 5am. This is when traffic volumes are at their lowest so we reduce disruption to road users and keep our road crew and road users safe.
During a semi closure traffic will still be able to travel in both directions along the state highway. There are several ways we manage a semi closure:
During a full closure all lanes in one direction will be closed and traffic will be directed along an approved detour route.
We believe every road worker should go home safely. In some instances, a full closure is necessary to allow our teams to carry out work in a safe and uninterrupted environment. It also means we can get more done in so there are fewer future disruptions in your area throughout the year.
If your vehicle can’t use detour routes, contact us at TMC@asm.nzta.govt.nz
For oversized vehicle we need the following information:
Because we can only let vehicles through at scheduled times, there may be delays to your journey.
We want to reduce the number of visits to your area, and to do this effectively we use full closures to carry out more maintenance in one visit, giving our teams a safe and uninterrupted working environment. However, this will mean longer detour routes.
For details of closures in your area so you can plan ahead:
Regular maintenance is essential to keeping our network safe, reliable and tidy and we appreciate your support.
Sometimes we need to close on- and off-ramps so our team can carry out work safely and quickly. If there is a ramp closure a signposted detour will be in place.
The safety of road users and our road crews is our top priority.
Even when there is no one on site working, we may leave temporary speed limits, signs and cones in place to protect road users. When motorists disregard traffic management, they put their safety, that of other road users and our road workers at risk.
Thank you for your support during this time.
