What type of maintenance does ASM do?

To keep Auckland’s state highway network safe, reliable and tidy we carry out regular maintenance and renewal activities including:

  • Graffiti removal and recoating.
  • Vegetation control including mowing, weed and pest plant removal, tree trimming and felling, spraying.
  • Litter removal.
  • Resurfacing and rehabilitation, patching shoulder maintenance and special surfacing works.
  • Barrier repair and replacement.
  • Bridge inspections and repairs.
  • Lighting maintenance and replacement.
  • Installation of new gantry and ground-mounted signs.
  • Transport technology including cameras, variable message signs, loop detectors and signals.
  • Stormwater management.
  • Inspections.

What are email alerts?

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.

Why are we moving to email alerts?

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.

We are also committed to making positive changes for the environment.  We can remove the carbon footprint that creating, printing, and distributing over 1,000 letters every week creates.

How can I receive notifications about maintenance in my area?

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.

Will you notify me if work dates or times change?

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.

When do you carry out work?

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.

What’s the difference between a semi closure and full closure?

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:

  • lane restriction
  • stop/go traffic management
  • two-way traffic system using alternative lanes under traffic management supervision.

During a full closure all lanes in one direction will be closed and traffic will be directed along an approved detour route. 

Why do you use full closures?

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.

What if my vehicle can’t use the detour routes?

If your vehicle can’t use detour routes, contact us at TMC@asm.nzta.govt.nz

For oversized vehicle we need the following information:

  • OD load operator or pilot driver contact details.
  • Routes they are intending to travel so if any closures are affecting their travel journey, then we can provide details of STMS, and we will pass the OD operator details to the STMS or project sites so they can prepare well in advance for the OD arrival.
  • Size/dimension of the OD or vehicle.

Because we can only let vehicles through at scheduled times, there may be delays to your journey.

Why are there more full closures and longer detour routes?

We want to reduce the number of visits to your area, so we’re trialling a three-monthly maintenance schedule (excludes emergency work).

The new schedule extends the length of our full closures so we can 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.

Ramp closures – how will I get on and off the motorway?

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.

I don’t see anyone working. What’s going on?

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.
