Waikato State Highway maintenance programme – summer season

NZ Transport Agency Waka Kotahi (NZTA) is gearing up for a busy summer with significant renewal work scheduled across the Waikato to ensure the region's state highways are safe and accessible.

Road users will notice more crews and work sites – from now through to the end of March 2026.

We’re doing as much work as possible between now and mid-December to reduce the impact on people's journeys during the busy holiday season. To achieve this we’re also heavily reliant on the weather and other factors co-operating.

This year's maintenance programme aims to renew around 112 lane kilometres across the Waikato (excluding the Tīrau to Waiouru project), to give drivers safer, smoother journeys, and to keep our state highways in good condition.

We appreciate road users slowing down through our worksites, helping keep our crews safe as they work long hours, day and night, throughout summer, while others are out enjoying their road trips. Slowing down through work sites helps keep everyone safe. Road conditions may be unfamiliar or changing, so it’s important to stay alert and reduce your speed. Slow down. Be alert. Be safe.

How to be safe around roadworks

Our contractors carry out the maintenance work across Northland on behalf of NZTA, so you will likely see their crews when you’re out travelling through the region.

Kia Tupato Ki Nga Kaimahi – please watch out for any road workers. We care about our team and believe everyone has the right to return home to their whanau at the end of the day.

Always reduce your speed, adhere to the temporary speed limits and follow the traffic management directions at our work sites.

It’s important to slow down through newly sealed sections of road because small chips can be flicked up from the road surface and damage vehicles – especially windscreens. That’s why we often keep temporary speed limits in place even after it looks like the work has been completed. As well as safety, the temporary speed limit also helps ensure the quality of the reseal. Travelling at the posted temporary speed limit allows for the chips to be embedded into the road surface and for them to remain in place as the seal cures.

Please be patient with our crews as they set up and pack down work sites including placing or removing cones and signage. Overtaking these working vehicles can be dangerous to our teams on the trucks but also to vehicles travelling in the opposite direction.

If you have any concerns or require information about works in your area call 0800 4 HIGHWAYS (0800 444 449).
