Remedial and safety improvements 2022–2024

Work is underway to bring the Ngāruawāhia section up to the same standard as its neighbouring 110km/h sections.

On-going work includes:

  • Reshaping and hardening the median area – to limit moisture entering the pavement and prevent further failures.
  • Drainage improvements.
  • Resurfacing, depending on the existing pavement condition.

A final, continuous asphalt surface will complete the repair works, replacing the temporary chipseal and asphalt surfaces which have been in place during earlier temporary repairs and while moisture monitoring was conducted.

The safety improvements needed to get to 110km/h standard include making side barriers continuous, upgrading some barriers, additional maintenance and turnaround bays for emergency services, shoulder widening and relocating some lighting.

The works are expected to finish in mid-2025 although the Transport Agency and its contractors are continuing to look at programming and resources to finish the job earlier.
