Information about planned maintenance work to ensure the safety and resilience of the state highway network in the Waikato region.

Maintaining your roads

The 2022/23 road maintenance season will see more than $130 million spent across approximately 4000 lane kilometres of state highway in the Waikato.

Over 450 lane kilometres will be resealed or rebuilt over the summer period, starting in early October. This is our most significant programme of work in the Waikato region, and is part of a national programme focused on improving the condition of the state highway network.

Some of the region's most significant work sites this season included road resurfacing on several sections of SH1C in Hamilton, 20 lane kilometres of resealing on SH25 across the Coromandel Peninsula and 30 lane kilometres of work on the Desert Road. .

Given the volume of roadworks taking place this year, we acknowledge that at times there will be considerable disruption to travel across the region. Before leaving for your destination check the Journey Planner for the most up to date information on the state highway network.
