Manawatū-Whanganui region maintenance programme

The 2024-2025 summer renewal seasonBack to top

The 2024-2025 state highway road renewal season in the Manawatū-Whanganui region has wrapped up, with more than 110 lane kilometres* completed.

This summer maintenance season, roadworkers rebuilt 27 lane kms, resealed 88 lane kms and completed 4 lane kms of asphalt resurfacing.

This programme is in addition to our regular state highway network maintenance.

We scaled up our road rebuilds this year and increased the amount delivered compared to the previous year. Road rebuilds are a key priority and often involve removing the existing road surface and road layers and replacing them with new materials to improve the long-term condition and quality of the road.

The summer renewal season typically runs from October to March when the weather is warm and dry to ensure it is effective and long-lasting.

We appreciated the patience of all road users throughout Manawatū-Whanganui as we completed this necessary maintenance work on the region’s roads.

Road maintenance activities keep our roads safe, secure, and ensure reliable access for communities. We know that a well-maintained state highway network promotes safety and improves options for moving people and freight.

Even though the summer season is complete, you’ll continue to see our roadworkers carrying out maintenance this winter and working on other state highway projects.

*Lane kilometres are the total length of lanes to be resealed or rehabilitated. For example, resealing both lanes of a 10 kilometre stretch of two-lane highway results in 20 lane kilometres.

Speeding over a freshly sealed road can damage the new seal, lifting and flicking stones from the road that can, in turn, damage nearby vehicles or your own.

To minimise the risk of damage to both vehicles and the new seal, it is crucial that road users adhere to all temporary speed limits in place.
