Each summer, NZTA carries out a road renewal programme to keep Manawatū-Whanganui state highways 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. This programme is in addition to our regular state highway network maintenance.
In our region, roadworkers maintain sections of SH1, SH2, SH3, SH4, SH54, SH56 and SH57.
Our teams maintain and manage the state highways from north of Raetihi on SH4 and north of Taihape on SH1 all the way to Levin on SH57 and SH1 and Eketāhuna on SH2.
We prioritise road safety, reducing disruption and minimising future costs by targeting areas with the greatest needs, focusing on the high-risk areas and those with high traffic volumes.
Most maintenance work happens during the spring and summer months when there is reduced rain and warmer weather. The warmer temperatures and dry air helps new seal stick to the road and ensures the durability and quality of the finished product.
We are confirming the renewal sites for this summer’s renewal programme. Some confirmed sites are included in the table below and we will publish a full list of the sites here once they are confirmed.

Winter may bring colder, wetter conditions, but our maintenance teams stay busy keeping state highways safe. While road resealing isn’t suitable in winter, essential work continues, including drain clearing, vegetation control, and pothole repairs. Potholes can occur year-round but are more common in wet weather. Roadworkers respond to issues as they arise, especially after heavy rain.
Winter can be tough on our roads, and unexpected closures from flooding or slips can occur. Roadworkers often work in challenging conditions to restore access and make roads safe as quickly as possible. With shorter days, more work happens at night, where lower visibility makes it harder to see road crews—please stay alert and follow traffic signs to help keep everyone safe.
Although major road rebuilds, resurfacing and resealing happens in warmer months, planning for the next season begins well in advance. Throughout winter, our teams assess highways, checking road surfaces, drainage, and assets, including bridges, signs, and streetlights. This helps prioritise summer work where it’s needed most, minimising future disruptions.
