Motorists are urged to take care on the roads and allow extra time when travelling this summer, with several maintenance and safety projects under way in the Bay of Plenty and Waikato.
The NZ Transport Agency's regional performance manager Karen Boyt said an extensive programme of reconstruction and resealing was planned between now and April.
"For most people, summer is a time to get outdoors, head to the beach and have fun but it's also a time when our contractors are busy repairing road surfaces and carrying out important safety improvements," she said.
Ms Boyt acknowledged that road works could be dusty, noisy and, at times, frustrating for drivers, but said the work ensured there were better and safer roads for everyone to travel on. "Summer is the best time to reseal our roads as warmer temperatures and dry air helps new seal stick to the road surface.
"Cold ground conditions, wet weather and moisture mean we cannot carry out this maintenance work during the winter months. We try to minimise the impacts of the work but people can expect short delays due to speed restrictions and stop/ go traffic control.
