Waka Kotahi NZ Transport Agency is advising motorists in Tairāwhiti and further south in Hawke's Bay to take extra care and to "stay alert" as severe weather creates challenging driving conditions.
The downpours caused potholes to appear on the road, which crews were doing their best to address.
"Our contractors have been out in the rain over the last couple of days, working hard to ensure that the state highways remain safe for motorists," Waka Kotahi's regional maintenance and operations manager Jaclyn Hankin said in a statement.
"Potholes and debris have appeared on roads across the region, so please keep speeds down and stay alert. We want everyone to get to their destinations and back home safely.
"It will take some time for us to repair all the potholes, especially while the severe weather continues. Making permanent repairs to potholes requires warm, dry weather so until the rain clears we can only make temporary repairs.
"We need people to drive to the conditions for the safety of everyone on the roads, including our contractors who are doing a great job in very bad weather.
"If anyone sees any issues on the state highways, please call 0800 44 44 49 so that our contractors can get to the site quickly and fix the issue."
