People are being urged to slow down on the roads as roading contractors to clean-up following recent heavy rain.

People using roads in affected areas are being asked to adjust their driving to the conditions, which means slowing down, increasing following distances, switching headlights on and watching for flooding and other debris on the road.

"As heavy rainfall watches remain in place for parts of Bay of Plenty, northern Tairāwhiti, Coromandel, Tasman and Fiordland, possible slips and flooding will disrupt travel in affected regions, making some roads impassable and others likely to close at short notice," says a Waka Kotahi NZ Transport Agency spokesperson.

"Please avoid unnecessary travel in these areas if possible.

"We want to thank road users for their continued patience and all our roading contractors for their hard mahi/work."
