Motorists are advised to drive with extra care and attention this weekend as heavy rain has led to an increase in slips and flooding in the region.
The New Zealand Transport Agency has issued a warning around State Highway 30 near Rotorua, State Highway 2 Matata Straights, Waimana Gorge, and Waioeka Gorge and State Highway 35 north of Opotiki.
Motorists should expect short delays on State Highway 5 at Tumunui as the road is down to one lane and speed restrictions are in place.
Engineers are closely monitoring two cracks which have appeared in the highway with geotechnical investigations being carried out to determine the cause of the damage.
Contractors will also be making safety improvements to the State Highway network around Rotorua and Opotiki over the next fortnight.
