State Highway 33 remained closed from Paengaroa to Okere Falls overnight due to several slips and fallen debris.
Waka Kotahi NZ Transport Agency said at 8.15pm Sunday the road would stay closed overnight due to multiple weather events and asked motorists to avoid the area.
State Highway 2 was now open under stop/go traffic management at the Kaikokopu Bridge at Pukehina. Delays are expected. It was previously closed because of a 100-metre stretch of flooding.
"We anticipate the flood water is at its highest now – but if the water rises we will have to fully close the road again," a Waka Kotahi media statement said.
