The Whangārei District Council said on Tuesday the Ngunguru River was "very high". The river later flooded across the main road out to the Tutukākā Coast.
Scows Landing was almost completely waterlogged making passing through a massive challenge for motorists.
The council also reported flooding at Punaruku and Russell Rd.
Last night motorists around Northland became stuck in deep water on several roads due to flood waters.
