Police say all roads around Thames and the Coromandel are now open, despite some slips as a result of Sunday's heavy rain.
The rain led to flooding in Whitianga and Tairua, and sudden high winds tore roof tiles from houses in Papamoa.
The rising water affected campsites, with families forced to leave their submerged tents and some choosing to go home.
As many as 10 families at the Otama Beach Camp had to be moved as flood waters 60 centimetres deep engulfed their tents.
Campground manager Claire Elliot says it could take days to fully dry out and some families are staying on.
