The Whangarei District Council is urging motorists to take extreme care on the roads following predictions of more heavy rain.
Glenmore and Tongatu roads remain closed due to slips on Tuesday. Conditions are expected to become more treacherous over the next few days.
The council's infrastructure and services manager says contractors are working to remove debris and have erected warning signs in some areas.
Simon Weston warns damage to roads is so widespread and the conditions are such that even the most careful driver could get into trouble.
