The massive clean-up of forestry debris that flooded a small town north of Gisborne has begun.
Heavy rain on Monday caused water to flood through homes in Tolaga Bay, made worse when the Mangaheia River burst its banks.
This morning, Tairawhiti Civil Defence Emergency Management staff will fly to isolated properties to provide welfare checks and essential food supplies.
"We are still assessing the full extent of the damage but the preliminary costs are estimated to be around the $10 million mark," said Christine Boyce, Gisborne District Council communications manager.
"The clean-up will take several months."
