MetService has issued heavy rain warnings for much of the top half of the country today including Northland, the Coromandel Peninsula, Gisborne - north of Tolaga Bay - and the eastern ranges of Bay of Plenty.
People in those areas are being warned that heavy rain could lead to streams and rivers rising rapidly.
"Surface flooding and slips are also possible and driving conditions may be hazardous," MetService said.
Stacey Lee Clarke, a Hikuai resident, posted on the Coromandel Peninsula Road Status Facebook group saying "water is coming in fast with high tide not until a bit later".
Another poster, Sandra Morris, described Hikuai as being "underwater" as a result of the heavy rain.
On the Cooks Beach Community Facebook group, Penny Yates posted images of a boat being grounded at the beach.
"Sad to see this on front beach presumably from Flax Mill Bay," she said. "Looks like the anchor rope is snapped."
Motorists in parts of the North Island are being warned to drive carefully after heavy rain and wind downed trees and caused slips.
It comes as a deep low and associated fronts are expected to move south over the upper North Island during today.
MetService said the system was forecast to bring rain and strong east to northeast winds to much of northern New Zealand.
In the Coromandel-Thames district, there are slips and debris on Kopu-Hikuai and Tairua-Whitianga roads. Contractors are working to clear the damage.
High tide is expected at 3pm which could lead to further surface flooding.
In Waikato, a large tree had fallen on Manaia Road along State Highway 25, blocking both lanes of the highway. The road is closed and drivers are being asked to avoid the area.
MetService's heavy rain warning is in place until 6pm, and rain continues to fall across most of the North Island.
Whangarei had received the most rain in the past 24 hours, MetService said, reaching 87mm.
Meanwhile, there are strong winds Auckland, Coromandel, Bay of Plenty, Waikato, Rotorua and Gisborne.
White Island recorded 137km/h gusts overnight, and Tiritiri Lighthouse in Auckland saw 109km/h, MetService said.
Despite more than 20 milimetres of rainfall overnight in parts of drought-stricken Northland, farmers say it is still not enough.
Northland Federated Farmers president John Blackwell said some areas had more rain which was long overdue but overall it would only make a slight difference.
The rain had come too late and the grass was the shortest it had been, which meant the financial impact would be felt for years to come, he said.
