New Zealand – Floods in Coromandel After 124mm of Rain in 24 Hours

Heavy rain fell in parts of the Coromandel Peninsula, New Zealand, over the weekend, causing floods and landslides in several areas including Colville.

New Zealand’s Met Service had issued warnings of heavy rain in Northland brought upon by a trough of low pressure moving southeast from the subtropics. As much as 124 mm of rain fell in 24 hours on 17 April in Whitianga. Some minor flooding was also reported in Auckland after steady rain throughout the day.

Thames Valley Civil defence warned yesterday:

“Heavy rain in the northern Coromandel has cut off some roads. If you are planning to travel north of Colville, please postpone your trip.”

Flooding was thought to have been worsened by the high tide in some costal areas. Several roads had disappeared under water. Landslides were reported in Kennedy Bay, Port Charles and Waikawau Bay. Road blockages left residents of Colville cut off for some time yesterday. At least 2 families had to evacuate their homes. Local emergency crews said they carried out 1 flood rescue after a motorist became trapped in flood water.

The rainfall is now thought to be easing across the North Island. Earlier today, New Zealand Met Service said:

“The low that brought heavy rain to Coromandel and BoP is moving away from NZ today. Warnings have been lifted.”
