Heavy rains caused flooding in Auckland, New Zealand

Heavy rainfall of up to 90mm in one hour hit northern New Zealand, forcing dozens of families to evacuate their homes.

Between fifty and sixty homes were evacuated in West Auckland after flooding on the night of August 30-31, 2021.

Oakland Mayor Phil Goff said people mostly evacuated on their own and stayed with friends and relatives. Evacuation centers have also been set up. The Oakland Office of Emergency Management said the need to evacuate overrides COVID-19 lockdown rules.

Up to 90 mm of rain fell in 1 hour. However, Mayor Goff said the flooding was largely unexpected. “We knew it was going to rain … but there was no early indication that it would cause the level of flooding that it is now.”

As of Aug. 31, flooding had affected communities in Kumeu, Wapai, Ranui, Piha and Henderson Valley. About 12 roads were closed as a result of flooding and landslides. About 13 people were rescued from the floodwaters by rescue services, which received 150 calls for help. The mayor said fire, police and emergency services are handling the situation and there is no need to declare a state of emergency.

In the 24 hours to Aug. 31, Kumeu received 208.2 mm of rain, the second wettest day in the city since 1943 and 149 percent of the monthly rainfall.
