“My thoughts are with everyone in Auckland as they wake up this morning to assess the damage and face an uncertain day ahead.”

“Auckland was knocked out on Friday – Auckland’s wettest day on record – and today we start the cleanup,” Auckland Emergency Management Duty Controller Andrew Clark said in a statement. .
Emergency services responded to more than 2,000 calls for help, including for people trapped in homes and cars.
