NEW ZEALAND | RAIN | KILL THREE

New Zealand Prime Minister Chris Hipkins said today that torrential rains in Auckland killed three people and left a fourth missing, after flooding devastated the country's largest city.

During a press conference after visiting some of the waterlogged communities, Hipkins said flash flooding had led to "three fatalities with one person still missing as a result of the weather."

"The level of devastation in some areas is considerable," he added.

Hipkins said Auckland experienced "its wettest day on record" on Friday. "This is an unprecedented event in recent memory."

It is his first major incident since Hipkins took office on Wednesday following Jacinda Ardern's shocked resignation.

"Having just surveyed the extensive damage both on the ground and from the air, it's clear it's going to be a big clean-up job," he warned.

Hipkins offered his condolences to the families of the deceased.

"The loss of life underscores the scale of this weather event and how quickly it turned tragic."

Police said Saturday that the bodies of two men were found in floodwaters in separate locations in a northern suburb.

A third person died after a landslide brought down a house near the city center, while a fourth individual is still missing after being swept away in a community south of Auckland, police said.

The flash flooding quickly turned many of Auckland's roads into rivers.

According to MetService, New Zealand's weather service, a record 249 millimeters of rain fell at Auckland Airport in 24 hours from Friday morning local time.

The wild weather temporarily closed the city's airport, the country's largest, with ankle-deep water in some terminals.

The domestic terminal reopened Saturday afternoon, but international flights were only expected to resume on Sunday.

The persistent downpour also washed out Elton John's concert on both Friday and Saturday at Auckland's Mount Smart Stadium amid concerns for crowd safety.

Auckland's Eden Park sports stadium, where the national rugby team plays some of their home internationals, was left flooded, with the iconic pitch under heavy water.

Most of the flood water had subsided by Saturday afternoon, but Hipkins warned that further rain is forecast and advised Auckland residents to stay home.

"It's safer to be indoors than outside." "Look out for each other."

Emergency services have been swamped with calls for help, and Auckland residents have been urged to only contact emergency services if facing "life-threatening" danger.

"We want to get Auckland back up and running as quickly as possible," Hipkins added.
