Deadly NZ flood crisis extends in country's north island

New Zealand's deadly flood emergency continued today after heavy rainfall hit the country's north island, causing landslides, flash floods, and knocking out roads.

Auckland, New Zealand's largest city of 1.6 million people, remained under a state of emergency after it experienced its wettest day on Friday (Jan 27), sparking floods which killed three people. Another person remained missing, police said today.

The focus of the emergency has since moved south, with Waitomo District - located about 220km from Auckland - declaring a state of emergency late yesterday.

The nation's weather forecaster, MetService, warned of more severe weather today and tomorrow for the north island, including in Auckland where severe thunderstorms were possible.

Intense rainfall could also cause surface and flash flooding, it added.

Climate change is causing episodes of heavy rainfall to become more common and more intense, though the impact varies by region.

Climate Change Minister James Shaw noted the link to climate change yesterday when he tweeted his support for those affected by flooding.

Today, police said they were assisting with traffic management and road closures in that region after heavy rainfall "caused numerous slips, flooding, and damage to roads".

In nearby Bay of Plenty, there was also "widespread flooding", police said, as well as a landslide that knocked down a house and was threatening neighbouring properties.

"Police are asking those in areas experiencing severe weather to... not attempt to travel on the roads, many of which are currently undrivable," police said.

In hard-hit Auckland, flights resumed at Auckland Airport, which closed domestic and international operations on Friday.

Air New Zealand said the airline's international flights in and out of Auckland would resume from noon today (2300 GMT on Saturday).

Yesterday, Prime Minister Chris Hipkins, less than a week in office, flew by helicopter over Auckland before touring flood-hit homes. He described the flood impact in the city as "unprecedented" in recent memory.

People made more than 2,000 calls for assistance and 70 evacuations around Auckland - the nation's largest city - due to the inundation, the New Zealand Herald reported yesterday.

On Friday, social media showed firefighters, police, and defence force staff rescuing people from flooded homes using ropes and rescue boats.

City rainfall records were broken in the weather event, caused by warm air descending from the tropics, with Auckland Airport logging 249mm in the 24 hours to 9am yesterday, beating the 1985 high of 161.8mm.
