4.38am: Auckland Airport says travellers are beginning to head home as floodwaters recede.

More than 2000 travellers and airport staff had been cut off by flooded roads around the airport precinct, the airport said in a statement.
"This is not the start any of us wanted for the long weekend in Auckland. We want to genuinely thank travellers for their patience overnight, as we contended with rising floodwaters, a runway closure and multiple flight delays, diversions and cancellations," said chief executive Carrie Hurihanganui.
"We’re also really grateful to the retailers that remained open tonight to support travellers and provide food and drink, as well as our team at the Strata lounge and other airport lounges who have worked through the night to care for travellers."
A number of passengers are still waiting airside at the international terminal. Auckland Airport said it would be working with borders agencies to help those travellers through formal border processing formalities before they could depart.
"Due to the damage overnight and the need to check key terminal infrastructure, no domestic or international flights will be arriving or departing from Auckland Airport before noon Saturday, 28 January."

Travellers have been encouraged to get in touch with their airlines for the most up-to-date information.

Drivers are being urged to remain patient as the traffic backlog clears.
2.58am: Prime Minister Chris Hipkins says his advice to Aucklanders is to be kind to one another.
"While the emergency teams are doing their best, in many cases, their mobility is also currently restricted."

12.08am: Elizabeth, Sam and Zoe Jansson-Bush were due to depart for Stockholm via Dubai at 9.15pm for a funeral but have had their flight postponed.

Elizabeth told 1News they are getting regular updates about every hour and at this stage are being told no one can go in or out of the airport and the air crew for their flight were not able to get into the terminal.
"Basically their explanation is that no one can go in and out of the airport, and they were told the air crew that were late because of the flooding and heavy traffic were not let through security.
"So everyone is stuck inside regardless of whether the flight is cancelled or not. The only food places open are McDonalds and a convenience store, so everyone is queuing for those."
"No one is allowed to leave and we have to stay upstairs."
She said there were no updates about when they can leave or when their flight will be available.
The siblings have been at the international terminal since 5pm. The funeral they are travelling for is on February 4, so they are hoping they will still make it.
"I have no expectations at this point. We are going to wait here until further updates and plan accordingly.
"We are lucky we are indoors and dry and it sucks we’ve had our flights cancelled, but people out west have it so much worse," Elizabeth said.

"The flooding has made it difficult for our crews to safely reach some of the outages, including in the Swanson area, and they will be unable to do so until the water has gone, hopefully by the morning.
"We urge everyone to take extreme care, avoid floodwaters and stay well clear of fallen power lines or damaged electrical equipment, and treat them as live at all times.
"We would like to thank everyone for their understanding and patience as we work within the limits of what is safe and practical to restore power as soon as possible. Our thoughts are with the many Aucklanders who are facing challenges caused by the extreme weather."

3.20pm: Auckland Transport has apologised after a Facebook post last night suggested revellers heading to the Elton John concert tonight and tomorrow should drive in following the partial closure of the rail network.
"We want to reassure Aucklanders there is a full transport plan in place, which provides for a range of options. Via the promoted we have reinforced these options to all ticketholders," Auckland Transport interim chief executive Mark Lambert said in a statement.
"We apologise for the confusion this has caused. We have since updated the post.
"Given the partial closure of the rail network by KiwiRail tonight and full closure on Saturday night, the plan is similar to that used for the Billy Joel concerts at Eden Park, with greater capacity on bus special event services and extra options for parking."
