A woman, who has asked not to be identified, claimed managers told staff to "just keep working" despite the thick, billowing smoke.

"We have contingency and we are ready to trigger it if required," Ardern said.
"New Zealand has hosted APEC before without an international convention centre... APEC configurations are often quite diverse."
"Because of the way the evacuation was so quick, some [workers] left their tools on site," said Fletcher Building Ltd CEO Ross Taylor.
"We've set up help centres to facilitate and make sure they don't have an issue with those sorts of items they had to leave behind. Once we get back in, we'll be able to return them.

Around 80 firefighters are currently on the scene. Devlin said the fifth floor of the convention centre looks in good shape. He also reiterated confidence that the fire is contained.

4:15pm - Prime Minister Jacinda Ardern arrived at the scene of the SkyCity convention centre fire shortly after 3pm on Wednesday. She has been speaking with firefighters as crews continue to battle the blaze.

2:23pm - Professor John Tookey from the School of Engineering, Computer & Mathematical Science at AUT told Newshub the ramifications of the fire "are set to be huge".

Food and drink donations for the firefighters battling the blaze can be taken to the back of the Auckland City Fire Station on Pitt St.
1pm - One of the reasons for the fire still being alight is that the roof includes layers of flammable straw.
Auckland University associate professor of civil engineering Charles Clifton told Stuff the straw was used for insulation and acoustics.
It was seen to be more environmentally-friendly than other insulation materials.
"The reason the fire's still burning is the fire got into the straw. You've got the layers of straw and the layer of plywood on-top, with a bitumen membrane on it. So it is a flammable panel," he said.
12:50pm - SkyCity is reiterating that its hotels are currently closed and will be on Wednesday night as well.
"No penalties will be incurred for cancelled bookings this evening and affected customers will receive full refunds. To cancel your hotel booking, please do so through the channel you made the booking through," a statement on SkyCity's Facebook said.
12:30pm - Auckland Civil Defence has also released advice for pet owners.
12:20pm - The Headquarters Viaduct bar and restaurant posted on Facebook earlier on Wednesday offering fire crews a place to relax, drink and eat.

"Overnight arrests have been transferred to the North Shore District Court and urgent Family Court without notice applications are still being progressed.

Devlin said he expects firefighters to stay at the site for at least another 24 hours.
11:05am - Fire and Emergency NZ held a press conference.
Regional manager Ron Devlin said the plan so far is "working rather well". That includes letting the roof burn out and fall onto the floor below. Firefighters can then take an "offensive" stance to try and put it out, rather than just stop it spreading.
Devlin said it was a complex fire to deal with, but not the most complex he has had to handle. He expects it to "extend out beyond this evening".
He said there was no concern about the convention centre structure being compromised.

"The ramifications of the SkyCity Convention Centre fire are yet to be established. Losses as a result of the direct effects of the fire are set to be huge," he said.
"The consequential effects of smoke and water damage are likely to be every bit as substantial if not more. When these losses and the business related cashflow impact of cancelled conferences etc are calculated, the final bill could see the sky as the limit."
10:25am - Stephens says staff were fully paid for shifts yesterday and none were asked to take annual leave for evacuating.
10:16am - Fletcher Building CEO Ross Taylor says construction of the building will be finished. He addressed the building team this morning and said there was a lot of emotion on the ground.
"The only way I could describe it is incredibly disappointment."
Taylor said the evacuation on Tuesday went smoothly as it had been practised during earlier stages of construction.
The full impact of the fire and the damage it has caused couldn't be assessed while the flames raged on.
He confirmed a blowtorch had been used on bitumen to seal joints close to where the fire is believed to have started.
10:12am - SkyCity CEO Graeme Stephens told a press conference he expects efforts to contain the fire to continue through the night. He said the fire had been "devastating".

Once the extent of the damage is known, Fletcher Building says it will able to determine the impact of the fire on the construction timeline.
"It is expected there will be a material delay."
9am - Auckland Mayor Phil Goff has spoken to The Breeze's Robert and Jeanette from the Auckland Council building which is near to the SkyCity convention centre.
"My eyes are stinging, my throat is a bit sore. I am going to do a check with the health authorities to make sure that there is nothing that is damaging," he said.
Goff said he expects the fire will push back the convention centre opening by years.
"It is a tragedy for SkyCity obviously, but it is a tragedy for the city. This was our beautiful new international convention centre that was going to be the focal point of APEC."

"We have also been finding alternative options for the events there were due to be held at SkyCity today, including The New Zealand Fine Food Awards.

8am - Weatherwatch says the weather is "not on the side of Auckland firefighters" with gale force winds expected to batter the central city.
"SkyCity is also half way up the main hilly rise in Auckland, this makes it even more exposed to peak wind gusts - meaning gusts on the roof may be even higher than forecast," a statement said.
"This afternoon winds turn more south west and do start to ease, but only a little. Gusts into gale force and up to 80 or 90km/h will be likely across today and don't look set to ease back further until tonight."

7:25am - Fire and Emergency's Ron Devlin told The AM Show it will be at least another 10 hours until the fire is put out.
"We are another 10 to 12 hours, I believe, before we have this fire out."
He said the roof was made up of bitumen, straw and plywood compressed together. There are 80 firefighters at the scene.
Devlin said it was too early to speculate what started the blaze.
7:15am - Auckland Mayor Phil Goff has told The AM Show the situation was "distressing" as smoke continues to billow from the building.
"They have abandoned the roof, that has gone completely. But they are trying to contain the fire above level five of the building."
Goff said a fire commander told him it was one of the biggest and most complex fires he has had to do deal with.
He said it is doubtful the APEC meeting will go ahead in 2021 at the convention centre, but hopes it will happen in Auckland.
"Have no doubt about it, this will be a major setback to the construction programme for this building, which was already running late but starting to look really good."
There is a "plan B" in place for APEC and Goff said he is hoping to talk to the Prime Minister about it on Wednesday afternoon when she arrives in Auckland.

6:30am - Metservice meteorologist Lisa Murray told The AM Show it will be very windy all day in Auckland Central. She said the winds have turned from northwesterly to southwesterly - something that could impact how firefighters tackle the blaze.
She said the intensity of the winds will increase throughout the day, up to about 110km/h around midday.
6:15am - FENZ Auckland regional manager Ron Devlin told Newshub firefighters believe they are in control of the blaze.
"I believe we have control of the fire. We obviously have eyes on it and we have a plan as to how we're going to actually contain it. In looking at the fire itself [you] probably [wouldn’t] think that."
