11.30am: Once debris have dropped down, crews will then be sent into the building. The timeframe for that is three hours, Mr Devlin said.

11.28am: Further to Mr Devlin's stand-up, he said crews were currently in a defensive position but the plan was to sacrifice the roof and let debris drop down to the fifth floor, which would allow crews to move into an offensive position.

11.20am: That brings the media conference to an end, we'll have video of that shortly.

11.18am: Mr Devlin says 70 per cent of the roof is on fire and the plan is to let it all burn, which will cause it drop down, making fire fighting efforts easier.

11.15am: The fire started on the north-eastern corner of the building.

11.12am: We're in the best position to fight the fire with five aerial appliances pumping 60 litres a second, Mr Devlin has said.

11.11am: Firefighters feel safe combating the blaze, despite one of them being taken to hospital ill yesterday.

11.10am: I don't have any particular concerns about the structural integrity but firefighters are working to keep it that way, says Mr Devlin.

11.05am: The plan is going well so far, a fire chief Rod Devlin said. The plan is to sacrifice the roof and let the debris drop down.

10.33am: Mr Taylor does not want to speculate further on the cause of the fire, saying speculation can be dangerous.

10.31am: The person who spotted the fire saw a bitchumen product on fire on the roof. Protocol says workers should raise the alarm if the blaze is bigger than a certain size, rather than make an effort to put out the fire.

10.29am: The insurer is an international company, says Mr Stevens, who is confident in the credibility of the company.

10.19am: One of the foreman spotted the blaze, Mr Taylor has said. It took 20 minutes to evacuate the building. He said speaking about the cause of the fire would be speculation.

10.16am: We have insurance policies in place, they have been taken out by SkyCity, Mr Stevens has said.

10.16am: It is probably the first time in company history that the company's hotel and restaurants have been shut down.

10.15am: It is impossible to estimate what the cost of the fire will be, Mr Stevens has said.

10.05am: He said the conservative decision was made yesterday afternoon to evacuate SkyCity's buildings.

Stations are recording gusts of 95 to 120km/h with southwesterly winds potentially strengthening in the next few hours before easing off later this afternoon, Metservice has said.

9.51am: Fire and Emergency have put out this comment a short time ago. "Helicopters with monsoon buckets are a firefighting tactic predominantly used for vegetation fires and very rarely used for building fires."

They will undertake their own investigation, as well as assisting with any other agencies' investigations as required.

8.46: SkyCity has said in a statement that they will not open any of the buildings in their precinct today, including the Sky Tower, Casino, Convention Centre, hotels and restaurants.

8.09: The weather in Auckland this morning is forecast to include hailstorms as well as a moderate chance of thunderstorms. Winds are forecast to be high, MetService says, with gusts of up to 100kmh in exposed places. The high winds are encouraging the SkyCity fire to burn more fiercely.

“Winds are due to get up to 30 or 40 knots later in the morning,” regional area commander Ron Devlin tells Breakfast host John Campbell. It's “an extremely difficult fire to fight. We’re currently facing an extreme weather warning as well.”

"We couldn't get people on the roof because of safety."

6.54: Mayor Goff on the setback the fire has caused to the convention centre project: "It may take years to get back to where we were." The strategy, he says, is now to keep the fire from spreading below level 5. "All credit to the firefighters. We owe them a huge debt."

6.15am: Firefighters say the building can be saved. But authorities said they'll know in the next 24 hours how much damage has been done. The site was scheduled to host APEC in 2021. The massive construction project, however, has been beset by delays.

6.10am: About 30 fire engines remain on scene. Firefighters tell TVNZ1's Breakfast they will have the latest assement on the damage caused by the blaze overnight in about an hour.

6.05am: TVNZ's Auckland CBD building and TV studio has been evacuated. Breakfast, however, will be on air this morning with the latest.

5.30am:

Firefighters again lost control of the large fire at Auckland's SkyCity International Convention Centre overnight as it continued to burn.

Around 100 firefighters and 21 fire engines remain at the scene of the blaze, which ignited around 1.30pm yesterday.

Fire and Emergency New Zealand are in defensive mode as they allow the roof of the building to burn through.

"The level seven roof has been fairly much consumed," Coiunties Manukau area commander Jeff Purcell told 1 NEWS. "The fire is travelling in between the roof service and the ceiling space through compressed straw insulation, soundproof, sound deadening panels, and this is proving extremely difficult to even see where the fire is.

"It's bursting out all around the place up on level six and seven, and we're really trying hard to contain it."
