A man pulled a knife on two others during a fight in front of a Parnell boarding house that was engulfed by fire.
A neighbour of City Garden Lodge said she saw three men fighting on Sunday afternoon as fire tore through the property before one man pulled a knife.
She told the Herald she had issues with residents of the lodge who often cursed and threatened both her and other neighbours for more than three years.
She understood the fire was lit among one of many weekly fights at the property.
Another neighbour said the building was home to many parolees and others who were just “down on their luck”.
This morning a police scene guard was in place, with fire investigators returning to determine the cause of the blaze.
There are now fears for the future and safety of the historic boarding lodge, which was due for a fire safety audit tomorrow.
Police and fire investigators are today combing through the wreckage of Sunday’s fire to determine how the blaze started at the backpackers hostel in St George’s Bay Rd.
Auckland Council building compliance workers are also on site to see if the building will be able to be lived in again.
Deputy Auckland Mayor Desley Simpson said this morning the Parnell building was due to have its building warrant of fitness checked tomorrow.
The building had passed checks in August and November.
Ten crews remained on site overnight dealing with the wreckage of the City Garden Lodge.
A police scene guard was in place overnight, with fire investigators to return this morning to determine the cause of Sunday’s fire.
At its peak, 16 fire appliances were needed to fight the blaze, which sent flames 6m high and smoke billowing across the city, leaving residents struggling to breathe outdoors.
Fire and Emergency was first alerted shortly after 4.30pm through the lodge’s alarm system, before receiving calls from the public, scene incident controller Assistant Commander Gary Lane said.
“The fire has engulfed the attic area and spread down to the first floor,” he said.
“Our crews have been using a ladder truck to pour water on the fire and this seems to have knocked it back well ... The fire is now contained, but crews will remain on standby overnight,” Lane said.
Police also arrested one person after a “disorder” incident at the same address, but later released them without charge.
Fire and Emergency NZ received an initial call to “persons reported”, meaning there was possibly a person still in the building, Lane told a Herald photographer at the scene.
“We still haven’t been able to locate one of the occupants and we’re still in the process of trying to find them.”
However, police said there were no immediate concerns about anyone remaining in the building.
A witness told the Herald flames appeared to be about “20ft [6m] high”.
“It is absolute chaos here. There is thick smoke all over the street ... we went outside but were told to go back in because we couldn’t breathe,” they said.
The resident said they saw people fighting outside the property that was on fire and one person was arrested.
Police said this morning their investigations were also continuing into the fire’s cause.
