Insulation and tiles recovered from the building failed fire safety tests, they said.
"The government has ordered an immediate examination of this unit by technical experts to establish the cause of the incident".
Auckland Council is looking into the cladding on 90 high-rise buildings in the wake of London Grenfell Tower disaster.
DS McCormack said they are now carrying out further tests in relation to the Hotpoint FF175BP fridge freezer model, which had not been subject to any product recall.
"We can not and will not allow people to live in unsafe homes", she said.
Manslaughter charges are among a string of offences being considered by police as part of the investigation, Ms McCormack said.
"We utterly condemn the requirement being placed on residents of Grenfell Tower to sign a declaration in order to receive an emergency payment of £5,000 which refers to the payment as "compensation" and states nothing to protect the rights of those who receive it", the lawyers said in a statement to the Guardian.
Auckland Council says the buildings are being re-cladded, but not for fire-related reasons.
It has been discovered that non-compliant material with a flammable polyethylene core was used for Grenfell Tower's cladding even after 16 inspections made by Kensington and Chelsea Council during renovation works from 2014 to 2016.

Mayor Karen Weaver said in a release the situation was "under control" but that officials sought to take "extra precautions". Law enforcement agencies in both the United States and Canada are working together to find more information on the suspect.
The statement continued: "Words can not express our sorrow at this awful tragedy".
Mr Corbyn compared the tragedy with the Hillsborough disaster and child abuse scandals, saying: "The pattern is consistent: working-class people's voices are ignored, their concerns dismissed by those in power".
Answering May's call that none of the victims should live in unsafe homes, the Corporation of London said families who lost their homes in Grenfell Tower will be housed in a complex of sleek new apartments in Kensington, a measure which received mixed reactions.
At least 11 public housing blocks in eight locations including London and Manchester have already been found to be covered in combustible material, local government minister Sajid Javid said yesterday in a letter to MPs.
The Mayor of London Sadiq Khan also expressed support for a complete amnesty for immigrants who may have been living in the tower illegally at the time of the blaze.
"Preliminary tests on the insulation samples collected from Grenfell Tower showed that they combusted soon after the fire started", she said.
The council has been checking buildings around the city to find out how many have the particular type of panel which has been implicated in London's Grenfell Tower blaze that claimed at least 79 lives.
'We are also concerned about the fridge freezer in this matter and we have been working with the Department for Business, Energy and Industrial Strategy, who are working with Hotpoint on the safety of that fridge.
