The two Auckland buildings identified as having combustible cladding have been named.
TVNZ reported the buildings were the Spencer on Byron in Takapuna and the Nautilus in Orewa.
Auckland Council started looking into the cladding on high-rise buildings in the wake of London's Grenfell Tower disaster.
The council said it had already identified 90 buildings of interest and had reviewed 21 of those.
So far, two privately-owned apartment buildings had been found to be clad with aluminium composite panels - a building material used on the Grenfell Tower block which burned down nine days ago in London.
At a press conference this afternoon, Auckland Council general manager building control Ian McCormick said the two buildings were currently being reclad for weathertightness issues, rather than fire safety concerns.
The council would not identify the buildings as the occupants still needed to be told.
It couldn't comment on reports that occupants of these buildings were being moved out.
When asked if the council was confident other buildings were completely safe, McCormick could not confirm this.
The council also couldn't confirm when it would have a final number of buildings that may have the cladding, saying it was working through the process.
In the wake of the London fire, Building and Construction Minister Nick Smith asked the Ministry of Business, Innovation and Employment "to contact councils and check whether any high-rise buildings have been constructed with these materials".
McCormick said earlier this week that even though Auckland had buildings with aluminium composite panels (ACP), they were not necessarily dangerous.
"Following a survey and documentation review, we identified a number of buildings around the Auckland region that interested us and have found less than 100 that use ACP panels. This is across a range of building types and in some cases it is used as a small design feature, rather than cladding an entire building," McCormick said.
The council had already taken action after Melbourne's Docklands fire two years ago, he said, and was not just reacting to the London fire and MBIE's call, he said.
Investigations were not complete and full findings might not be out for some months.
