Auckland Council is looking into the cladding on 90 high-rise buildings in the wake of London Grenfell Tower disaster.

The council says it has already identified two apartment buildings clad with aluminium composite panels - a building material used on the Grenfell Tower block which burnt down nine days ago in London.

At a press conference this afternoon, a council spokesperson said the two buildings are 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 confident other buildings were completely safe, the spokesperson could not confirm this.

Of those 90 buildings it had identified, 21 are being actively reviewed.

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".

Ian McCormick, Auckland Council's building control general manager, 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.
