Auckland Hospital says it only has one building that is mostly clad in a highly combustible type of cladding.
Six hospital buildings are on a list issued earlier this week by the Auckland Council of multistoreys with either highly combustible or semi-combustible aluminium composite panels.
The fatal Grenfell Tower fire in London a year ago was fuelled by polyethylene core, or PE, panels.
Auckland Hospital's laboratory building on Park Road is mostly clad in PE panels.
"Advice from the Beca Fire Engineer and Auckland Council is that this building presents a low life-safety risk from fire due to the design of the building and the sprinkler systems and other fire safety measures that are in place," the Auckland District Health Board said in a statement to RNZ.
Another five hospital buildings had minimal amounts of aluminium composite panel on them that might be of the PE type, it said.
This included the roof over one entrance to the Starship Children's Hospital.
"Auckland Council has said that no further action is required on all of these buildings as they are of an acceptable safety standard."
A sixth building, the main City Hospital also on Park Road, is partially covered in semi-combustible FR panel on two non-adjacent sides.
"The cladding on our main hospital building is different to what we understand was used in Grenfell Tower as not only is it a different product made by a different manufacturer, but it has a mineral core with lower combustability levels," the DHB said.
