Te Whatu Ora says health staff are investigating the risk of asbestos after a fire tore through a temporary housing complex in Auckland early Thursday morning - leaving four families homeless.
Firefighters were called to the blaze on Coronation Road in Mangere Bridge about three o'clock.
The accommodation is part of a complex owned by the Pasifika Church and a spokesperson has said up to 30 people were inside.
No one was injured and fire investigators are now trying to determine the cause of the blaze.
Assistant commander and incident controller Chris Delfos spoke to Charlotte Cook.
