At a press conference a short time ago, Counties Manukau DHB chief medical officer Dr Peter Watson outlined the need for dressings and temporary skin grafts.
An additional order has been placed with American skin banks to cope with the demands on New Zealand's burn units.
Twenty-two patients remained on airway support, Dr Watson said.
"We anticipate we will require an additional 1.2 million square centimetres of skin for the ongoing needs of the patient."
That equates to 120 square metres of skin.
