They were waiting on a fire investigator to confirm the cause of the blaze.
A worker at the site said: "Flames everywhere, me and the other guys try to blitz it out with the fire extinguishers.
"There was too much oxygen in the air so we couldn't take it out."
The building under construction is the Safari Group's Ramada Hotel and Suites Victoria St, a $75m Auckland project with 66 private apartments and 48 hotel apartments.
A spokeswoman for Safari Group said the company would not comment.
