One person has been injured in a chemical fire, which caused staff to be evacuated from a Countdown supermarket at Warkworth north of Auckland this morning.
A Fire Service spokesman said a rubbish bin was on fire outside the supermarket, which is believed to have been caused by tubs of a chlorine product splitting open at about 5.30am.
He said St John are at the scene after a staff member complained about "sore eyes and a burning face".
Fire crews have managed to put the fire out.
