A fire ban is in place for the entire Auckland region including the islands of Great Barrier, Kawau and Waiheke in the Hauraki Gulf from Friday.
The Rural Fire Service says the forecast for a hot, dry long weekend with strong winds means a fire ban is the safest option.
All fires in the open air including rubbish fires, bonfires, backyard braziers, fireworks and cooking fires are banned.
The ban will remain in place until the fire danger is no longer classed as elevated.
The ban was announced as crews continue to battle a large blaze on Great barrier Island burning since Tuesday morning.
