A total fire ban was expected to come into place in Whangarei and Kaipara districts at midnight last night.
It will mean lighting any fire is illegal throughout Northland, as a total ban is already in place in Far North.
Until last night, Whangarei and Kaipara have allowed fires by permit only, although with a spate of grass and scrub fires and dry, windy conditions no permits have been issued in recent days.
Whangarei/Kaipara principal rural fire officer Kevin Ihaka said firefighters are frustrated by the outbreak of fires resulting from either carelessness or arson.
Mr Ihaka, who called for the total ban, said he expected it to be in place by midnight Monday.
