Fire crews working to control a blaze in Matakana say it has not spread overnight.
The fire took hold in the Dome Valley area on Saturday afternoon and has burned through more than 70 hectares of scrub land.
A team of 75 firefighters with two diggers and one bulldozer are onsite today.
One helicopter is providing aerial support and another is on standby.
The Fire Service said all active burning is now within the containment lines.
Bryan Cartelle, Principal Rural Fire Officer, says it is good to see progress but their job is certainly not over.
"The operation is now predominately ground based with the team continuing efforts to strengthen the containments line, put out active flames and dampen hot spots.
"Rugged terrain means this is pretty tough work and I want to acknowledge the dedication of all our volunteer firefighters and partners over the latter part of this fire season."
He said the Auckland fire ban has been in place for a month and the Fire Service expects everyone to be following it without exception.
"Breaches of the ban and careless behaviour will not be tolerated," he says.
Household water tankers which were used to battle the blaze, and have now been released from the operation. He thanked the community for its support.
"Our priority is wrapping this fire up as quickly as we can and also minimising impacts on the community, especially unpleasant smoke and dust."
The Fire Service is investigating the cause of the fire.
The Matakana blaze is the latest in a busy summer for the Rural Fire Service which has been stretched in recent weeks by large scrub fires on Great Barrier Island and Waiheke Island.
