6.24pm: All bar one of Mauao's wlaking tracks have reopened.
All the walking tracks on Mauao, except for the Waikorire track, are open to the public. The Waikorire track will remain closed until next week.
Tauranga City Council communications manager Aimee Driscoll said geologists will carry out further remedial work to dislodge any unsafe rocks and boulders on Monday. As a result there may be further temporary track closures in and around the fire site.
However, access around the base track and to the summit is anticipated to be available at all times, she said.
"The fire site is still very unstable and we urge people to stay behind the security fencing, for their and others' safety.
"We appreciate the way the community has responded to the temporary closure of Mauao's walking tracks over the last few days."
12.23pm: Mauao is closed to public until at least 2pm as fire experts continue investigating the origin and cause of the fire that burned on the eastern side of the mountain yesterday.
Tauranga City Council communications manager Aimee Driscoll said investigations were taking longer than anticipated.
Until the NZ police inspector and Pumicelands rural fire investigator complete their investigation council is unable to make an assessment of risk with respect to public access.
She said Waikorire Track is likely to remain closed until at least early next week.
Ms Driscoll said opening Mauao is important but management of risk to operations team as well as the public takes priority.
The council will send further updates around 2pm.
