This means it could be up to four months before the occupants – who are currently staying in hotels, alternative Andium properties or with friends and family – are able to move back in.
He added that the remaining seven were damaged “to a lesser degree”, with those residents likely able to move back in “weeks, not months”.
Almost 60 households were initially evacuated when unmanageable rainfall overwhelmed the island’s drainage system and caused water to rise to waist-height in areas of the Andium estates.
A major incident was declared and, in some cases, an inflatable raft was used by emergency service crews to get residents to safety.

Mr Mavity said that contractors and repair teams were onsite everyday while the clean up effort continues.
“For those who are most affected we are looking at more permanent accommodation – those conversations will take place on an individual basis,” he continued.
“The fundamental thing is making sure [the properties] are dried properly, repaired and that new floor coverings are put down so that it is safe for them to move back in.”
