Another cordon has been lifted in central Christchurch, with access to streets east of Manchester St opened.
The move, just confirmed, is the second and smallest of four cordon reductions planned in coming weeks.
A Canterbury Earthquake Recovery Authority (Cera) spokeswoman said a cluster of dangerous buildings between Bedford Row, Madras, Manchester and High streets will stay behind a safety fence as there were still concerns about their stability.
Once the buildings' owners have dealt with those issues, the safety fence's placement will be reassessed.
"Owners and their engineers can access the area as required to complete the necessary works, but any reduction of the safety fence will rely on their efforts,'' she said.
The owners had had several months' notice of the impending cordon change, the spokeswoman said.
While the cordon has been lifted and New Zealand Defence Force staff no longer manage the area, parts of the roads will stay closed as repairs continue above and below ground.
Christchurch City Council transport and greenspace manager John Mackie said this was necessary work, but it would be frustrating for some.
"We haven't started work until now as that would have held up the ability to demolish buildings or work on building repairs, and that would have been impractical,'' he said.
"Our role now is to address the roads, footpaths and infrastructure that need work as the last step in this process.''
