The state of emergency in quake-hit Christchurch has been extended by seven days.
The order, declared on Wednesday, relates to the city only, not the wider Canterbury area.
Mayor Bob Parker says the move is essential for the city's ability to recover.
Curfews in the central city, from 7pm till 7am, were in place on Sunday and Monday.
Aftershocks continue.
Teams assessing the safety of buildings are starting to shift their focus away from the central city into urban areas.
