The national state of emergency has been extended until next Monday, in the aftermath of the 6.3-magnitude earthquake that struck Christchurch on 22 February.
Civil Defence Minister John Carter said work remains focused on residents being adequately housed in safe and warm accommodation, with reliable access to water, functional sewerage disposal, electricity and communications.
"Given the extent of damage to the city, good progress has been made in restoring lifelines and now 99% of people outside the Central Business District have power and 100% of households outside the Red Zone have running water.
"To put this in context, on 25 February 50,000 people (approximately 20%) were without power and between 50 and 60% of households had no running water," said Carter.
He said once the Canterbury Earthquake Recovery Authority has been set up there will be a hand-over from the National Controller to that organisation and the state of national emergency can be lifted.
Under the Civil Defence Emergency Management Act 2002 a state of national emergency can be declared for a maximum of seven days at a time only.
