The March 8 census has been cancelled following the 6.3 magnitude earthquake in Christchurch, Statistics Minister Maurice Williamson says.
Announcing the decision in Wellington this morning, Mr Williamson said holding the census would be unfair to the people of Canterbury and that the data might not be reliable.
He said Government Statistician Geoff Bascand had informed him that the 2011 census could not be completed successfully.
There had been extensive damage to Statistics New Zealand buildings with significant impacts on census staff, Mr Williamson said.
"This is not the time to go door to door asking New Zealanders for information when they're dealing with the aftermath of the earthquake," he said.
"It's unthinkable that we would ask this of people. It would be an unfair burden and distraction at a time when they are grieving."
Mr Bascand said 7000 people had been hired to conduct the Census and Statistics NZ would meet its contractual obligations.
A census costs $90 million over five years and $42 million had so far been spent on the the one that has now been cancelled.
Mr Bascand said the decision would have consequences for people who use the census data in their work.
"We will now investigate the feasibility of alternative options," he said.
The death toll from Tuesday's earthquake rose to 113 today.
Civil Defence Minister John Carter said he understood the last "live rescue" of a survivor had been about 3pm on Wednesday.
"We are still hopeful there will still be people rescued but it is becoming unlikely," Mr Carter said.
Mr Carter said rescuers would "just continue on with the search until we are satisfied there are no more bodies to recover".
"It is not until you are down in Christchurch that you have an appreciation of the devastation - it is unbelievable."
Rescuers' energies were currently focused on where they know the bodies were, he said.
But Mr Carter said the teams would today begin conducting grid searches of places such as alleyways where they suspected people might have been trapped by falling rubble as they went to and from lunch on Tuesday.
Mr Carter said search and rescue workers in Christchurch were doing an "amazing, outstanding job" and were releasing information as quickly as they could.
"One of things we do need to understand is the teams of people working down there are doing an outstanding job. They are doing everything they can working day in day out.
"These people - a lot of them have their own family and personal issues to deal with.
"They are heroes."
Four officially named
Police Superintendent Dave Cliff last night read the names of four earthquake victims, including two babies: Jayden Harris, 9 months, and Baxtor Gowland, 5 months.
Among the missing are 122 people believed to be inside the Canterbury Television building.Police earlier described the damage to the building as "100 per cent unsurvivable".
Hope for more survivors in the PGC building was extinguished yesterday.
While there had been several successful rescue attempts, chief executive Jeff Greenslade said 10 Perpetual and four Marac staff were left behind.
Emergency teams told him the rescue effort was now a recovery mission.
About 22 people, mainly tourists, still lay unrecovered in the ruins of the Christchurch Cathedral.
The tragedy has had effects far beyond New Zealand - among the missing and dead are international visitors including Chinese, Japanese, Taiwanese, Filipinos and Britons.
Cleaning up the streets
But as rescue efforts moved to the heartbreaking work of recovering bodies in the city, survivors got on with backbreaking work of cleaning up their stricken streets.
John Key flew over suburban Christchurch yesterday and said in pockets the devastation was worse than in the central city.
"While we don't have perfect numbers, it's highly likely that there will be more residential properties that will be uninhabitable than in the [September] earthquake, and that was 3300."
The suburb of Bexley was wallowing in liquefaction from the September earthquake. This time, the damage is worse.
Residents grabbed spades and were again shovelling and scraping the charcoal grey sludge covering their homes, driveways and roads.
Despite the hard work, Donna Jackson was bright and friendly and summed up why locals were smiling through their pain. "Because we're not dead."
