A third of Christchurch households remain disconnected from the city's water supply following last week's earthquake.
Water had been restored to 67 per cent of households and tankers were delivering water to areas without supply.
People were reminded to boil all water before drinking, including tanker water, de-salinated water and normal tap water.
If people were unable to boil they were advised to add 1 teaspoon of bleach for every 10 litres of water and leave for 30 minutes before drinking.
Canterbury District Health Board (CDHB) advised people to stay away from all beaches between the Waimakariri River and Lyttelton Harbour, which were contaminated with sewage.
"Testing has confirmed that water at some Christchurch beaches is contaminated at levels that could make people very ill from contact," said medical officer of health Ramon Pink.
It was "extremely important" for people to follow this advice due to the risk of gastroenteritis outbreaks, Dr Pink said.
Universities and other tertiary institutions in quake-ravaged Christchurch are making alternative arrangements for their students, including a chance to study abroad, following last week's 6.3 magnitude tremor.
Canterbury University today announced up to 500 undergraduate students would be given the opportunity to spend one semester at The University of Adelaide in Australia.
The students would not be charged any additional fees but would have to pay for their accommodation.
University of Adelaide vice chancellor and president James McWha said the two organisations had a special relationship having collaborated on a number of projects.
"Our sympathy and understanding extends to the people of Christchurch, and we see this as an opportunity to strengthen the ties between our two institutions at a time when it is most needed," he said.
Speaking in Christchurch today, Canterbury University vice chancellor Rod Carr said while a semester abroad was a fantastic opportunity for a small number of students, many others also needed support.
"Recognising that some of our buildings may take a little time to access for their structural integrity, and that we already know that some of those spaces will not be available to us, we are today commissioning the build of 8000 sq m of single-storey space on the university oval," he said.
The news buildings would be up and running in eight weeks, with spaces for lectures, seminars, study groups and staff offices.
Prime Minister John Key says an Israeli search and rescue group which was refused entry into Christchurch's inner-city cordon following last week's quake was not a United Nations approved team.
The rescue team was organised by the families of Ofir Levy and Gabi Ingel, who were both killed in last Tuesday's quake.
Hilik Magnus, a member of the team sent over by the families, told Israeli newspaper Haaretz he was annoyed they were not able to help.
"The fact that they are ignoring us, a group comprised of individuals with internationally renowned experience is inexplicable, and cannot be comprehended," he said.
But Mr Key said this afternoon the group was not United Nations accredited.
"The Israeli team was not part of a UN-accredited team, it was a private group organisation put together, he said.
"We have had a wide range of offers of help, and we've largely taken those, but we've also said no to a lot of teams because we feel we have enough people on the ground."
Mr Key said he had been in contact with Israeli Prime Minister Benjamin Netanyahu about the two Israeli citizens whose bodies were located in the Manchester Street area.
Their bodies, along with that of a third Israeli citizen killed in the quake, had been returned to Israel.
Ofir Levy's father Moti Levy earlier told NZPA the family was devastated when Israeli police told them Ofir had died in the quake.
"We are trying to cope and to start to imagine how we can live without our son," Mr Levy said.
The Fire Service fears strong winds may bring down the historic Time Ball station in Lyttelton, Radio New Zealand reports.
Lyttelton's chief fire officer, Mark Buckley, told the broadcaster he was called to the building by people working on site who believe the station has moved since the earthquake.
He says the station appears to be very unsound and vulnerable to strong winds.
Only one home is believed to be in its path and the road below it is already closed because of the earthquake.
It is one of only a handful of surviving time ball stations around the world.
Christchurch Mayor Bob Parker has also said it was too early to comment on when the CBD will be opened, but "I'm determined that as much of the CBD will be opened as quickly as possible".
But One News reported that Central City Business Association manager Paul Lonsdale estimated up to 60 per cent of the CBD's buildings might have to be knocked down.
Some Christchurch people are getting too possessive with the portaloos in their street.
With water supply and sewerage systems out in many areas of the earthquake-torn city, community portable toilets have been placed in many streets.
"In some cases...someone has taken a particular shine to a portaloo...and they have pulled it up their driveway in order to have frequent and free access to it," Mayor Bob Parker said today.
"I am sure that is great for the person who gets it closest to their back door but to all intents and purposes it disappears off the streets."
There were a few cases reported of this happening and Mr Parker asked residents to handle it at a local level.
"Can you just knock on your neighbour's door...and actually suggest to them that is a very anti-social thing."
More than 5000 analogue phones have been distributed to quake-affected Christchurch residents - and more are on the way.
Telecom had a "fantastic" response after asking New Zealanders to donate their old telephones so those without power were still able to make phone calls, Telecom chief executive officer Paul Reynolds said.
Meanwhile, more than 55,000 calls have been made from 260 free Telecom payphones around Christchurch.
Free gas cylinder refills will continue to be available at three Christchurch sites until Friday, but free refills at other sites will not be available after 5pm today.
Contact Energy has refilled more than 12,000, 9 kilogram cylinders since Friday last week to help those devastated by last Tuesday's quake.
Contact managing director David Baldwin said free refills would now just be available until Friday 5pm in areas of the city which had been most impacted by the earthquake.
"We want to help where we can, and there is not a person in the Christchurch community that doesn't need support. However as the needs of the worst hit areas of the community emerge, our support will increasingly move to where need is greatest."
Filling stations open until Friday 5pm are -
* Butler Automart in Richmond.
* Mobil Wainoni.
* Contact Rockgas in Sydenham.
Earthquake recovery minister Gerry Brownlee has dismissed reports Christchurch city centre will not be open for months as "speculation".
Christchurch Central City Business Association manager Paul Lonsdale was reported earlier today saying it would be "some months" before parts of the CBD were accessible to the public.
Mr Brownlee said there was no timeline in place for how long it would take to reopen the CBD.
His officials would not assess that until the bodies of all those who died there in last week's earthquake had been recovered, he said.
"There are still trying to recover bodies in there. I don't have time for endless speculation."
Satellite pictures of earthquake-damaged Christchurch have been taken by Google Earth partner GeoEye, showing the extent of some of the destruction.
The GeoEye-1 satellite passed over Christchurch on Thursday, two days after the 6.3-magnitude quake struck the city.
Some parts are covered in clouds but substantial portions of the central business district are clearly visible.
The images can be viewed on Google Earth, which needs to be installed on your computer, or a selection can be seen on the Picasa website at this link.
The earlier images were taken in 2009.
Canterbury DHB chief executive David Meates has invoked memories of Hurricane Katrina to justify evacuating hundreds of elderly out of the Christchurch in the wake of last week's earthquake.
Many frail elderly were not moved out of unsafe facilities in the aftermath of the devastating hurricane that hit New Orleans in 2005.
Many died, while others endured horrific sanitary conditions while waiting for evacuation.
Mr Meates said that memory was in his mind when he decided to evacuate more than 300 residents of rest homes around Christchurch.
Staff were taking care of elderly in damaged buildings and high pressure conditions, he said.
"I want to assure everyone that the decision to move residents was not made lightly. I know staff are feeling very upset about the way they have had to operate, without the luxury of time to work with families as they usually would.
"They know just how fragile many of the resthome residents are, as they care for them day in and day out. In many cases, they have been working in facilities where it was just not possible to keep residents safe. We can not, and will not allow vulnerable people to stay in situations of avoidable risk."

A Japanese television reporter's media accreditation within the Christchurch central cordon has been revoked after he shouldered Canterbury police commander Superintendent Dave Cliff this morning.
The incident happened at the end of an interview and came out of the blue, a police spokeswoman said.
It was not clear why the reporter was upset. He had not been charged but such behaviour would not be tolerated, she said.
The shouldering was definitely not an accident. If it had been he would not have had his accreditation revoked, she said.
There are about 500 accredited media from around the world in Christchurch.
Civil Defence manages the accreditations and a spokesman said he was only aware of one reporter having accreditation revoked.
The New Zealand contingent had been exceptional and very respectful, the police spokeswoman said.

One in three commercial buildings in the centre of Christchurch may be demolished after last week's earthquake, says Prime Minister John Key.
For every one of those buildings to be demolished, geotechnical work would have to be done on the land, possibly with deep piles to reach solid ground, Mr Key told Newstalk ZB today.
The rebuild of Christchurch would be "a 15-year job", he said.

He says workers took five minutes out for the "lovely ceremony" at 5.30am.
"There were quite a few tears shed and when that finished they went back to work."
Mr Gibson says some of the personnel worked through the night so had missed yesterday's two minutes' silence and wanted to pay tribute.
"I think it was their way of reflecting on the horrendous job that they had been doing."
Rescuers at the site still hope to find survivors, he says.
"There's always hope - they live on that - but the reality is it fades."
