Civil Defence says 55,000 properties are without water (out of a total of 150,000) and approximately 75,000 properties are without sewerage. It's estimated that 75,000 are without waste water.
People whose properties appear undamaged and without siltation can use their showers sparingly.
Functioning toilets can also be flushed sparingly. Toilet waste can be put in rubbish bins as long as it's wrapped in paper or plastic. Kerbside collection for rubbish and organics is continuing weekly but there will be no recycling collection until further notice.

Half of all Lotto sales for this coming week will be donated to help with Christchurch earthquake relief efforts, Internal Affairs Minister Nathan Guy and the New Zealand Lotteries Commission have announced tonight.
Under section 245 of the Gambling Act 2003, New Zealand Lotteries can promote a 'Special Purpose Lottery' for a community purpose.
"Given that the core purpose of Lotto is to raise money for the community, the Government has agreed to this move," Mr Guy said.
"Fifty cents from every dollar spent on Lotto, Lotto Strike and Lotto Powerball next week will be donated to the Christchurch earthquake relief. The March 5 Lotto draw will then take place in the usual way, in accordance with the game rules.
He said New Zealand Lotteries had budgeted to raise $155 million this year for the benefit of the community. It would still be able to reach that target, meaning other community groups will not miss out.
The official death toll for the Christchurch earthquake has risen to 144 this evening.
The number of missing people for whom there are grave concerns remains at more than 200.
It is anticipated limited postal services will resume on Tuesday. In the meantime New Zealand Post is holding all mail.

Police have again warned rubber neckers to stay away from earthquake devastated areas of Christchurch.
People coming from other suburbs to survey the damage wreaked by Tuesday's 6.3 magnitude aftershock are fraying the nerves of already distressed residents, a police statement says.
Minor incidents involving sightseers have flared up, draining resources away from the rescue operation still going on in the city, it says.
It advises people to stay away from Christchurch city centre unless travel is "absolutely necessary".
"Please do not make our job any more difficult, or the lives of local residents any more stressful. The Central City is no place for rubber-necking.
"While police appreciate that it is the weekend, and that people may be curious to come into the area, they urge the public to respect the fact that the Central City is a disaster zone."
Police say they are generally happy with how residents have adhered to public messages and warnings.
Six streets in the earthquake-damaged town of Lyttelton have been evacuated due to danger of rock falls.

He said good progress was made on linking an overhead line to the Brighton substation.
The quake damaged Lyttelton Tunnel is now open for use by local residents.
The tunnel was re-opened at 3pm today, but only to Lyttelton residents because emergency and essential services were still relying on priority access to the tunnel for access to Lyttelton, New Zealand Transport Agency's networks operations manager for Canterbury Pete Connors said.
Christchurch-born and raised actress/director Anna Wilding has started fundraising in the US and abroad for her Christchurch registered charity.

It has made available donation boxes at its properties in Auckland, Hamilton, Queenstown, Adelaide and Darwin.
The Sky Tower has been illuminated red since last Tuesday in association with the Red Cross to raise awareness for their appeal.
AA Insurance is reassuring Christchurch residents that thefts from unsecured homes following Tuesday's quake will be covered by insurance.
"It is important that customers know if you can't secure your home, and you suffer theft as a result, this won't affect your claim. You will be covered," chief executive Chris Curtin said.
A search by Urban Search and Rescue staff has found no-one inside the Grand Chancellor Hotel in central Christchurch.
Structural engineers are now recommending bracing the unstable building to prevent its collapse.
The quake damaged Lyttelton Tunnel is expected to reopen to local traffic by mid-afternoon today after emergency repairs, the NZ Transport Agency (NZTA) says.
NZTA says it is important that only Lyttelton residents use the tunnel because emergency and essential services were relying on it for access.
The tunnel will be periodically closed in order to allow for the safe passage of fuel tankers.
Alternate access to Lyttelton is available for private vehicles via the Dyers Rd pass.
Police say they now have nearly 1200 officers in Christchurch, meaning they can respond easily to normal calls for service.
Superintendent Dave Cliff says two men were last night charged with burglary after being found in a damaged building and will appear in court today.
With the city now "saturated" with at least 600 local police, 324 Australian police and more than 200 from elsewhere in New Zealand, Mr Cliff says there is plenty of capacity to respond to usual calls for Police service.
An unstable building has caused police to close one of the access points in the cordon surrounding Christchurch's CBD.
Police say the access point at the Bealey Avenue/Montreal Street cordon has been temporarily closed and the Art Gallery cannot be accessed.
An initial release incorrectly attributed the closure to a gas leak.
The Canterbury Chamber of Commerce has asked for a $20 million package from the Government to keep business owners afloat over the next month.
Its CEO Peter Townsend says the assistance in September was good, but much more is needed this time around.
"We think the government will need to put aside about $20 million for the first four weeks."
Mr Townsend says the Government will be considering the proposal on Monday.

A number of eastern Christchurch residents are feeling more and more isolated, he says.
"This might be a Saturday, and it might be that we haven't had good news stories we were hoping for in terms of finding people ... but for us this is just as important a day as the first day, the second day, the third day.
"Our approach will continue to be all of the people, all of the skills, to help us work through this tragedy. Our dedication has not moved one iota."

"Everybody is on deck. All hands are on the pump, but you do need to realise the scale of what is in front of us at the moment is utterly immense" he says.
But he says the work that needs to be done dwarfs that following the September 4 earthquake and appeals for patience.
"The work we are doing right now is crucial to the restoration of services across the city."
