About 80 per cent of earthquake-ravaged Christchurch remains without water.
But Christchurch Civil Defence and Emergency Management (CDEM) has urged people to stay at home unless it's absolutely essential to leave.
All schools and many workplaces will remain closed until the weekend, CDEM said.
With 80 per cent of the city without a water supply on Wednesday night, authorities advised everyone to conserve it by not washing or flushing their toilets.
They were advised to collect water in buckets when it rained and boil all drinking water.
On Wednesday there were 14 locations across the city where people could get fresh water.
Boiled water will be available at another nine sites from 6am on Thursday.
Another 34 water tankers are due to arrive in the city on Thursday.
Power has been restored to a little over 60 per cent of the Christchurch area.
Meanwhile, welfare centres are providing people with blankets, food and sanitation.
By midday on Thursday, 220 search and rescue personnel will be deployed in the city and as many as 700 personnel could be deployed within the next 48 hours.
Business and building owners have been advised to stay away from the badly damaged CBD.
Weather events should cause us to remember that the God who created the world also controls the weather conditions and often uses weather as a method of judgment against sin. Plenty of examples are seen in the Scriptures: Worldwide Flood (Gen 6-9), Volcanoes burning down Sodom and Gomorrah (Genesis 19), and Earthquakes and Plagues (Numbers 16). If the God of the Bible can control the wind and the waves (Mark 4:35-40), and will someday judge the world with Catastrophic world weather events including earthquakes and and comet showers (Revelation 6:12-17), earthquakes like these should cause us to take notice.
Some other examples in scripture include the use of drought, darkness, hail, and violent storms.
Last, but not least, don't forget the coming day in which God will judge the world in righteousness as "the heavens and earth now being preserved by the same word, are reserved for fire until the day of judgment and perdition of ungodly men" (2 Peter 3:7).
Great Picture of God at Work: God parting the clouds. A picture that reportedly has been seen in multiple sites across the south over the past few months.
And God will wipe away every tear from their eyes; there shall be no more death, nor sorrow, nor crying. There shall be no more pain, for the former things have passed away.
