Chlorination nearly complete

Twenty-two chlorination units are now connected to the areas of Christchurch’s water supply where chlorine is needed.

Five units are to be installed and aim is to have these in place in the next 24 hours.

A boil water notice is still in place, and it is important that residents continue to abide by this until notified otherwise.
This information may have been superseded.
For the latest updates, go to the
Water Services page.

However, once all the units are up and running we can begin planning towards removing the boil water notice.

Security checks for CBD buildings

A group has today been formed that will visit buildings in the CBD and ensure as many buildings as possible are secured.

Civil Defence staff have already gone through the CBD and shut doors. This new group will secure doors and windows that are broken or jammed, where possible.

In some instances, especially where large sections of buildings or windows are broken, it may not be possible to secure these buildings.

Community briefings

More community briefings were held today:

  • South Hagley Park Cricket Ground: 12.00pm to 1.30pm
  • Somerfield Park: 2.30pm to 4.00pm
  • Oaklands School, Halswell: 6.00pm to 7.30pm.

A total of 15 community briefings will be held this week.

More information on community briefings can be found here:

Further areas opening for controlled access

Businesses in Zone 8 (Moorhouse Ave to Brougham Street, Sydenham) with green or yellow placards were today given controlled access to their buildings to retrieve key business items.

After attending at briefing at 1.55pm, business owners were allowed to enter the area for three hours from 2pm.

A portion of Zone 6 will be opened for controlled access tomorrow afternoon. Owners of businesses located between Cambridge Terrace, Kilmore Street  and Manchester St, will be granted temporary access to retrieve key items.

These business owners are being contacted directly.

A northern section of Orange Zone 4 will be opened for controlled access on Friday. These business owners are being contacted directly.

Civil Defence are planning safe corridors to buildings and sections within the Red Zone and controlled access into these areas will begin Monday. This is currently in the planning stage and more information will be provided later this week.

We remind businesses located in the CBD to register on the website. As many records are based on building owners, not tenants, registration will allow us to contact and facilitate access for business owners, where it is safe to do.

So far more than 3500 businesses have registered.

Demolition accreditation process continues

Twenty-three demolition companies have now been accredited.

Accreditation allows Civil Defence to operate a robust management process for all demolitions in Christchurch.

It will ensure Civil Defence has control over demolitions, allowing us to direct the limited demolition resources where they are most needed, and ensure debris, including hazardous materials, is appropriately disposed off.

Demolition contractors wishing to undertake demolition work of commercial buildings across Christchurch, and any building within the Red Zone, requires accreditation.

Demolition contractors undertaking commercial or Red Zone demolitions are not allowed to salvage materials. Where possible, goods of value, such as business equipment, will be returned to the owner or tenant. Building materials will be recycled as much as possible.

Demolitions of residential buildings outside of the CBD should be processed through their insurance company. Owners without insurance should contact (03) 941 8999 or 0800 800 169.

For such buildings the salvage rights can be agreed upon between the demolition company and building owner.

All demolition work requires approval from the National Controller.

We welcome further applications for demolition accreditation. Demolition firms are required to provide an overview of their business, resources capability, track record and relevant experience.

Applications can be made at

Media Advisory – Critical Buildings, 1330, Wednesday, 23 March 2011

Civil Defence is constantly reviewing and updating a list of critical buildings within the CBD.

Critical buildings often need stabilisation or repair. They will not necessarily be demolished and may be taken off the list after further assessment and monitoring.

Critical buildings are generally six or more storey buildings which have suffered damage. Most have a red-placard.

These buildings either

  • house important infrastructure;
  • are on important access routes, such as main thoroughfare roads;
  • or pose a danger to other buildings.

Other critical buildings may need stabilisation, to make them safe enough to give engineers the ability to do a complete assessment.

Stabilisation also enables access to other buildings, which have been restricted for safety reasons due their proximity to the critical building.

Of the critical buildings (37): (as of 21 March 2011)

  • 8 are recommended for probable repair.
  • 3 are recommended for stabilisation for probable demolition
  • 6 are recommended for demolition
  • 13 are assessed as requiring no immediate action by Civil Defence
  • 7 buildings are under current assessment for confirmation of status (repair, stabilisation, demolition, no immediate action)
