Flooding can happen without warning and when we least expect it. If you've been flooded it's important to drain, dry and clean your home quickly. Further information on cleaning up safely is available below.

If you feel unwell after coming into contact with floodwater or contaminated items contact your doctor, or call Healthline for free on 0800 611 116. In an emergency call 111. |
While it is important to drain, dry and clean your property as soon as possible, you should also make sure it is safe to enter and you are suitably protected.
Before you start cleaning up you should put on protective clothing and ensure you have suitable gear.
During the clean up avoid bringing footwear and clothing into the house that has been in contact with waste and debris, until it has been thoroughly disinfected.
All floodwater and flood waste should be assumed to contain sewage. Sewage contains harmful bacteria and viruses and needs to be cleaned up as soon as possible. Keep children and pets away from the area until this is done.
Put on protective clothing and ensure you have suitable gear prior to starting (see advice in Before cleaning up).
Floodwater can carry bacteria, chemicals and other hazards that can contaminate food, as well as cooking areas and utensils. You will need to carefully dispose of items and clean up areas that have been in contact with floodwater.
Put on protective clothing and ensure you have suitable gear prior to starting (see advice in Before cleaning up).
As surfaces and utensils may have been contaminated during the flood, it's important to clean up carefully afterwards:
You can keep food that has been in tins, but make sure they are thoroughly cleaned before opening by:
Drying and cleaning flood damaged properties as soon as possible will reduce the risk of mould and fungi damage. These can cause damage to your property, and also have significant health risks.
Put on protective clothing and ensure you have suitable gear prior to starting (see advice in Before cleaning up). It's recommended you wear at least an N95/P2 face mask when cleaning up mould in your own property. These are available from hardware shops and chemists. Commercial cleaners should consult occupational health or Worksafe for guidance on PPE requirements.
It is important that draining and drying of flooded houses happens as quickly as possible after the flooding. To aid drying of your home you can:
If you are drying your property naturally, try and keep doors and windows open as much as possible. If using dehumidifiers, close external doors and windows.
Redecorating should also be delayed for at least three months after any repairs to prevent the risk of mould being covered.
If mould has developed on surfaces, take extra care when cleaning to reduce the risk of infection.
Most moulds are harmless to healthy individuals and occur naturally in our environment. However, some moulds (such as Stachybotrys chartarum - a greenish-black mould) can release spores/toxins that are potentially harmful.
Exposure to mould can lead to symptoms such as stuffy nose, wheezing, and red or itchy eyes, or skin, and the development of asthma. Some people, such as those with allergies to moulds or with asthma, may have more intense reactions. Severe reactions may include fever and shortness of breath.
The risk of respiratory illnesses caused by dampness and mould is particularly serious for young children and tamariki with existing conditions such as asthma.
Cleaning a property damaged by flooding effectively will reduce the risk of young children, tamariki and rangitahi (teenagers and young adults) developing colds, influenza, pneumonia and bronchiolitis in the future.
After a flooding there may be significant debris and waste outside your property which needs to be cleaned up and removed. It should be assumed that anything which has come into contact with floodwater is contaminated and may be a health hazard.
Put on protective clothing and ensure you have suitable gear prior to starting (see advice in Before cleaning up).
Contact Auckland Council if waste has been left for a long time and is beginning to become a serious hazard. Do not take items from skips, and minimise how much you disturb the items in the skip when putting in waste, to avoid shaking up dust and dirt.
Storm debris and waste can pose a number of health risks if not cleaned. The most significant risks include:
After a flood it is understandable to feel sad, distressed, worried, confused, anxious or angry, even if you’ve not been impacted personally. Everyone reacts differently to difficult events, and some people may find them more challenging than others. Remember it’s ok to not feel ok.
