Collecting kai moana

Do not collect or eat kaimoana such as shellfish, ungutted fish, puha and watercress from waterways after an earthquake or flood. There is an increased risk of contamination from stormwater and sewage. 

Do not gather any dead fish or shellfish that have washed up on beaches, no matter how fresh they may look. They can contain harmful bacteria. 

Follow any rāhui in place by local iwi.

Getting rid of rubbish

• Listen for Civil Defence o the local council's instructions on getting rid of rubbish.
• Sort perishable and non-perishable rubbish and flatten any bulky items. 
• bury rubbish away from any water course, such as a stream or river. Cover each layer with soil and add lime or disinfectant to reduce smells. Mark all sites. 
• Compost all organic refuse if possible. 
• Store rubbish that cannot be buried or burnt in covered in containers or tightly tied rubbish bags, ready for collection. 
• Report any rubbish contaminated by hazardous substances to Civil Defence.
• Tell your insurance company about any condemned item of property before getting rid of it. If you do not have insurance, make a list of any items being dumped. Have it checked and signed by a responsible person in case you are eligible for a relief grant. Take photos if necessary to record what you are getting rid of. 

Disposing of sewerage

• Use makeshift toilets until you are told by authorities that it is safe to use flush toilets. 
• Use disinfectant or garden lime to reduce smells. Mark all toilet sites. 
• Get your septic tank pumped out to remove all silt and sludge if it has been covered by flood water. Septic tanks may not work properly until the level of water underground has gone down.

Keeping yourself healthy

• Make sure everyone helping with cleanup wear rubber gloves and wash their hands thoroughly before eating, drinking or smoking.
• Disinfect any cuts and cover with a waterproof dressing. 
• Keep tamariki (children) away during the cleanup phase. 
• Take precautions against insect bites by using repellants and wearing trousers and long-sleeved tops. 
• Wash any clothing, bedding and contaminated materials, such as curtains, using detergent. Rinse in clean water with added household bleach to kill any bacteria. 
• Get rid of contaminated clothing so that people do not find it and put it on. 
• Go back to normal showering, bathing and clothes washing as soon as there is spare clean water.

Accommodation

If you had to leave your house during an emergency, before you return:

• contact an electrician or the electrical supply authority before switching water back on again if water has reached underfloor wiring, wall sockets, or the structure has been damaged by an earthquake
• contact gas supply authorities if the gas meter has been affected by water 
• make sure the local authority health and plumbing officers have checked that the water supply and sewerage systems are safe and working properly. 

Soon after heavy rains have stopped and waters have drained off the ground surface, sewers will generally return to normal function. It is important to clean up drains and dry out the house as quickly as possible. 

'Floods and health' has advice on restoring a house and cleaning out your basement after flooding.
