As aftershocks from this morning's earthquakes continue, the Ministry of Civil Defence And Emergency Management is urging all New Zealanders to stay safe, take care of each other, keep calm and follow the advice of their local civil defence groups.

The tsunami warning has now been downgraded but some risk remains, says the CDEM.

Some evacuation notices are in the progress of being lifted.

For an update on the situation in your local area check with your local civil defence group.

The earthquakes and tsunami have affected different areas of New Zealand differently, says the CDEM.

"Local authorities are working as hard and fast as they can to take care of communities and build a picture of how New Zealand has been affected.

People in the earthquake affected area are being warned to check with your employer and with transport providers before leaving for work.

"Where possible stay out of damaged buildings and always check with building managers or owners before entering.

"There are widespread reports of damage and some initial reports of casualties but it is too early to confirm details. Local and central government authorities will provide more information as soon as possible.

"The public should watch out for fallen powerlines, broken gas lines and other damage that could be dangerous. Infrastructure damage should be reported to service providers," says the CDEM.

"Anyone in need of emergency assistance where life or property is threatened is advised to call 111."
