Declaring a State of Emergency gives local authorities extra-ordinary powers to respond under the Civil Defence Emergency Management Act 2002.
Failure to comply could result in imprisonment for up to three months and a $5000 fine. A company can be fined up to $50,000.
In Hawke's Bay the authority to declare a State of Emergency resides with any member of the Hawke's Bay Region Civil Defence and Emergency Management Group ( CDEM).
CDEM is a partnership between Hastings District Council, Central Hawke's Bay District Council, Wairoa District Council, Napier City Council and Hawke's Bay Regional Council.
Its members are the respective mayors and regional council chairman.
Police, and non-police given the authority, may direct the evacuation and exclude people and vehicles from any place.
