CIVIL DEFENCE EMERGENCY MANAGEMENT GROUP PLAN 2009 – 2014 Version 1.16 August 2015 August 2009 Report no. 2009/EXT/1029 ISBN 978-1-877468-67-4 Foreword The members of the Manawatu-Wanganui Civil Defence Emergency Management Group have a growing understanding of the hazards and risks faced by communities in the Region, the measures that are in place to reduce the risks to the community, and options for future improvement in risk management. During the life of this Civil Defence Emergency Management (CDEM) Group Plan, much of the focus of emergency managers will be on building response capability. During this time, an emphasis on consistency, accountability, best practice and support will ensure that, should the worst happen, we are in a position to resist events and recover as quickly as possible. Whilst this Plan addresses the statutory requirements of the Group, the day-to-day workings are detailed in the Triennial Business Plan of the Group and the Annual Plans of members. The Co-ordinating Executive Group oversees the co-ordinated implementation of this Plan and the Business Plan on behalf of the Group. This Plan seeks to: Strengthen relationships between agencies involved in CDEM; Encourage co-operative planning and action between the various emergency management agencies and the community; Demonstrate commitment to deliver more effective CDEM through an agreed work programme–detailed in the CDEM Group Triennial Business Plan; and Provide information on the hazards and risks in the CDEM Group, and document the principles of operation within which agencies involved in CDEM agree to cooperate. The experience of members of the Group and the level of co-operation between members and supporting agencies is excellent. It is this spirit of co-operation that will assist communities to prepare for, respond to and recovery from emergencies when it counts. Approval The Manawatu-Wanganui Civil Defence Emergency Management Group Plan is approved by the Manawatu-Wanganui Civil Defence Emergency Management Group Joint Standing Committee with effect from 5 December 2009 and replaces the Plan approved on 4 March 2005. The Plan will remain in effect until reviewed by the Group and either amended, revoked, replaced or left unchanged. The review will begin no later than 5 December 2014. The Manawatu-Wanganui Civil Defence Emergency Management Group also approves the Triennial Business Plan 2010 - 2013 as the work programme of the Group. The Business Plan will be reviewed in line with CDEM Group and local authority planning and funding processes. ____________________________ 4/12/09 Chairman Garrick Murfitt Date Manawatu-Wanganui Civil Defence Emergency Management Group Joint Standing Committee Manawatu-Wanganui Civil Defence Emergency Management Group Plan 2009 - 2014 Manawatu-Wanganui Civil Defence Emergency Management Group Plan 2009 - 2014 TABLE OF CONTENTS CIVIL DEFENCE EMERGENCY MANAGEMENT ............................................................................... 1 GROUP PLAN 2009 – 2014 ........................................................................................................... 1 1.
