NZ Police Role<br />
The Guide provides details <strong>of</strong> <strong>the</strong> role <strong>of</strong> <strong>the</strong> Police, which includes to:<br />
• assist with <strong>the</strong> dissemination <strong>of</strong> warning messages; and<br />
• assist <strong>the</strong> movement <strong>of</strong> rescue, medical, fire and o<strong>the</strong>r essential services; and<br />
• coordinate movement control over land, including communications and traffic control; and<br />
• conduct any initial evacuations to ensure protection <strong>of</strong> life.<br />
The Act gives <strong>the</strong> Police certain powers during a state <strong>of</strong> emergency. These include to:<br />
• evacuate any premises or place, or exclude persons or vehicles from any premises or place<br />
where such action is necessary for <strong>the</strong> preservation <strong>of</strong> human life; and<br />
• totally or partially restrict public access to any road or public place.<br />
The Role <strong>of</strong> Science and Research Organisations<br />
Science and Research Organisations (universities, Crown research institutes, private organisations and<br />
international networks) also play a part. As detailed in <strong>the</strong> Guide, <strong>the</strong>ir role is to assist with:<br />
• hazard monitoring; and<br />
• <strong>the</strong> provision <strong>of</strong> hazard and risk information; and<br />
• scientific advice to agencies managing an emergency; and<br />
• public information on hazards and risks and safety measures.<br />
National Warning System<br />
The Guide covers national warnings and advisories which are intended to provide information about<br />
<strong>the</strong> potential or actual threat. The Guide identifies that “effectiveness <strong>of</strong> a warning or an advisory<br />
depends on:<br />
• <strong>the</strong> timeliness <strong>of</strong> <strong>the</strong> warning or advisory; and<br />
• <strong>the</strong> delivery and receipt <strong>of</strong> <strong>the</strong> national warning or advisory; and<br />
• <strong>the</strong> recipients understanding <strong>of</strong> <strong>the</strong> necessary action to be taken in respect <strong>of</strong> <strong>the</strong> particular<br />
threat; and<br />
• <strong>the</strong> readiness and response from <strong>the</strong> national, CDEM Group or local levels”.<br />
National warnings and advisories are provided by MCDEM to CDEM Groups, local authorities,<br />
emergency services, agencies, lifeline utilities and broadcasters. CDEM Groups are responsible for<br />
disseminating national warnings to local communities and maintaining local warning systems.<br />
Warnings and advisories may be issued for any type <strong>of</strong> hazard. The type <strong>of</strong> warning or advisory will<br />
depend on <strong>the</strong> hazard type and potential impact. The Guide states that use <strong>of</strong> <strong>the</strong> national warning<br />
system should follow this procedure:<br />
• An alert notification system feeds information about <strong>the</strong> environment to MCDEM.<br />
• MCDEM analyses <strong>the</strong> information and decides what to do.<br />
