The Government has issued the terms of reference for an independent review into New Zealand's Civil Defence procedures.
The review will look at the Civil Defence's response to the devastating tsunami in the Samoas and Tonga on 29 September, with a focus on how public information was managed.
Civil Defence Minister John Carter says that while the overall response was good, there were clearly some issues with the way information was communicated to the public.
He says it is important that there are proper processes and procedures in place to respond to future events.
The review will be conducted by former Foreign Affairs and Trade secretary Simon Murdoch. It will run alongside the ministry's own review of its operational response.
Review topics include the development of public information messages by the National Crisis Management Centre, the use of the media to relay the information and the clarity and timeliness of warnings, advisories and messages.
Mr Murdoch is expected to report back by the end of October.
