A review into how fire authorities handled Christchurch's Port Hills fire will seek to improve how they respond to future disasters.
The terms of reference and investigation team have been announced for the operational review of the official response to the Port Hills fires.
Two fires started on February 13 and later merged into one as they damaged 11 houses and burned through 1645 hectares. The fire was officially declared extinguished on April 21 – 66 days after it began.
It was fought by rural fire fighters, full time Fire Service staff and volunteers.

Internal Affairs Minister Peter Dunne said the terms of reference established "core guidelines and principles" about how the independent review would be carried out.
It aimed to assess the "readiness" of fire agencies when the fire erupted, as well as post-incident management, and would provide recommendations to "enhance the effectiveness and efficiency" in how fire agencies worked.
The operational review is sponsored by the New Zealand Fire Service and the National Rural Fire Authority.
Alan Goodwin, of the Australasian Fire and Emergency Authorities Council, has been named as lead reviewer. He has over 25 years of experience in the industry.
Dunne said having an independent reviewer would "help ensure the findings are objectively assessed".
New Zealand Fire Service national operation efficiency manager Trevor Brown and Auckland Council principal rural fire officer Bryan Cartelle will round out the review team.
An initial report on the findings is expected in about two months. It is hoped the findings will be released around October, following a consultation process.
The Christchurch City Council and Selwyn District Council are developing linked but separate fire recovery plans. They are intended to go to their respective councils in late May or early June.
The investigation into the cause of the fire is ongoing. The cost of the firefighting efforts is still unclear, but is expected to be known early this month.
New Zealand's rural and urban fire authorities are due to merge on July 1, and will be renamed Fire and Emergency New Zealand.
