Fire and Emergency, WorkSafe, the police and the insurance industry have been working together to reconstruct large portions of a Northwood house where a blast occurred on 19 July to understand what happened.
Fire and Emergency Christchurch Metro Area Commander, David Stackhouse said the investigation will likely continue over the coming weeks and will include the testing of several items of interest found at the blast site.
Personal belongings, including photo albums, have been recovered from a number of the properties badly affected by the explosion and returned to their owners.
"For many families photographs are their most important belongings," Mr Stackhouse said.
"Those working on the investigation were delighted that they were able to reunite many of the people affected by the explosion with these irreplaceable items."
The scene of the incident remains under guard while the investigation continues.
